Stas Sergeev (stsp), C. Masloch, Jiri Malak, Bernd Böckmann
* support determining kernel file version without booting it
* only print messages once, not each time processing partitions
* fix for Format GitHub issue #1 - format divide by 0 due to kernel function 440D, subfunction 60 returning a zero for logical_sectors_per_fat as initdisk overflows and calculates incorrect value
* From bzt, initialize drive parameter head & sector values to avoid potential divisions by 0
* config: allow to delete variable with empty SET command
* truename: fix array overrun (pick from fdpp)
* main: insure master environment starts out empty
* config: make sure word marker trailing in environment is zero
* inthndlr: align hma size to para
* DosGetExtFree: Use new redirector function 11a3
* sys: detect small FAT32 as FAT32 (zero in word SPF)
* boot: enable loading from file systems with 256 sectors per cluster
* fatfs.c: allow bpbSectorsPerCluster == 0 to mean 256
* FCB (int 21h func 29h): should not accept field separator as "drive letter"
* FCB (int 21h func 29h): should keep parsing name even if drive letter invalid
* exeflat: update usage screen with -E, -D, and -U switches
* upxentry, upxdevic: add header comments
* exeflat: improve compressed stub handling, fixes, update documentation, various other updates
* kernel: optimise A20 check and enable/disable calls
* improve/fix gcc and OpenWatcom build support
* task: return Invalid format on empty executable (fixes #70)
* fdkrncfg: bugfix, version info check should not include signature
* fix 2nd parameter of "DOS=" statement in config.sys does not take effect in some cases:
* dosfns, int2f: make SHARE uninstallable
* CI: improvements
* Fix incorrect date format for Czech and Slovak Republic. Both Countries use DD.MM.YYYY date format. Microsoft DOS also use this format.
* dosfns: Check share table before delete/rename
* various build updates and move share and country to submodules
* FCB: Rename should support asterisk wildcards - based on dosemu fdpp, fixes issue #43
* add tests for FCB rename - based on tests from andrewbird
* allow opening a character device prefixed with invalid drive letter (e.g. "@:NUL") but not with invalid path
* add test for opening character devices (all pass on DOS 5,6, NT VDM, @:dev fail currently on FD kernel)
* initial implementation of extended seek (0x7142 - LONG LSEEK with 64-bit file position)
* add implementation of int 0x2F function 0x1f build CDS from dosemu2/fdpp
* add skeleton for LFN API, includes 0x71a6 implementation (call to redirector only) from dosemu2/fdpp
* ensure offset to critical patch tables doesn't change
* From Tom Ehlert: don't split disk transfers crossing DMA boundary if BIOS indicates can handle transparently
* fcbfns: Fix for FcbFindFirstNext [fixes #40]
* task: don't zero parent_psp on 0x26
* boot, oemboot: fix to abort properly on file not found
* oemboot: optimise FAT12 entry loading (picked from lDOS boot)
* adjust padding to be same as in PC-DOS (90h/nop)
* from RBIL int 21h/4400h (table 01423) add definition for bit 11 if SFT is not for a device (for a file) - media not removable, currently unused
* from dosemu2/fdpp - zero out critical patch list Personal NetWare Server really writes to these addresses, so putting 0x0d0c the way DOS does, is not safe.
* int 21h/4400h only return low byte of SFT flags if not a device, part of dosemu2/fdpp bug #147 fix
* check for unsupported function call in console - from dosemu2/fdpp bug# 101 fix
* improve support for Windows 3 Enhanced mode

2012-10-15 02:08:06 +02:00
2012 Feb 07 - Build 2041
-------- Jeremy Davis
+ Changes Jeremy
* r1637 fix out of range byte in country.asm
* r1685 add int 2f subfunc 122B and 122D from Eduardo Casino
* r1697 from Pete Batard, do not display CHS mismatch warning
during booting when forcing LBA mode option set
* r1702 improve handling for sectors not 512 bytes in size
(up to 2048 bytes, larger sizes not yet working)
* r1705 add cpu detection so memdisk args supported in 8086 build
2011 Jun 21 - Build 2040
-------- Jeremy Davis, Bart Oldeman
+ Changes Jeremy
* r1635 from Christian Masloch, correction for memdisk check
* r1634 optional CONFIG.SYS options via memdisk
* r1633 force DPT to 512 byte sectors
* r1501 sys/sys.c: correct return value from NULL to FALSE -
fix compile with OW1.9
* r1500 docs/sys.txt, sys/sys.c:
handle case when source not specified but filename for boot
sector is given (sys X: bootfile.bin)
+ Changes Bart
* r1632 make free cluster search circular
* r1631 do not use FSINFO if not valid
* r1609 truncating 0 byte file should not fail
* r1591 fix SF bug 3090610 - 386 register save/restore
* r1569 kernel/{config.c,kernel.asm,init-mod.h,globals.h}:
Allocate bigger chunk of memory for INSTALL for __WATCOMC__
because the memory layout is different from other compilers.
Fixes issues mentioned by Bret Johnson and Christian Masloch
in freedos-user/freedos-kernel.
* r1568 kernel/asmsupt.asm, mkfiles/owlinux.mak: Make sure the
DOS native and Linux cross-builds produce identical binaries.
* r1567 drivers/rdpcclk.asm,kernel/{asmsupt,entry,irqstack,kernel,
nls_hc}.asm, kernel/makefile:
Remove useless END from nls_hc.asm, add explicit byte
overrides for older versions of NASM for more compact code,
and adjust silent relocation segments.
* r1565 sys/sys.c: Change // to /* comments for Turbo C compatibility.
* r1564 kernel/dosfns.c: If handle valid, close file in PSP
table before the low-level close + (perhaps) critical error.
Avoids closing the file twice (and hitting the critical
error twice) on abort/program termination.
Also, close can only return error 6 (DE_INVLDHNDL), not 5
(DE_ACCESS), see RBIL.
* r1563 kernel/task.c: From Christian Masloch:
set flags to 0x200 (IF set) when transferring to int22
termination address.
* r1562 kernel/fatfs.c: Check errors for callers of dir_write
and shrink_file. Fixes: Bug: File creation does not check
whether buffers are written correctly
(http://www.bttr-software.de/forum/forum_entry.php?id=9783)
* r1561 kernel/blockio.c, kernel/fatdir.c:
No longer force flush1() and dir_write_update() to return
TRUE if there were disk write errors. Part 1 for fixing
http://www.bttr-software.de/forum/forum_entry.php?id=9783
Bug: File creation does not check whether buffers are
written correctly
* r1560 kernel/kernel.asm:
Enlarge clock and block driver stacks. Thanks to Damien Guibouret
<damien.guibouret@partition-saving.com>.
* r1559 kernel/fatfs.c: Fix value that is used before being initialised.
This lead to a drive to not be considered as FAT32 despite it is
(or vice-versa).
Thanks to Damien Guibouret <damien.guibouret@partition-saving.com>.
* r1499 kernel/makefile:
With the stack changes the DOS segment has moved to 0x79.
* r1498 kernel/irqstack.asm:
New irqstack.asm: irq 2, 3, 4, 5, 6, 10, 11, 12, 14, 15 now
use the IBM interrupt sharing protocol for STACKS. Affect
int 2 too, but not IRQ 7 (INT 0fh) and IRQ 9 (INT 71h)
2009 Aug 04 - Build 2039
-------- Jeremy Davis, Bart Oldeman
+ Changes Jeremy
* r1494, 1483 docs/sys.txt, sys/sys.c: update documentation to
include new options; add option to sys to force LBA or CHS
usage, allow using BIOS specified boot drive # on floppy,
add verbose output (debug prints), and reorder some steps in
copy() to avoid some unnecessary disk swaps on single drive systems
* r1493 boot/boot.asm: add comment about location that may be
modified by sys (and some whitespace changes due to editor)
* r1492 boot/makefile: create list file when assembling boot sectors
* r1489 kernel/main.c: update copyright year, add some comments
* r1488 kernel/kernel.asm: mark unused space in kernel for unused win
compatibility structs
* r1487 hdr/lol.h, hdr/win.h: comment/structure info update
* r1486 hdr/process.h: comments added
* r1485 hdr/device.h: comments added
* r1484 hdr/cds.h: update comments
* r1483 docs/sys.txt: update sys usage documentation
* r1482 boot/boot.asm, boot/makefile, boot/oemboot.asm,
build.bat, default.bat, hdr/debug.h, kernel/{dosfns.c,init-mod.h,
initdisk.c,inthndlr.c,prf.c,proto.h},sys/{fdkrncfg.c,makefile,sys.c}:
update sys to current version, adjust printf to support
percent modifier, consistent prototype, and handle text not in
current segment (FAR *) better, merge part of simplified debug (via
prints) support
* r1467 kernel/makefile, mkfiles/generic.mak: update build process to
include country.sys
* r1466 kernel/country.asm: sync country source with latest from
eduardocasino.es site
* r1465 kernel/country.asm: add source for country.sys from dev
branch
* r1456 hdr/version.h, kernel/globals.h: simplify how version
specified, enable SVN builds with revision#
* r1455 build.bat: add convenience options to build.bat for setting
various defines
* r1454 default.bat: clear some additional env variables
* r1431 kernel/makefile, utils/exeflat.c: More verbose output of UPX
method (sys or exe) used and fix case without UPX so kernel boots.
* r1385 docs/fdkernel.lsm, hdr/version.h: update version # in
preparation for next release and to avoid confusion between svn and
release kernels
+ Changes Bart
* r1491 hdr/debug.h, kernel/{init-mod.h,kernel/int2f.asm,nls.c,prf.c,
proto.h}, sys/{fdkrncfg.c,sys.c}: Use near pointers for printf()s
where possible. Problematic is only the case where SS!=DS (which
happens sometimes in resident code), in which case va_list/va_arg
need to use FAR pointers. DS!=DGROUP never works, so I corrected
that for NLS_DEBUG, by setting DS in int2f.asm.
* r1490 kernel/fatfs.c: Check the BPB instead of the DPB for FAT32
after a BUILDBPB device call, as the DPB may still be uninitialized
at this point. Fixes FAT32 drives in USBDRIVE (http://bretjohnson.us)
* r1480 utils/exeflat.c: Corrected a bug in exeflat: it was writing
32 bytes too many from possibly unexisting buffers after compressing
exe files.
* r1479 kernel/{initdisk.c,newstuff.c}: Corrected DEBUG #if to
#ifdef for Turbo C and corrected debug printfs in truename().
* r1478 kernel/newstuff.c: Simplified truename(): eliminated the
addSep state by adding a backslash in every new segment, including a
trailing backslash. Simplified . and .. logic. Converted switch to if
because there were few cases left.
* r1477 kernel/dosfns.c: DosChangeDir can only return DE_PATHNOTFND
in case of error, so force that error code.
* r1476 kernel/dosfns.c: Remove the wildcard check for DosChangeDir()
because truename() already does that.
* r1475 kernel/newstuff.c: Use simpler code for copying the current
directory constructing the "truename": instead of fmemcpy followed by
strcpy, just use strcpy. Also use the near TempCDS more.
* r1474 kernel/newstuff.c: Unify parse_name_ext for name and
extension and inline this function into truename(). This is an
optimization (200 bytes).
* r1473 kernel{fatdir.c,fatfs.c,newstuff.c}: If the current directory
is no longer valid, call dos_cd() for the root to update the CDS
cluster. Call media_check explicitly in truename() as a central
first and only place in directory-using DOS calls (except
DosFindNext) to call it.
* r1472 kernel/{dosfns.c,newstuff.c}: The original DosGetCuDir
is now inlined in truename(). DosGetCuDir now does truename("D:",
CDS_MODE_SKIP_PHYSICAL), and this mode was changed to no longer call
QRemote_Fn (int2f/ax=1123).
* r1471 kernel/newstuff.c: Fix truename("C:") where the current
directory is different from the root: then it should not append a
backslash.
* r1470 kernel/{inthndlr.c,makefile}: Turbo C 2.01 and Linux
cross-compilation compatibility fixes.
* r1469 kernel/{inthndlr.c,task.c}: For self-owning PSPs do
everything that a normal exit does except for closing files and
releasing memory (see RBIL). Thanks to Christian Masloch.
* r1468 kernel/fatdir.c: Fix problem with cd\ reported by
ibid_ag@lavabit.com on the mailing list.
* r1458 kernel/{blockio.c, fatfs.c, proto.h}: In case of
"not sure" if the removable media has changed, the IBM PCDOS
technical reference says to call BLDBPB if there are no used buffers,
so we only do it then, instead of flushing the buffers.
* r1457 hdr/{xstructs.h, inthndlr.c}: Merged int21/ax=7304,
subfunctions 3 and 4, which work very similarly.
* r1453 kernel/fatfs.c: Set the clean bit also on created/replaced
files, not just opened files, so the directory entry is only updated
after they are written too. Fixes SF bug #2380531.
* r1452 kernel/initdisk.c: Use a better formula for calculating FAT12
clusters, by multiplying nominator and denominator by 3.
* r1451 kernel/{fatfs.c, initdisk.c}: initdisk: further optimizations
in CalculateFATData(): merging the FAT16 & FAT32 loops.
fatfs: #if DEBUG fix.
* r1450 kernel/initdisk.c: Optimized initdisk.c by using constants
instead of variables where possible.
* r1449 kernel/config.c, kernel/config.h: Removed unused config
variables and don't detect 'y' and 'n' if we're using toupper anyway.
* r1448 hdr/{fat.h, fatfs.c}: Cluster optimizations, mainly for FAT32
eliminated checkdstart, replaced (cl == FREE || cl == 1) by (cl <= 1),
UWORD cluster cast for FAT12/16, and merge if branches for link_fat().
* r1447 kernel/fatfs.c: Merged if status==S_OPENED logic in dos_open,
cache dir_attrib, and remove unnecessary init to 0.
* r1446 kernel/config.c: Make the built-in COUNTRY table more compact
and allow to merge duplicate strings for error message.
* r1445 kernel/fatfs.c: Optimization: changed find_fname() to call
split_path() because find_fname was always preceeded by split_path().
The return code is now an error code, DE_FILENOTFND, DE_PATHNOTFND,
or SUCCESS, depending on the failure.
* r1444 kernel/{fatdir.c, fatfs.c, proto.h}: Added a
split boolean argument to dir_open so the trick with setting the
dir/filename separator to 0 can be avoided, and we don't need to
calculate its location in split_path(). Without the trick many more
char * path arguments in the kernel can become "const char *".
* r1443 utils/exeflat.c: Use tmp.exe instead of tmp$$$$$.exe -- the
Linux cross compilation really has trouble without quotes because $$
can be expanded as a shell variable when passed to system().
* r1442 kernel/{dosnames.c, fatfs.c, makefile, proto.h}:
Remove dosnames.c and inline ParseDosName, because there is only one
user left (split_path()) which only uses it to find out if the path
ends in a backslash and the length of the directory part.
* r1441 kernel/{dosnames.c, fatdir.c, fatfs.c, proto.h}:
dos_findfirst() now uses split_path(). The only thing
that needed to be added was the need to check for "d:\" paths which
return DE_NFILES. Also, findfirst("d:\nonexist\*.*",D_VOLID) should
fail even if it actually searches in d:\.
* r1440 kernel/{dosnames.c, newstuff.c}: The invalid pathname
character detection is moved from ParseDosName (dosnames.c) to
truename (newstuff.c), because TRUENAME should check these characters
before passing paths on to fatfs.c & fatdir.c.
* r1439 kernel/fatdir.c: Corrected the if-statement && logic for
attributes in the findnext loop.
* r1438 kernel/{dosfns.c, fatdir.c}: Make findfirst/findnext
more MSDOS compatible:
* ignore 0x40 (D_DEVICE) in search attribute.
* if you specify D_VOLID + one or more of D_HIDDEN, D_SYSTEM, and
D_DIR you will get files *and* volume labels in the specified
directory, not forced to the root directory.
* VOLID searches must look at the search pattern name too,
or do not match.
* r1437 kernel/{dosfns.c, fatfs.c}: For read/write don't update
sft_posit in dosfns.c anymore so fatfs.c takes care of it.
* r1436 kernel/{fatdir.c, fatfs.c}: Remove usage of the fnode
f_flags field where it is not relevant anymore. Because of the
explicit dir_write() calls we only need them in situations where SFTs
where used, that is for open files but not for directories.
* r1435 kernel/{fatdir.c, fatfs.c}: Eliminate fcbname[] on the
stack: we can use dm_name_pat in the dirmatch structures instead.
* r1434 kernel/asmsupt.asm: %if 0 unused asm functions and fix a
stack return problem with fstrcmp.
* r1433 kernel/{dosnames.c, fatdir.c, fatfs.c, proto.h}:
Split 8.3 FCB-style filename extraction from ParseDosName
into a new ConvertNameSZToName83 function, also used by dir_open().
* r1432 hdr/fnode.h, kernel/{fatdir.c, fatfs.c, globals.h, init-mod.h,
kernel.asm}:
Move the fnode fields f_diroff and f_dirstart into a referenced
directory match structure with fields dm_entry and dm_dircluster.
* r1430 hdr/nls.h, kernel/{config.c, init-mod.h, inthndlr.c, intr.asm,
kernel/nls.c, kernel/nls_hc.asm, kernel/proto.h}:
Ported COUNTRY.SYS support from the unstable branch.
Simple country support is kept: COUNTRY=31 will look for country.sys
but if it does not exist, not complain and load the built-in info.
* r1429 hdr/sft.h, kernel/{dosfns.c, inthndlr.c, proto.h}: Seek changes:
* merge unstable kernel optimizations
* enable seek for int2f/AX=1228
* -1 is a valid offset, so we need to process the return code
seperately
* r1428 kernel/dosfns.c: Merge pop_dmp optimization from the unstable
kernel.
* r1427 kernel/ioctl.c: This change was missed, as the changelog
mentioned it was in 2035a already: r_si/r_di contents added as
documented in PC-DOS Technical Update. I also moved the CharReqHdr
filling in to just before execrh, and made the command table a static
const so it is outside the SDA (OW places it in CONST2).
* r1426 kernel/ioctl.c: Optimization: move the attribute checks down
and localize some variables.
* r1425 kernel/ioctl.c: Streamline ioctl.c code so OW saves 2 more
words of stack.
* r1424 kernel/ioctl.c: r1115 set the dpb_subunit but that was wrong
for get_cds() called from AX=4409. Use a local variable unit to avoid
that, and simplify the AX=4409 logic like in the unstable kernel.
* r1423 kernel/ioctl.c: Inline ioctl helper routine back again. Save
stack by using the dev variable that points to the device smartly.
* r1422 kernel/ioctl.c: Split DosDevIoctl into two calls so execrh
can be called with minimal stack usage. Always return DE_ACCESS when
the device fails instead of DE_DEVICE, as DE_DEVICE is only used for
renames between devices that are not the same.
* r1421 kernel/fatfs.c: Introduce clear_dir() to clear a directory,
this was code shared between dos_mkdir() and extend_dir(). Now
dos_mkdir() calls this function to clear the new directory, and then
creates the . and .. entries using higher level functions instead of
dealing with the blocks directly.
* r1420 hdr/{fnode.h, sft.h}, kernel/{fatdir.c, fatfs.c}: Make
the fnode f_flags completely equal to the SFT sft_flags. Rename
SFT_FDIRTY to SFT_FCLEAN to avoid confusion.
* r1419 hdr/fnode.h, kernel/{fatdir.c, fatfs.c}: Eliminate the
fnode F_DDIR flag which has no SFT equivalent: f_sft_idx==0xff can do
the same. rwblock() is never called for directories so the checks
could be removed.
* r1418 kernel/fatfs.c: Flip target and source checks to avoid
calling ParseDosName for in-directory renames. Do not allow to rename
directories between different directories.
* r1417 kernel/fatfs.c: RENAME: if the source and target directories
are the same, rename the directory entry in-place instead of creating
a new one and deleting the old one. Fixes archived bugzilla bug:
http://www.freedos.org/bugzilla/cgi-bin/show_bug.cgi?id=1908
* r1416 kernel/fatfs.c: Change dos_rmdir to only use 1 fnode. It now
first checks if the directory is empty and then opens the parent and
deletes the real directory. No longer returns DE_FILENOTFND(2), but
return DE_PATHNOTFND(3) instead.
* r1415 hdr/dirmatch.h: Cleanup dirmatch.h: make attributes and size
unsigned, and make the unused dm_flags field reserved.
* r1414 kernel/{dosfns.c, proto.h, task.c}: Introduce get_cds1 to merge
common code that checks for 0=default_drive,1=A,etc.
Make load_transfer() static.
* r1413 kernel/chario.c: Inline cooked_write_char() into cooked_write().
* r1411 kernel/fatfs.c: Fix compilation with Turbo C.
* r1410 kernel/{fatdir.c, fatfs.c, proto.h}: Eliminate dir_close().
Its only purpose left was to flush buffers, which isn't necessary
after just open/read, so we can move that to dir_write().
* r1409 kernel/{dosfns.c, fatfs.c}:
Move the open/creat access checks to more efficient places.
* r1408 kernel/fatfs.c: Make merge_file_changes more direct dealing
with SFTs and merge the "close open files setfattr wants to change"
functionality there.
* r1407 kernel/dosfns.c: Eliminate DosGetFile -- it is no longer
necessary because the filename is already copied from the fnode.
* r1406 kernel/dosfns.c: Fix a regression with sft_flags overwriting
what dos_open wrote so file dates/times would always be updated, even
for reads!
* r1405 kernel/{dosfns.c, fatdir.c, fatfs.c, fcbfns.c, proto.h}:
Eliminate dos_setfsize, dos_setftime, and dos_lseek, by just using
the SFT. dos_setfsize still needed to merge changes for SHARE so the
call was replaced by a new dos_merge_file_changes() call.
* r1404 hdr/fnode.h, kernel/{fatdir.c, fatfs.c}: Eliminate
xlt_fd(), save_far_f_node(), and the redundant fnode f_mode field.
* r1403 kernel/{dosfns.c, fatfs.c}: Let merge_file_changes
operate directly on the other SFTs. dos_setfattr with SHARE now
closes open SFTs referring to that file in compat mode.
* r1402 kernel/fatfs.c: Fix SFT/fnode fields so the SHARE related
functions is_same_file() and merge_file_changes() work.
* r1401 hdr/fnode.h, kernel/{fatfs.c, globals.h}: Remove
redundant checks for fnodes==0 since the checks are done in dosfns.c.
Replace global f_nodes[] array by f_sft_idx fields in the fnodes.
* r1400 hdr/sft.h, kernel/{dosfns.c, fatfs.c, fcbfns.c, proto.h}:
Eliminate the sft_status field as it is now equal to the SFT index.
* r1399 kernel/{dosfns.c, fatfs.c, proto.h, task.c}:
Eliminate dos_getftime, dos_getfsize, and dos_getfattr_fd, because we
can now get these properties directly from the SFT.
* r1398 hdr/fnode.h, kernel/{fatdir.c, fatfs.c, proto.h}:
Eliminate f_count field in fnodes and some no-op functions.
* r1397 hdr/{fnode.h, lol.h}, kernel/{config.c, dosfns.c, fatfs.c,
globals.h, kernel.asm, proto.h}:
This is the main change to eliminate far fnodes. SFT info is copied
from and to the two near fnodes. Some cleanups still follow.
* r1396 hdr/sft.h:
Make the SFT DOS 4+ compatible and change fields to be unsigned.
* r1395 kernel/dosfns.c:
Handle sft_count before calling dos_open and after calling dos_close
so the SFT is open for longer, during fatfs.c operations.
* r1394 kernel/prf.c: Fix compilation with -DDOSEMU set.
* r1393 kernel/{dosfns.c, fatfs.c}: Handle dos_getfattr and
dos_setfattr directly at the directory level, instead of opening the
file, to avoid needing to claim SFTs in later changes. Clarify and
implement parts of the correct SHARE behaviour.
* r1392 hdr/fat.h, kernel/{fatdir.c, fatfs.c, proto.h}:
On close or commit, only update those directory entry fields that
have an SFT equivalent. The rest stays unmodified on disk.
* r1391 kernel/{fatdir.c, fatfs.c}: Use explicit dir_write()
instead of letting dir_close() do the writing. This is to prepare for
an updating version to deal with SFTs.
* r1390 hdr/fnode.h, kernel/fatdir.c: Add f_dirsector (sector
containing dentry) and f_diridx (index within sector) fields to the
fnode, to make fnodes more compatible with SFTs. Use them to simplify
dir_read() and dir_write().
* r1389 kernel/{fatdir.c, fatfs.c, globals.h, inthndlr.c, lfnapi.c,
proto.h}: Force near fnode use to use either fnode[0] or fnode[1]
instead of the allocation scheme. This eliminates the checks
done in inthndlr.c because the f_count field is no longer checked.
* r1388 makefile, mkfiles/owlinux.mak: Change Linux makefiles to only
update what is necessary for subsequent makes.
* r1387 config.m, docs/build.txt, drivers/makefile, kernel/{makefile,
segs.inc}, makefile, mkfiles/{generic.mak, owlinux.mak, watcom.mak},
sys/makefile, utils/{exeflat.c, makefile}:
Add Linux cross-compile capability, using Open Watcom:
* Flip \ to / where possible.
* Introduce $(DIRSEP) (/ or \) for use inside commands in
makefiles where / won't work in DOS.
* Override various settings for Linux in owlinux.mak.
* Add quotes in exeflat.c to avoid shell expansion of $$$$$.
* Let "make all", "make clean", and "make clobber" do the job.
* r1386 utils/echoto.bat: OW 1.8 MS2WLINK is too picky about leading
and trailing whitespace so echoto is changed to not generate any.
2009 May 16 - Build 2038
-------- Pat Villani, Bart Oldeman, Eric Auer
Thanks to Geraldo Netto for summarizing the 2008 SVN changelog. See also:
http://freedos.svn.sourceforge.net/viewvc/freedos/kernel/trunk/?view=log
Patches are mostly from Bart and Eric, some from Jeremy and Tom.
+ Changes Jeremy 2009
* r1412 from Eric: update this history.txt (and bugs.txt, contrib.txt)
* r1381-r1384 update bugs.txt version.h LSM, tag SVN for 2038 release
* r1374, r1380 fcbfns FCB open old GEM compat (bigsize/recsiz/recno)
http://sf.net/tracker/?func=detail&aid=2253450&group_id=5109&atid=355109
* r1379 dosfns.c fatfs.c proto.h from Eric: only check for SHARE on
open/close, avoid extra 2f.1000 calls.
* r1378 dsk.c from Lucho: Press any key, not Press the any key ;-)
* r1377 initdisk.c from RayeR: Use total cyl count, not max cylinder
(fixes off by one bug on non-LBA PC) & fix overflow by ULONG cast.
Improve DebugPrintf calls, fix format string (only in debug kernels)
* r1376 inthndlr.c from Tom: 21.1c return AL=0xff for invalid drives
(fixes bug for apps which use int 21.1c to find FAT drive letters)
* r1372, r1375 from Bart: process.h/entry.asm make CP/M call PSP[5]
work (1 line jbe versus ja fix and detailed comments about stack)
This fixes SF tracked bug 2421577.
* r1373 kernel.asm add : after _HMATextAvailable avoid nasm warning
* r1371 watcom.mak make sure even Windows Watcom C builds a DOS SYS
(would otherwise make a SYS meant for use in Windows by default)
* r1370 default bat make compiling without UPX possible again
* r1369 let DosGetExtFree 21.7303 accept drive with and w/o slash
This fixes SF tracked bug 2380828 (GetDiskFreeSpaceEx if no slash)
* r1368 tag for ke2038test
+ Changes Bart + Eric (mostly)
* r1367 sys.c from Bart: 32bit date/time if WATCOMC 1279+ (OW 1.8)
* r1366 config.c, config.txt allow BUFFERSHIGH as alias to BUFFERS,
buffers are in UMB, we use HMA anyway. Drop unused int 16.1 call.
* r1365 inthndlr.c allow/ignore type hints in int 21.7305 disk read
* r1364 fdkernel.lsm and version.h updated to 2038 / Apr 2008
Updated this history.txt changelog to state of April 2008
* r1363 add Geraldo (changelog) and Fritz (docs) to contrib.txt
New version of config.txt - verbose, readable, up to date
* r1362 update readme.cvs - add info about SVN / subversion
* r1361, 1355 update information about bugzilla. You can also
write the maintainer or mailinglist but we prefer bugzilla...
Add information about SourceForge feature request tracker, too
* r1360 new Free Software Foundation (FSF) mail addr in COPYING
* r1359 BIOS y2k bug workaround: If BIOS date 1900..1979, assume
date 2000..2079 (we only read CMOS date at boot) Fix bug 1748
* r1358 more secure FAT handling to avoid crosslinks if reboot
with open files: Thanks to Hardi Stengelin for research help;
always test link_fat result, new is_free_cluster, checks in
link_fat and next_cluster (bad index/value, bad chain / extend
-> warning). Do link_fat before setdstart. Lazy FS INFO writes
* r1357 truename must use the current working directory of the
created-by-subst virtual drive when it resolves relative paths
even though the "real" drive/dir are returned in the end. Note
that "subst e: d:\" shows a warning as it tries "mkdir d:\"
Fixes bug 1862 "CHDIR fails on substituted drives"
* r1356 SYS has to update the backup boot sector of FAT32, else
dosfsck would show a warning about a boot / backup mismatch
* r1354 Use _dos_allocmem for OW, similar to Turbo C version
Split file copy into readfile and writefile, nicer source code
Preserve time and date of kernel.sys and command.com
* r1353 let exeflat call UPX, simpler makefile as in unstable branch
* r1351, 1352 exeflat reorganization, no functional changes
* r1350 add ASM/CDECL to HaltCpuWhileIdle decl, fix Turbo C compile
* r1349 change copy() in SYS to "read to RAM, update boot, write to
disk", reduces disk changes on single floppy PC, fixes bug 1840
* r1348 treat load image size of EXE modulo 1 MB, do not abort if
size > 1 MB. Fixes bug 1854, Turbo C++ 3: paras=(word)(pages<<5)
* r1346 init HaltCpuWhileIdle to 0 before installing int handlers
* r1345 int 21.5a mktemp: only enforce root tempfile name if no dir
is given in template *and* DOS version is 5.xx, else no dirspec
Tried to make int 21.60 truename return 0 if okay, 3a00 if char
device and not join/net?? Set default FAT16 DOS version to 6.22
(was 5.0, only int 21.5a/21.60 and userland differ from 6.22)
* r1344 clarified intfns.txt for int 21.63 (country/nlsfunc), int
21.71 (LFN) and int 21.5d0x (share). The latter would need both
kernel and SHARE extension to be supported, neither are done yet
* r1341, 1343: fix Bochs incompatible (PostConfig crash) IRQTEXT,
now with corrected segment loads in irqstack.asm (segs->groups)
This fixes a problem introduced in SVN revision 1325/1326. We now
have a "fastboot" int 19 reboot hook from Japheth's JEMM JEMFBHLP
* r1342 fix fat32readwrite prototype, reg use in detect LBA pragma
2007 Jul 21 - Build 2036 svn, in other words, 2038 pre
-------- Eric Auer (eric@coli.uni-sb.de)
Thanks to Geraldo Netto for summarizing the SVN changelog - See also:
http://freedos.svn.sourceforge.net/viewvc/freedos/kernel/trunk/?view=log
All main features of Tom's fork are available in kernel 2038 now.
+ Changes Bart + Eric
* r1340 version 2038pre/2036svn (fdkernel.lsm, version.h, history)

(relocate keyboard buffer, eg to 40:105-1ff) config.sys options
* r1338 removed "Dutch plurals" ("Dutch plural's" ;-))
* r1336-1337 disable interrupts while storing interrupt vectors,
fix 8086 compatibility again
* r1335 use lastdrive Z for initial CDS, so device=f:... etc works
* r1334 fix bug 1953: int 21.29 now returns valid only for existing
drives, not for all, and leave FCB empty/unset if no valid drive
http://sf.net/tracker/?func=detail&aid=2362450&group_id=5109&atid=105109

* r1332 fix F5/F8 zero timeout handling in GetBiosKey
* r1331 some config.txt / contrib.txt updates merged from UNSTABLE
* r1330 fix Turbo C compilation: nls.* adds ASM/CDECL nlsInfoBlock
and makefile uses "$(COMSPEC) /c if exist" in UPX handling
* r1329 UPX compress kernels below 64k as .sys, save 2k disk space
* r1328 process relocations before compressing kernel, save 130 by
* r1327 use more flexible exeflat UPX trailer from unstable branch
* r1325-1326 new IRQTEXT segment, put pre-boot interrupt vectors
at 70:100 so int 19 reboot with JEMM386 "fastboot" can work
(see r1341, r1343: this introduced a later fixed problem...)
* r1324 add SHARE driver/TSR for file locking to main SVN branch
* r1323 fix bug 1956: use segment, not offset, for file handle NULL
check - otherwise apps which allocate their own FILES can break
* r1322 fix problem with old game which uses findfirst attrib 77a8
(do not return volume label as findfirst/findnext result here)
* r1320 add some comments about what intr() does
* r1319 read partitioning via CHS (unless Cyl>1023 / LBA forced via
SYS CONFIG) for better compat with old boot managers like "PROT"
* r1318 avoid compile time warning with OpenWatcom 1.7 in-devel
* r1313 call_nls optimization: ID in high word of long, no pointer
* r1312 always set lr.ES just before break, so OW can tail merge
* r1308 avoid OW 1.6 warnings about functions redeclared as static
* r1307 fix OW warning about comparing unsigned int to <= 0...
* r1306 NUL device has to return 0 bytes for reads even in raw

+ changes merged from Tom's extra stable fork of kernel 2035a:
* r1321 only move EBDA if ramsize == peek(0, RAMSIZE)
* r1317 extra free of near f_nodes to avoid INT24 problems
* r1316 remove unused intr prototype for resident code,
add dir kernel.exe to build process, cosmetic p=A -> p = A
* r1315 set OEM name in boot sector to FRDOS5.1 (5 uppercase
letter, 4 or 5, dot, digit: Win9x seems to like that better...
* r1314 implement int 2f.4a00 "DJ style" floppy change call
(let GUIs hook "Insert disk..." dialog on single floppy systems)
Some forgotten bits of int2f.asm NLS related updates
* r1311 optimized method to set extended error (smaller)
* r1310 use a command table for IOCTL, save ca 83 bytes

+ these changes are already in FreeDOS 1.0 kernel 2036cvs Aug 18 2006:
* r1305 build system adjustments - suppress dos4g banner etc
* r1304 fix MS QB4 (QBasic/QuickBasic) problem, allow double free
(freed MCBs are unlinked from the chain but not invalidated)
* r1303 only use 28 bits of FAT32, mask out others, add logging
* r1302 add COMn/AUX func 6 (input status), remove read wait for DSR
2006 May 20 - Build 2036 cvs and 2037 test
-------- Eric Auer (eric@coli.uni-sb.de)
WARNING: This changelog entry is a draft! The cvs log contains
data for both HEAD and UNSTABLE branch while a cvs checkout
seems to return only the HEAD branch. This file history.txt
should describe "2036 cvs" HEAD and "2037 test" UNSTABLE
separately rather than in one merged changelog item.
In addition, the "Changes Eric" items yet have to be ported to
the UNSTABLE branch and the version.h for UNSTABLE should say
"03 Mar 2006" "2037 test" (revision 37)...!
Most recent changes to source code (see version.h) are:
HEAD 9 Sep 2005 (not counting the Korean stub and execrh change
by Eric, and not counting the version number change itself)
UNSTABLE 3 Mar 2006 (includes SYS changes, more Win3 support,
COM port output for debug print, the SHARE tool...)
The head to unstable diff in general is quite large. As a rule
of thumb, use UNSTABLE if you need NLSFUNC or Win3 386 mode or if
you need a very new kernel, and use HEAD if you need stability.
+ Changes Jeremy
* build.bat, config.b: UPX and WIN3 build options, for BUILDALL
* boot/oemboot.asm: set backup boot sector on FAT32, add update
option, fix oemboot to work with msdos 7+, in UNSTABLE branch.
* docs/bugs.txt: update Bugzilla URL
* docs/config.txt: document SWITCHES, based on suggestions from Eric
* docs/contrib.txt, docs/fdkernel.lsm: new email address
* docs/sys.htm, docs/sys.txt: see oemboot.asm
* docs/sys.txt: better check for valid backup boot sector # and add
option to skip setting it
* hdr/debug.h, kernel/prf.c: slight cleanup, send debug prints to COM
port, allow printf to work correctly when SS!=DS, debug changes
* hdr/device.h: add comments about what flags mean
* hdr/portab.h: from dev: add MK_PTR and MK_SEG_PTR macros
add/use halt() wrapper for issuing "hlt" asm instruction
* hdr/version.h: update version to 2035b-cvs (= not a release yet)
* kernel/config.c: fix read calls to detect error, from Eric / Brad
* kernel/console.asm, newstuff.c, prf.c, task.c: compile time option
to send debug output to COM port ("serial debugging console")
* kernel/dosfns.c: do not compares filenames to name field in block
devices, extra win3 support, misc debug output changes, IsDevice
should not compare filenames against block device driver headers
* kernel/dsk.c: works towards better SS!=DS support, centralized
debug macros, some comments
* kernel/entry.asm: more win3 support, debug output changes, comments
* kernel/execrh.asm: protect 386 registers, using hdr/stacks.inc
macros (Watcom: FS, GS Others: high 16 bits of EAX EDX, for MSCL8
also ECX, for BC5 also EBX), for ALL device driver calls. Without
this, some versions of free-EMM386 crash 386 optimized kernels.
See list archives 24 Jul 2005 and later.
* kernel/fatfs.c: don't leave fd open when failing DIR bit check
bug 1874 fix, do not consider setting DIR bit an error for
int 21/4301=set attribute, if really is a directory
Added some disabled debug messages, improved win3 support.
* kernel/init-mod.h: allow printf to work correctly when SS!=DS
* kernel/initdisk.h: insure bpb_huge is initialized (zeroed) [merge
from dev kernel], fake floppy ddt so hd access works correctly on
floppyless systems, based on suggested fix from Eric
* kernel/int2f.asm kernel.asm main.c: initial BIOS disk int 13h wrapper,
only passively detects and notes floppy disk change, more win3 support
* kernel/inthndlr.c: potential fix for spurious near fnodes!=0 msg with
shsufdrv and >2 near fnodes in use for bug 1879, use halt() wrapper,
more win3 support, some debug output changes.
* kernel/intwrap.asm: assembly glue to wrap misc interrupts with C
handler, cleaner push immediate from Arkady and note big bug to be
fixed, later moved to UNSTABLE branch (also affects makefile)
* kernel/proto.h: fix prototype, add FAR
allow printf to work correctly when SS!=DS
* mkfiles/generic.mak: undo a local only change, build list option
is proper way to do this. more win3 support, upx build option.
* mkfiles/watcom.mak: allow printf to work correctly when SS!=DS
* share/MAKEFILE, share/share.c, share/share.hlp: FreeDOS SHARE
(initial revision, later moved to UNSTABLE branch)
* sys/fdkrncfg.c: sync printf prototypes (uncorrupt executables)
* sys/sys.c: sync printf prototypes (uncorrupt executables)
better check for valid backup boot sector # and add option to skip
setting it. set backup boot sector on FAT32, add update option,
fix oemboot to work with msdos 7+
+ Changes Eric
* kernel/globals.h changed the os_release version message to be
"build 2036 cvs [version Sep 09 2005 compiled May 20 2006]" as
opposed to the old
"version 1.1.35 (Build 2035b-cvs) [Jul 23 2005 12:34:56]"
-> removed the "1.1.35" and compile TIME, added SOURCE DATE
* hdr/version.h removed some no longer used version defines
Changed build to "2036 cvs" (revision 36)
WARNING: Version should be "2037 test" (revision 37) for UNSTABLE!
* docs/history.txt: summarized log -d '>Feb 25 2005' kernel for this
WARNING: some of the described changes might be available only
in the UNSTABLE cvs branch (like SYS OEMBOOT, Win3, COM port
output for debug print, the SHARE tool, ...)
* kernel/execrh.asm: removed the "protect 386 registers" patch
again, a fixed version of free-EMM386 is available. This reduces
device driver call overhead in terms of CPU and stack usage.
Older EMM386 versions destroyed eax ebx ecx edi esi ebp fs gs,
now go_driver_entry in emm386.asm saves those registers. Only the
INIT was broken, but the execrh.asm patch protected ALL functions.
* share/share.c: changes to reduce TSR memory footprint
* kernel/inthndlr.c: added stub for function 0x6301/0x6302 Korean
Hangul keyboard input methods (0x63xx is DBCS support related)
* docs/intfns.txt: updated list of supported DOS functions. When
DOSLFN is loaded for int 21.71, only remaining unsupported int
21 functions are 21.4b05 (set execution state), int 21.63xx
(DBCS / Korean Hangul, see above) and int 21.5d01 - 21.5d05
(close files by name/computer/task, list open files, commit all)
* made linebreaks in all batch files use CR LF, as Unix line breaks
confuse command.com, leading to "early abort" or "endless loop"
+ Changes Lucho
* kernel/chario.c: Fix Ctrl-Z bug and retro-optimise a bit
* kernel/config.c, sys/sys.c: Fix BC 3.1 CONFIG.C compile and
SYS Abnormal Program Termination error for BC
* sys/sys.c: fix update option (compared too many characters)
+ Changes Eduardo
* kernel/config.c: fix Spanish (34, not duplicate of 33)
* kernel/inthndlr.c: add int 2f subfunc 122B and 122D
+ Changes Jason
* kernel/fatfs.c: extended DPBs and Set Extended Error function
* kernel/inthndlr.c, kernel/proto.h: same
+ Changes Arkady
* kernel/inthndlr.c: use direct access instead of reading from copy
made on stack
* kernel/intwrap.asm, kernel/kernel.asm: cleaner push immediate from
Arkady and note big bug to be fixed
+ Changes Michael
* share/share.c: bugfixes
+ Changes Japheth
* share/share.c: HXDOS related improvements
+ Changes Bart
* kernel/main.c: patch to make device=f:\foo.sys work. String printf
optimisation
2005 Feb 25 - Build 2035a
-------- Jeremy Davis (jeremyd@computer.org)
+ Changes Bart
* int2f.asm: call_nls: DI register was not preserved (bug 1812)
+ Changes Arkady
* floppy.asm: fix epilog for FL_SETMEDIATYPE & FL_SETDISKTYPE
to use 'ret' instead of 'ret 8'; improve comments
* entry.asm: use unsigned comparision instead of signed
+ Changes Lucho
* dsk.c: text in play_dj
* fatfs.c:
- zero creation/access stamp on directory entry write as MS-DOS 7.10
- prevent removal or renaming of the current directory of that drive
* ioctl.c:
- r_si/r_di contents added as documented in PC-DOS Technical Update
* inthndlr.c
- fix: for INT21/5F07 and 5F08, before changing bit CDSPHYSDRV,
MS-DOS checks if physical device associated with drive letter. Without
this check MS-FORMAT under FreeDOS was destroys RAMDISK.
- zero serial number of Int 21h/30h (else buggy 32RTM thrashed stack) [& Bart]
- set AX = ES after Int 21h/4Ah (undocumented but expected by BRUN45)
(the last 2 changes needed to fix bugs discovered by Michael Devore)
- added Int 2Fh/2Fh processing to set DOS version as per MS-DOS 4.0
+ Changes Eduardo
* inthndlr.c: added Int 2Fh/26-29h processing for NLSFUNC (with Lucho)
2004 May 30 - Build 2035
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Lucho + Tom
* config.c, fatfs.c, globals.h, init-mod.h: From Tom: must
set r_bpfat for C_BLDBPB, otherwise USBASPI.SYS, DI1000DD.SYS
won't like us. From Lucho: use DiskTransferBuffer for deblock_buf.
+ Changes Lucho
* docs/fdkernel.lsm, stacks.inc, version.h,
entry.asm, inthndlr.c, io.asm, nlssupt.asm: no need to preserve
high part of ecx for Borland, ebx for MSVC
* device.h, dsk.c, init-mod.h, ioctl.c: MSC fixes and small cleanup
* ioctl.c: Cache attr and control flow optimizations (~120 bytes)
* device.h, dsk.c, ioctl.c: deal with the correct
structure for generic and query ioctls. Fixes issues with
3rd party device drivers (or ones that use dsk.c)
* dosfns.c, inthndlr.c, proto.h: Merge dosmkdir and dosrmdir
* config.c: strcasecmp and set_strategy common code optimizations.
* main.c: Add necessary cast for BC
* portab.h: Avoid problem with BC declaring __emit__, en/disable twice.
* dsk.c: DJ mechanism without memcpy.
* newstuff.c: replace loops by fmemset/fmemcpy (43 bytes)
* dosfns.c, fatdir.c, fcbfns.c, ioctl.c: Some small cleanups.
* config.c: GetNumArg and misc other cleanups
* time.h, fatfs.c: converted TM_ENCODE into a function.
* inthndlr.c, proto.h, fatfs.c: Inlined dos_setdta.
Various bug fixes and cleanups from Lucho and Arkady.
* inithma.c: moved fmemcmp's into a checkHMA function.
* inithma.c: HMAFree == 0xfff0 - bytesToAllocate
is valid and may happen if the buffers occupy exactly all HMA
space up to and including the last byte at ffff:ffff. Failing
caused all buffers to go low ...
* inthndlr.c: cleanups (merge common code into long_check and
short_check). Made int21/3301,2e,54 consistent with MSDOS
behaviour.
* globals.h, task.c, main.c: Convert setvec into a function
for the resident code
+ Changes Arkady
* initdisk.c: initdisk optimizations (65 bytes) and is_suspect fix.
* config.c, init-mod.h, intr.asm: optimized allocmem()
* fattab.c, kernel.asm: optimizations
* main.c: Make signon one big printf function call.
* ioctl.c: bugfix for INT21/440b (change NetRetry if DX is _non_zero).
* inthndlr.c: cntry == 0 doesn't make sense for Set Country
Information. Fix int21/5e02+
* sys/talloc.c: Turbo C really wants unsigned __brklvl. Only shows
up if you enable stack checking.
+ Changes Bart
* memmgr.c, proto.h, inthndlr.c: DosUmbLink no longer
tries to merge free blocks. Also cleaned up a bit.
* inthndlr.c: Fix int21/3302 (the swap was wrong, Lucho & Bart)
* config.c: Pointer-ise specificCountriesSupported accesses.
* config.c: Reorganized GetBiosKey a bit -- inlining
GetBiosTime saves a slight amount of code, converted timeout < 0
to a blocking read instead of polling.
* config.c: Use strcaseequal instead of strcasecmp since we
never care about order anyway.
* chario.c: Fix problem with redirected input and
int21/ah=0a (debug < foo.txt) -- could get you an invalid opcode!
* console.asm, main.c, prf.c: Use int29 for kernel console
output. Enables ansi escape sequences in config.sys once you load
nansi.sys. It also saves a couple of bytes.
* newstuff.c, proto.h: made dosmktmp to return a long:
consistent with DosOpen et al and avoids the cast.
* mkfiles/tc2.mak: Let TC2 warn for the utilities.
* config.c: Disabled EBDA moves by default. Automatic EBDA
moves now happen using switches=/e:-1
* config.c: Pointer-ize MenuStruct[MenuSelected]... (from
Lucho). and InstallCommands[i]. (from Bart). Some other small
optimizations.
* memmgr.c: Some small optimizations (46 bytes) and dead
code removal from Lucho and Bart
* init-mod.h: Need to define strchr to init_strchr otherwise
the wrong one may be called.
* initdisk.c: Do a bit of printf merging.
* filelist, drivers/makefile, init-mod.h, inthndlr.c,
task.c, globals.h, main.c: Convert getvec into a C function.
* int2f.asm: Clean up int2f assembly a bit (merge some
common bits, clarify label names)
* fatfs.c, fattab.c: fattab.c now remembers if the old FAT
entry was free or not, so the free space adjustment could be
moved back to fattab.c.
* init-mod.h: Replaced setvec macro by a function.
* entry.asm, inthndlr.c: Made int21/ah=25,35 reentrant.
Solves problem with Intel PRO/1000 driver.
* portab.h, globals.h, main.c: Initialise all int
vectors except the ones at 70:xxxx using a table. Convert setvec
into a function that disables/enables ints (init code only for
now, resident code will follow later); cli/sti (disable/enable)
are now macros (inlined).
* fnode.h, fatdir.c, fatfs.c: dir_read() no longer updates the
diroff counter. This eliminates the NEW field,
simplifies remove_lfn_entries(), and avoids a bug if you delete
the first entry in the root directory on FAT32.
* fattab.c: Stop abusing "idx". The OW optimizer likes this better,too.
* fattab.c: Clean up FAT12 handling -- there's a portable
approach that's small too.
* fattab.c: Inlined much of getFATblock() into link_fat.
Saves the idx reference. The second call (for a FAT12 entry that
is divided in two sectors) can be much simpler, no need to
recalculate. Merged next_cluster and link_fat into one
function depending on a special Cluster2 value.
* fattab.c: Calculate the nibble/word/dword index of the FAT
entry in the sector centrally in getFATblock.
* fattab.c: "clussec" can be of CLUSTER size if we divide by
an adjusted "words per sector"(FAT16), or "dwords per
sector"(FAT32) value instead of multiplying it first. For FAT12
the *3/2 works out a little differently: here we first multiply
by 3 and then divide by the number of "nibbles per sector".
* main.c: Config.cfgInitTail is a pointer now so sizeof
isn't good. Just using strcpy helps F5 and F8.
* main.c: "copyright" is near now so we have to use %s and not %S
* blockio.c, dosfns.c, int2f.asm, network.c, proto.h, task.c:
reduced the number of network redirector functions in
int2f.asm. The remote_ functions (with one far pointer
argument) are now called with the help of a
network_redirector() wrapper in C by one multiplex function
using a generic void *arg argument to pass the third
parameter which can be various things.
Split int2f.asm functions, don't let them preserve as many
registers, use pascal calling convention for the "open"
(but really: multiplex) function.
* dsk.c: floppy determination type optimization for format --
based on Arkady's suggestions a long time ago.
+ a few other small optimizations (~70 bytes total).
2004 Apr 17 - Build 2034
-------- Bart Oldeman (bart@dosemu.org)
* break.c, chario.c, inthndlr.c, proto.h: Improve ctrl-c/ctrl-break
handling:
- read_char_sft_dev handles ^C at a fairly high level.
- ^C didn't work for int21/ah=3f. Corrected
- Do_DosIdle_loop still needs to wait even if it doesn't call the
idle int
- ^C needs to be echoed to STDOUT for low character functions
(ah<0xd) but to the device that is read from for handle
functions. So we need to pass either the STDOUT sft or that
device on to the ^C echoer which now correctly prints ^C\r\n.
- misc cleanups in break.c.
* main.c: Move memset up a little else it would overwrite too much.
* build.txt, config.c, init-mod.h, initdisk.c, inithma.c, main.c: Lucho
reported that MSC compiled kernels now work after all. Let's mark
those nasty "BSS" variables explicitly then to try to avoid
future problems. Also DATASTART should be FAR and not DOSFAR for MSC
* stacks.inc, generic.mak, entry.asm, int2f.asm, kernel.asm, segs.inc:
(suggested by Arkady): use CPU to enforce 8086 etc instructions.
* ioctl.c: Correct int21/ax=4401: returned AL = old value, should
set CY and DE_INVLDDATA if DH!=0 (RBIL is a little confusing here).
* memmgr.c: Converted nxtMCBsize back to a macro. There is no need
to use far2para; FP_SEG works fine since MCBs always have offset 0.
* build.txt, config.c, config.h, kernel.asm, main.c, segs.inc, task.c:
Removed obsolete BYTE cfgCSYS_fnam[NAMEMAX]; config variable. Changed
cfgInit and cfgInitTail to pointers, adjusted some code to cooperate.
* chario.c: The screen position (for TABs) is only for raw
*CONOUT* devices already updated in dosfns.c
* memmgr.c, proto.h: Make unnecessary far pointers near.
* device.h, dsk.c, initdisk.c: Move the ddt bitfields to
df_descflags. Let SetLogDev call GetLogdev, eliminating common code.
* init-mod.h, mscl8.mak: Some vars need to be DOSFAR;
init code is no longer tiny but small.
* segs.inc, inithma.c, main.c, asmsupt.asm, execrh.asm, init-mod.h,
kernel.asm, watcom.mak:
Make CS the same for INIT and HMA text for Watcom. Move HMA text
up in kernel.asm. Use std for the memory move: helps if there's
overlap (PCs with a very low amount of RAM).
No longer include duplicate execrh, asmsupt, and u8m/d functions
for the init text in the Watcom compiled kernel, since they can
be called "near" in the resident code.
* portab.h, kernel.asm, main.c, segs.inc:
Use the "small" model for the init code (split code/data).
* main.c: Use pointer to MK_FP(0,0x5e0) to save a bit of code.
* initdisk.c: Move some common code into a "push_ddt" function.
* sys.c: Correct int25/26 pragmas. Need to explicitly preserve bp
and pop flags.
* initdisk.c: fmemcpy->memcpy where possible
* config.c, init-mod.h, inithma.c, int2f.asm: Make
UMB_get_largest "pascal". Let it use the xms driver address from
the HMA code. Misc small config.c cleanups.
* initdisk.c: "Cache" far drive data table near. Enables elimination
of many far pointers in initdisk.c. Also clear up the
unnecessary casts in ConvPartTableEntryToIntern.
* drivers/getvec.asm, drivers/rdpcclk.asm, drivers/wratclk.asm,
drivers/wrpcclk.asm, globals.h: Use pascal calling
conventions for all clock related asm functions.
* drivers/floppy.asm, dsk.c: Use pascal calling conventions
for floppy asm functions.
* init-mod.h, intr.asm, proto.h, kernel.asm: Use the
pascal calling convention for all intr.asm functions, and let
them pop the stack (smaller code than using bx). Tell Watcom
which registers are clobbered; save some more registers for
intr() -- especially for intr() this helps.
* device.h, execrh.asm, init-mod.h: Use pascal calling conventions
for execrh().
* mkfiles/watcom.mak: Use the "-r" switch for Watcom to preserve ES
around calls -- saves ~350 bytes.
* sys.c, init-mod.h, fdkrncfg.c, portab.h, prf.c, proto.h:
Introduce VA_CDECL: only Turbo C 2.01 needs an explicit cdecl
for printf, all other compilers can use it with pascal or
"register" calling conventions. Saves ~50 bytes for the init code.
* asmsupt.asm, config.c, init-mod.h: Use strchr and strlen
more often; also use strchr in the init code.
* memmgr.c: Better to call fmemset than to do things manually.
* asmsupt.asm, proto.h, init-mod.h: Be more specific about
which registers are clobbered by asmsupt.asm functions. Preserve
"ES" for Watcom. Saves ~150 bytes resident, ~90 bytes
nonresident, more for 386 kernels.
Preserve bx and cx for WATCOMC as well. Saves another 200 bytes.
* inthndlr.c: Simplify memory access mode check.
* dsk.c: Remove wrong "512" value for number of root directory
entries on FAT32 partitions.
* file.h, sft.h, dosfns.c, fcbfns.c: Get rid of SFT_M* mode
values. O_* values are sufficient.
* file.h, fatfs.c: Define O_ACCMODE and use it instead of "3" for
the open access mask.
* config.c, init-mod.h: Change default STACKS= size to 256.
* config.c, init-mod.h, main.c: Remove lpOldTop variable.
It is no longer necessary (has not been for some time) and the
assignment in config_init_buffers() was wrong (screwed up fnodes,
so that buffers overlapped fnodes...).
* lol.h, config.c, fatfs.c, globals.h, kernel.asm, proto.h:
Made the main fnodes far so they can be in the HMA.
Internally the kernel uses two near fnodes though, to save on
codesize and fmemcpy's if necessary. Having memory management on
two fnodes is a little silly but I just want to make sure with
the panic message that we never accidentally try to use three near
fnodes at the same time (two are used at the same time by rename,
commit, and merge_file_changes). This can be cleaned up later.
* fatfs.c:
- Merge three almost identical pieces of code used to allocate a new
directory entry in creat, rename, and mkdir into alloc_find_free.
- Merge find_fat_free() and extend() -- they were almost
identical. Have a simplified clause for f_cluster ==
FREE. Set f_cluster = FREE in shrink_file if the file is set to
0 bytes; in that case we should set the current cluster to FREE
even if it is currently a LONG_LAST_CLUSTER.
* fnode.h, fatdir.c, fatfs.c, lfnapi.c:
- Eliminate f_back field. extend() now uses f_cluster instead of
f_back, while map_cluster makes sure it's not set to
LONG_LAST_CLUSTER (but to the cluster before it) when calling
extend(). extend() and first_fat() now return the new cluster
number or LONG_LAST_CLUSTER, just like find_fat_free().
- Eliminated f_sector and f_boff fields from fnodes.
- Avoid bitfields for fnodes, using flags instead. Replaced droot
field by checks for f_dirstart == 0.
- Make f_diroff an entry offset so it can be 16bits. Enforce the
65536 entry limit in dir_read(), except for root directories.
For root directories it's checked against a different limit
later. Saves 80 bytes or so + 2 bytes in every f_node.
* dsk.c, fatfs.c, memmgr.c: Remove add_far. adjust_far can do the job.
* chario.c: Echo input LF as CR-LF unless it's the first
character. Never store LF in the buffer.
* memmgr.c, task.c: Eliminated long2para and avoided use of "long"s
in DosExeLoader, using paragraphs to measure size instead. Saves
~130 bytes together.
* prf.c, asmsupt.asm: Saved ~75 bytes in printf and by elimination of
fstrlen. There's only one call; inlining doesn't increase the size.
* dosfns.c, int2f.asm, intr.asm, nls.c: Eliminate intr()
from resident code. Saves ~200 bytes of HMA resident code. Also
made the nls.c functions SS!=DS safe.
* init-mod.h, inthndlr.c, intr.asm, main.c, proto.h, task.c:
int21/ah=26: new_psp now copies the old psp and just sets a few
fields int21/ah=55: child_psp does the rest init code does the
init (fixed values are always copied now)
* dosfns.c: Commit each close, even if the ref count is > 0.
* prf.c: Borland C didn't like one pseudo register use.
* initdisk.c: Merge "suspect partition" copy/paste code into functions.
* asmsupt.asm: Save a couple bytes by moving the strncmp_retzero block.
* fcbfns.c, proto.h: Don't call truename from FcbNameInit(). It
was only necessary for "FcbRename", which can call it itself.
Fixes for FcbOpen/FcbFindFirstNext a consequence of
truename's funny behaviour: truename(c:nul) = c:/nul and
truename(c:/nul) = c:\nul. Fixes the EJECT problem from Lucho.
Remove unused variable lpFcb.
* portab.h, dsk.c, main.c, newstuff.c: Define I386 and I186 more
cleanly. Add (UWORD) casts to silence the compiler. Optimize
(head*sector) to secs_per_cyl. Add BORLANDC to compiler list
and simplify startup printf to one message.
#pragma enable_message(130) for Watcom C causes it to
behave a little more like Borland in terms of warnings.
* exeflat.c, fatfs.c, fattab.c, fcbfns.c, inthndlr.c,
memmgr.c, task.c, blockio.c, fatdir.c: Added explicit
(UWORD) type casts to avoid compiler warnings and sometimes save
a few bytes too. Also changed the FcbParseFname return value:
returns offset portion of pointer (SI) instead of the number of
bytes to be added to SI.
+ Changes Lucho
* task.c: fixes the CHKDSK I: "Invalid drive specification" bug
* mcb.h, inthndlr.c: save 33 bytes by eliminating a switch for
memory/UMB access modes.
* talloc.c: talloc won't work with MSC (no sbrk or brk available)
+ fix
* stacks.inc: smaller Protect/Restore 386 register macros.
* inthndlr.c: Code size reduction and dead code removal.
* dosnames.c: Remove wrong automatic "*.*" code from Lixing
Yuan -- return DE_PATHNOTFND or D_NFILES instead
* ioctl.c: move the lock/unlock simulation of success before the
device GENIOCTL check so that it applies to any device.
* filelist, dosnames.h, dosfns.c, dosnames.c, fatdir.c, fatfs.c,
globals.h, init-mod.h: (with Bart) -- remove the dosnames path
67 length check. Review the places where it really matters (chdir
and mkdir).
* init-mod.h, intr.asm, kernel.asm, main.c, procsupt.asm,
proto.h, task.c: enable interactive re-execution of the SHELL.
* nls.h, config.h, globals.h, init-mod.h: move NLS #defines to
nls.h. Move config structure to config.h. Some cosmetic changes.
* contrib.txt: From Lucho: update contributors list.
* config.c: From Lucho: fix EBDA problems with INSTALL. This
fixes the weird fmemcpy lockup; in reality kernel init code was
overwritten.
* asmsupt.asm, config.c, init-mod.h, inithma.c, main.c, makefile,
prf.c: Use asmsupt string and mem functions for the init code too.
+ Changes Arkady
* task.c: A few suggestions. Saves 5 bytes.
* inthndlr.c: Use AL, not AX, for int2f/ax=1213, as per RBIL
* inthndlr.c: Use xreg struct and macros to optimize the
int2f/12,4a handler a bit ~25 bytes
* config.c: Buffer config fixes.
* inthndlr.c, proto.h: Corrections to int2f/ax=4a01/2.
* blockio.c: buffer intersection check should use > instead
of >=. small optimization -- the segment in bp == firstbuf is
always the same so we just need to compare offsets.
AllocateHMASpace needs to check FP_SEG(firstbuf) for 0xffff,
since the buffers may not live in the HMA.
* *.bat, config.b, kernel/makefile, generic.mak: .BAT file and
makefile cleanups. Also Lucho reported that nmake/nologo doesn't
always work in 4dos, but nmake /nologo works.
2004 Jan 31 - Build 2033
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Bart
* config.c: allow "0" in full-screen config menus and plug a
few potential related overflows.
* sys.c: correct sectors/track, head and hidden sector values
if the boot sector disagrees with the default bpb (unless the
default bpb says that the number of hidden sectors is zero (usual
for floppies)).
* config.c, main.c: Only put PATH= in the environment if
it's still empty just before executing the shell. This repairs
SET PATH=.... in config.sys without confusing anyone.
* fatdir.c, fatfs.c: Fixed bug #1722: dir_close() was
called for normal files (via map_cluster and find_fat_free). This
completely messed up rwblock. Removed these calls (for
directories they are already covered at a higher level) and added
a few sanity checks to dir_close and dir_write.
* chario.c, inthndlr.c: Expand tabs for int21/ah=2,9 even
in raw device modes and if stdout is redirected. This solves bug
1737 (grep2msg problem)
* ioctl.c: Adapted from Chris Rodie's patch for bugzilla
#1730: do a device input status request for int21/ax=4406 for
devices (not for files). Save ~100 bytes by replacing
s->sft_flags with flags, s->sft_dev->dh_attr with attr and
simplifying the if() statement a bit
* hdr/sft.h, dosfns.c: Adapted from Chris Rodie's patch
(bugzilla #1729): "open" and "close" should call the open/close
functions for devices using a device request when appropriate.
* hdr/fat.h, fatdir.c, fatfs.c, fattab.c, prf.c, proto.h:
+ FAT32 kernels should ignore the upper word of the cluster
number for FAT16 partitions (just like FAT16 kernels do)
+ added extra checks to make sure that invalid FAT entries are
never followed
+ print a message in case of FAT corruption
+ some small optimizations and header cleanups (some suggested by
Arkady)
* config.c: Make strupr code unambiguous
* filelist, sys/makefile, sys/sys.c, sys/talloc.c: ~1K size
reduction for sys.com by using Tom's talloc.c malloc/free
functions and using our own filelength for watcomc.
* initdisk.c: Better (for FAT32) and simpler FAT default
value calculations. Also use 16-bit instead of 32-bit quantities
where possible to save code size. Use a FAT32 table so that FATs
won't be too big for drives <= 64 GB
* dosfns.c: Do not clobber the DTA if findfirst or findnext fails.
Fixes bug #1712
* fatfs.c: Rename blockio by rqblockio (namespace conflict with dsk.c)
* inthndlr.c: FAT32 kernels should fail int21/ah=71 with
al=0, carry set.
* hdr/portab.h, nls.c: (as reported by Tom) Fix nls upcase problem
with SS!=DS.
* fatfs.c: Move permission check to better place (only for
necessary for opening existing files), not for creating them --
suggested by Steffen. Force r/o open for FCB and legacy creat
if the file is read-only
* fatfs.c: Move common code in media_check() to a new
blockio() function.
* fcbfns.c, globals.h, inthndlr.c: Change FcbReadWrite to
handle multiple records at once; this allows for the optimization
of FcbRandomBlockIO.
* fcbfns.c: Divide optimisation (ceiling) + some small cleanups
* fcbfns.c, globals.h, kernel.asm: Rename the global lpFcb
variable to sda_lpFcb. Then use local lpFcb variables where
necessary. This clears up the confusing shadowing.
* fcbfns.c, inthndlr.c, proto.h: Fix FCB problems with
int21/ah=27,28 (RandomBlockIO)
* boot32.asm: jmp -> jmp short (necessary for nasm 0.98)
* dosfns.c, inthndlr.c, proto.h: Implement support for
int2f/ax=1220. Fix int2f/ax=1216 (needs sft handles, not psp
handles, and to return the relative handle in BX, and to deal
with carry)
* boot.asm: Fix problem with FAT12
+ Changes Eric Luttmann <ecl@users.sourceforge.net>:
* main.c: Fix for multisegmented device drivers: If there are multiple
device drivers in a single driver file, only the END ADDRESS
returned by the last INIT call should be the used. It is
recommended that all the device drivers in the file return the
same address. This fixes a load problem with DUSE.
* config.c, init-mod.h, main.c: fix for multi-segment device
drivers; preserve rq_endaddr between init calls for the same driver.
+ Changes Lucho:
* inthndlr.c: Remove AL=0 check for AH=6c (from Arkady) Optimize DL check.
* main.c, serial.asm: (with some help from Tom):
initialize serial ports and retry serial reads on timeout.
* sys.c, boot.asm, boot32.asm, boot32lb.asm:
SYS 3.0 changes: added /L parameter to SYS to be able to change
the kernel boot segment + a few boot sector changes to get the
pointer at the same magic place for all boot sectors.
* makefile: clean up *.lnk files for "clean" and "clobber".
* dsk.c: the DJ mechanism needs to affect MEM 0050h:0004h - MS-DOS
LOGICAL DRIVE FOR SINGLE-FLOPPY SYSTEM (A: / B:) Size:BYTE
* int2f.asm, generic.mak: basic implementation of INT 2F/ax=4a33 -
CHECK MS-DOS VERSION 7; necessary for SpinRite (Steve Gibson)
* inthndlr.c: implement int2f/ax=1211 NORMALIZE ASCIZ FILENAME
* config.c, init-mod.h, main.c: Added SET support to config.sys
2003 Sep 24 - Build 2032a
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Bart
* fix segment problems with ctrl-c and character uppercase
handlers
* fix critical error callers to set the critical error code
immediately before calling the handler (in case they call
DOS-59); don't set the critical error in inthndlr.c if
something else already did. Return with an errorcode if
"truename" and "read"/"write" encountered a critical error.
* sys.c: add /k kernname.sys option to and straighten out SYS option
processing; remove the metakern magic.
* config.c: ignore the segment part for multi-part device drivers
2003 Sep 21 - Build 2032
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Rune Espeseth <re@icd.no> (modified by Bart)
* config.txt, config.c: Full screen config.sys menus (use MENUCOLOR=)
+ Changes Michal Bakowski (mb@orad.pl)
* initdisk.c, kernel.asm: Change the boot drive to always
be C: if DLASortByDriveNo==1
+ Changes Arkady
* dsk.c: Use memcpy instead of fmemcpy; avoid downcasting
from far to near.
* sysclk.c: err if sizeof(struct ClockRecord) != rp->r_count
move year init below reading the BIOS
* main.c: init_device corrections/cleanups
* device.h: Change r_status and dh_name to unsigned quantities.
* task.c: Free memory if there is an error in the relocation
table.
* floppy.asm, getvec.asm, rdatclk.asm, rdpcclk.asm, wrpcclk.asm:
driver .asm files optimizations (also from Bart); remove
obsolete rdatclk.
* build.txt: Fix some typos.
* inthndlr.c: Add missing (); small optimization for DosGetdate/time.
+ Changes Lucho
* boot.asm, boot32.asm, boot32lb.asm, sys.c: add metakern support:
sys looks for a file metakern.sys which is a multiple of 512.
* break.c: Fix ctrl-break bug.
* ioctl.c: IOCTL 4406 provided reverse AL output on regular
files - FF if EOF, 0 if not. It should output 0 if EOF, FF if not.
* initclk.c: Initclk changes
* config.c, init-mod.h, initoem.c: Support for
switches=/e[[:]nnnn] and for moving the EBDA
* fatfs.c: Use 0x10000UL (avoids Turbo C warning)
* sys.c: Move manually added "RCS" entries to the CVS log.
* main.c: Adjustments for MSVC.
* ioctl.c: int21/ax=440d lock/unlock logical/physical volume
simulate success for MS-DOS 7+ SCANDISK etc. --LG
* main.c: && should be || in check for \, / and :
* task.c: Adjust registers used when starting programs. Some
demos expect undocumented values (with Bart).
* mscl8.mak: Forgotten HMA_TEXT for MS compilers.
* sys.c: Add lock/unlock drive to SYS
* history.txt: Changelog correction.
* fatfs.c: Use near bpb on the stack in bpb_to_dpb. Make
sure the number of FAT sectors is actually enough to hold that
many clusters. Otherwise back the number of clusters down
* procsupt.asm, proto.h, task.c: Don't disable a20 for
"exit" int21/ah=4c
+ Changes Lucho, Tom, Eric
* boot.asm, boot32.asm, boot32lb.asm, makefiles, sys.c:
* boot.asm modified to support non-512 byte sectors
(e.g. 1.2 MB NEC diskettes)
* 512 byte sector size check removed (although Eric's boot32ea.asm
does require 512-byte sectors, all LBA FAT32 volumes have
512-byte sectors anyway).
* boot.asm cleaned up and modified to support Metakern
bsDriveNumber updated by SYS even #ifndef STORE_BOOT_INFO
* (nothing in common)
* SYS Now supports and includes the following new boot sectors:
1) the combined CHS+LBA FAT12/FAT16 boot sector by Tom Ehlert(29 July)
2) the CHS-only FAT32 boot sector -- as patched by Jon Gentle(08 July)
3) the LBA-only FAT32 boot sector by Eric Auer and Jon Gentle (19 July)
* The old combined (CHS+LBA), no-CALCPARAMS, no-resizable, non-Ghostable,
non-standard FAT32 boot sector and STORE_BOOT_INFO is no longer used.
* dump_sector() showed ASCII debug printout for the old sector
only - fixed.
* Put a boot sector only if sector size= 512 (may it not be so in
Japan?!). If non-512 byte sectors encountered, report to the
fd-kernel mailing list.
* Now puts boot sector before copying kernel/shell so it works in
WinNT now.
* check_space() now implemented at last (required significant
modifications)
* New (FAT type) detection method according to a MS White Paper.
* Now BOOTONLY works even without preceding boot sector image file name.
* Some minor code cleanups.
* Bart: some cleanups to the above; replaced 386 code for CHS FAT32
by 8088 code. Use boot32lb.asm instead of boot32ea.asm
+ Changes Bart
* portab.h, process.h, init-mod.h, inithma.c, kernel.asm, main.c, task.c:
* add support for the far jmp at "int 30" (0000:00c0)
* mirror it for the HMA (ffff:00d0)
* put all DOS int handler (and the CPM entry jumped to from
int30) jumpers in the "CONST" portion of DGROUP (instead of
LGROUP) This helps Turbo C++ 1.01 make with the -S (swap)
switch.
* adjustments to set the relevant PSP fields in task.c
* blockio.c: Always use huge block sectors if the relevant bit is
set in the device header. This solves a problem with xmsdsk.
* chario.c: Small optimizations
* clobber.bat: Remove duplicate clobber.
* Flip some slashes for Linux compat and simplifications in makefiles
* device.h, portab.h: Use STATIC=static for watcom C (statics
are in the mapfile); remove some cruft.
* makefile, wlinker.bat: More verbose mapfiles for watcom
C; some slash preparations to allow cross-building on Linux
* exeflat.c, patchobj.c: Fix warnings reported by Turbo C
* break.c, chario.c, dosfns.c, globals.h, inthndlr.c,
proto.h, systime.c: (with a little help from Arkady)
Simplifications and cleanups.
Pass a near pointer to the far pointer that points to the device
instead of an SFT index (in general).
Make cooked_write much faster by only testing for input every 32
characters. No longer test for ctl_s on syscon if writing to
the printer: just read from the printer which will return zero
characters. Fix reading/writing zero characters by returning
"256" (special code). Adjust interfaces in other files.
* portab.h: New UNREFERENCED_PARAMETER macro that appears to
work for all compilers.
* floppy.asm: Remove unused code.
* init-mod.h: Solve compilation problem with Borland C++ 3.1
* config.b: "-p" is no longer necessary in config.bat
* kernel.asm: Add necessary "BootHardDiskSeconds" for non
UPXed kernels.
* chario.c, dosfns.c: Add necessary casts to ? : constructions;
cleanup read_line_handle a little.
* portab.h: Add peek and poke #defines
* chario.c: Fix pointer overflow problem for reading line using handle.
* makefiles, exeflat.c Clean cleans a bit more; change () to (void)
* main.c: Set the PSP before the DTA. This solves an interrupt
vector table corruption.
* kernel.asm: Use "local" (instead of "global") disable/enable
A20. This solves the problems with NIOS.
* asmsupt.asm, misc.c, proto.h, strings.c: Remove (unused) strncpy.

* add Bulgarian country structure data
+ Changes Bart

* combine the INIT class with the CODE class (classes can span
multiple physical segments)
* re-add _TEXT to LGROUP to be able to simplify the patchobj magic

* config.c, main.c, portab.h
implement INSTALL and INSTALLHIGH for config.sys
basic COUNTRY=xxx support (with a little help from others,
mentioned in config.c)
* execrh.asm: save si, di for strategy device driver handler

+ Changes Tom
* move clock driver initialization to inittext
* new ELSE_ISFAT16 macro to save some bytes
* use _TEXT for old HMA_TEXT, _LOWTEXT for old _TEXT to get

* move all old RCS log messages into one seperate file
* divide the fnode f_cluster_offset field by the size of a cluster:
this gives a more efficient map_cluster().
* point the CharMapSrvc pointer to the DOS DS for AARD compliance.
* nls.c: set CX to cooperate with load_unf.exe
2002 Nov 9 - Build 2027
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Tom
* memset ErrorAlreadyPrinted to 0 in config.c
+ Changes Bart
* reset drive before and after int26 in SYS for winnt compatibility

2002 Oct 27 - Build 2027rc
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Bart
* reorganized chario.c, got F1-F6, Ins, Del, etc. working
* fixed bug in extended open
* fixed bug in memory manager (realloc should try to defragment;
UMB fixes)
* consistently pass sft_idx around for all SFT functions (instead of
the far pointer)
* lpUserStack is gone :)
* Idle interrupt: now uses disk i/o stack instead of error stack if it
re-enters DOS; can not be called from int21/ah=3f. It also checks
InDos now (as documented in "undocumented dos").
* int21/ah=59 should use the disk i/o stack, not the character stack.
* get_cds: a uniform way to get the CDS for drive X which can do error
checking too. get_dpb: similar.
* task.c uses mid-level system file handles instead of PSP handles.
* SFT sequence is MS/DR DOS like: 0=AUX 1=CON 2=PRN
* int21/ah=4d needs to clear the return code after returning it.
* Removed need for "unusedretval" because some functions return a long int
now.
* Do not warn for some additional LBA partition layouts (begin/end
cylinder=1023) in initdisk.c.
* support int2f/ax=1213 (uppercase character) (ASCII only for now).
* fix for top of memory parameter to device driver - fixes problem
with DRDOS emm386
* eliminated printf for non-init code -- use put_unsigned and
put_string instead
* better MK_FP for Turbo C++ 1.01 and later
* PSP related task.c cleanups
* use --best and new upx (1.23) for binary build
Changes Tom and Bart:

* set the number of sectors per track in the INT 1E table when
reading/writing floppies

brain-dead exepacked programs.
* removed unnecessary "BUFFERS" fields
* proper check for network/non-existing drive for int25/26.
* save more bytes on the stack at various places
* made the local registers for inthndlr.c "near" instead of "far".
* fix bug in strchr handling for fcbfns.c (FcbParseFname)
+ Changes Steffen (but changed a lot by Bart)
* new truename (Bart: but without mapPath() style struct)
* merge open/create functions into one extended open function
* also honor the sharing bits better for "open"
* use local 8+3 path names in fatfs.c; merge name+extension
into one array
* take care of filenames that start with ASCII 5: they should be
treated as starting with 0xe5
* exploit the fact that the filenames are already "truenames",
i.e., fully qualified in fatfs.c. This simplifies parsing a lot.
+ Changes Bart
* make "if exist c:\dir\nul" working
* honor "do not inherit handle on exec" flag for "open".
* improve the FCB functions so that they set the critical error code
properly
* next_cluster returns "1" instead of DE_xxx in case of failure.

driver and character drivers such as CON)
* better handling of ABORT/FAIL
* merge all read and write functions
* patchobj makefile correction
* printf uses va_list etc.
* quicker and more robust Watcom build
* use FS: and GS: for Watcom 386.
* workaround: don't use DL for floppy boots, but fixed A:
* disable unused functions in floppy.asm
* cleaner prototypes (thanks to gcc)
* reorganized ioctl.c; there was an uninitialized variable.
* inlined some functions of fattab.c
* added (f)strcmp, (f)memcmp and (f)memchr to asmsupt.asm
* initially suggested by Arkady: dsk.c FS_info copy optimization
* initialize a VDISK signature in the HMA
* sysclk.c: small size optimization
* small UMB fixes
* made the CDS into a proper array instead of a structure with
one member
* large task.c cleanups -
merge as much as possible from DosExeLoader and DosComLoader
(from Tom:) eliminate some structures in low memory
* main.c: slightly cleanup "SHELL=" line parsing.

does not feature a changeline
* reset to root directory when floppy has changed
* cleaned up endian helpers {get,put}{byte,word,long}
* don't close file if disk is full
* enforce minimum of 9 sectors per track for INT1E (necessary for
some floppies on some XTs)
* clear carry when calling INT23 (ctrl-break handler) as per RBIL
* don't copy FCBs on exec if they are pointed to by FFFF:FFFF.
* resolved warnings for Watcom (now compiles with -wx -we)
* truename fix (return DE_FILENOTFND for foo.bar.foo)
+ Changes Jeremy

+ Changes Tom
* set CONFIG environment variable to selected number of CONFIG.SYS
menu entry, for example for use in AUTOEXEC.BAT.

the redirector is safer than setting CF
* allow creating, renaming and deleting volume labels using FCBs
* fix renaming with wildcards using FCBs
* some dosfns.c and fcbfns.c clean-ups
* booting from hard disk now always sets the default drive to C:,
not D: if booting from the second physical hard disk, etc (bug #1062).
2002 Feb 9 - Build 2026
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Tom
* fixed various typos, #includes
+ Changes Bart
* fixed ECHO in config.sys
* made passing parameters to command.com more robust:
zero commandline before use, fixed buffer overflow for F5+F8
* "uppermem_root" in the List of Lists is now FFFF if no UMBs
available, as documented in RBIL
* removed all direct hooks from init_text to hma_text; duplicated
the remaining functions (memset, memcpy and friends).
* bumped up default DOS version of FAT32 enabled kernel to 7.10
2002 Feb 3 - Build 2026test
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Tom
* FCB clean-ups and fixes (bug in FCB Random IO,
CYRUS CHESS, bug #1014)
* initial config.sys menus (see config.txt)
* execrh.asm: construct 'interrupt' address after strategy to avoid
some issues with non-trivial 'strategy' routines.
* make kernel UPX-able
* cleaned up midnight flag, dates
* tmark() and friends are floppy specific and implemented in C
instead of ASM (parts by Bart)
* DMA boundary checking gives the right number of sectors if
the start sector is 512-bytes-aligned.
+ Changes Victor

* FAT32 fixes
* dosemu log nicer
+ Changes Martin
* log output
* warning fixes for sys, patchobj and prf.c
+ Changes Bart
* FCB clean-ups and fixes

* implement commit file (int21/ah=68,6a)
* implement ioctl get/set logical drive map (int21/ax=440E--F)
* implement get address of drive data table (int2f/ax=0803)
* fix "get address of SDA" (int21/ax=5d06)
* do not use CHS if the root extended partition of the relevant
logical partition is labelled LBA (bug #1011)
* hopefully avoid format problem (bug #1030) by not setting drive
to "non-accessible" while reading the bpb.
* boot sector fixes:
enable booting beyond cylinder x where x * number of heads >= 65536.
still uses CHS to boot (not able to boot beyond cylinder 1023)
recognize FF8-FFF as FAT12 ending (was only FFF) (bug #1021)
* avoid using LIB when linking the kernel by echo-ing to a linker
resource file. Use a batch file to bypass Borlands Make 2.0
unwillingness to redirect stdout.
* UMB variable clean-up
* use of "const" for constant global variables
* reduced size of Watcom-compiled SYS binary
2001 Nov 18 - Build 2025c

2001 Nov 17 - Build 2025b
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Tom
* fix a few more batch file and makefile details
* fix problems with command line editing: F1 and right key
* string merging in dosnames.c
* optimizations for MSC
+ Changes Bart
* fix readblock problem not properly detecting EOF - it sometimes
returned an error where it should just report a short count.
Also fnp->f_offset==0 is not a special case for blockread
(neither should it be for write - but that'll be for later)
For both cases it's perfectly legal to do a seek first.
* fix writeblock not setting highwater to offset when doing a
truncate (count == 0)
* hopefully now really fix the floppy change problem -
dsk.c: getbpb() should query changeline BEFORE reading the BPB.
* fixed warnings from WATCOM compiler - one of them was in fact
a bug in fcbfns.c
* started big clean-up
- converted obsolete bcopy(), sncopy() and friends to memcpy(),
strncpy() etc.
- removed $Log entries that are also on the CVS server and
removed the $ so no new entries will be added in files.
indenting will be next - other fixes will be buried in diffs if
I do that now.
2001 Nov 12 - Build 2025a
-------- Bart Oldeman (bart@dosemu.org)
+ Changes Tom
* initialize LBA parameter struct to 0's - some BIOSes don't fill
in everything. Thanks to Bernd Blaauw's bug report.
* Minor boot sector optimization.
* added some exeflat options
+ Changes Jeremy
* changes to fdkrncfg.c: mostly cosmetic to the output
* added sys.doc file (updated by Bart)
+ Changes Bart
* let int 0 (divide by zero) and int 6 (invalid opcode) print a
stack trace to aid in debugging
* fixed floppy drive detection for XT's.
* fixed bug in int21/ah=0x32 and friends - we should flush data before the
forced media_check
* Use CHS addressing if possible on partitions with the relevant ID,
you can overide this using the new FORCELBA and GLOBALENABLELBASUPPORT
sys config options.
* Always use BIOS values for translating LBA to CHS for fixed disks -
ignoring the boot sector values. For floppies the boot sector is used.
* fixed "truename hello." to remove the trailing dot.
* added options to SYS to write to a boot sector image file
* set Critical Error Code for ioctl's
* fake cluster size for 64k clusters just like FAT32 for INT21/AH=0x36
and friends.
+ Changes Bart+Tom+Victor
* make makefile system more robust
+ Changes Victor
* cleaned up map_cluster and dir_read (bug fixed by Bart)
* updated LFN API (in development, not used yet)
2001 Nov 4 - Build 2025a (test)
-------- Bart Oldeman (bart@dosemu.org)
+ Changes tom
* config.sys processing: placing ? on the left side of '=' like
?device= or device ?=
asks for this single line
fill the available HMA with buffers
* added kernel configuration options to sys.com, small area at 60:xx
(in cooperation with Jeremy)
* readblock optimized to read as many data as possible in one
int13 request - great speedups for large reads
* some more SDA variables need to be updated for the network
redirector (the sft index)
* reduce stack usage in task.c, fattab.c, ioctl.c, execrh.asm, inthndlr.c
* protect high part of 32-bit registers (stacks.inc)
* moved copyright messages to init data to save a bit of memory
* added relocinf, patchobj, sorted + some more output of exeflat
* UMB fixes
+ Fixes Bart, Victor, Tom
* more FAT32 fixes - to work with device drivers
* fixed overflow problem with more than 2048 directory entries
* various space saving changes, dir_init_fnode
+ Changes Bart, Tom
* many makefile changes to enable compilation with different
compilers (MS, Watcom, Borland). Watcom compiles but the result
does not run yet.
+ Changes Bart
* extended the double-byte lead table from int21/ah=63 to 4 zeros
to make Watcom happy
* support for IOCTL AX=440D, CL=40,41,42,61,62 for
read/write/format track - this enables R. Nordier format to work
* default floppy type depends on the drive
* rewrote many parts of int2f.asm to have a cleaner remote_xxx
interface with less code and stack usage.
* limit for int21/ah=36 is FFF6 total/free sectors
* made the rtc clock reading code a bit more robust - assumes
there is no rtc if the returned date is zero
* removed non-necessary code in dosnames.c because we're always
dealing with a TRUENAME there
* added zero extending of files, but removed it (unless you force
it) since MSDOS doesn't zero-extend files either
* wrote a source for exeflat, removed all binaries from the source
* added more INT2F/AH=12 functions to solve some MSCDEX issues
* changed BAD sector handling : only ....FF7 is recognized as BAD,
but FORMAT information from initdisk will only give ....FEF as
the largest cluster (for safety), so ....FF0-....FF6 are not used
for newly formatted disks (here .... is either nothing, F, or
FFFF, FAT12/FAT16/FAT32).
* more fatfs/fatdir clean-ups - now unnecessary fields dfull,
dremote and dsize removed from fnodes.
2001 Sep 24 - Build 2025

+ Fixes Victor
* More FAT32 fixes

(look for play_dj() in dsk.c)
* Simplify Victor's FAT32 fixes a bit
* More printer clean-ups
* fixed sys (thanks Jeremy)
* DosChangeDir fails for path name too long.
+ Fixes Jeremy
* Changed SYS so if no source given or only source drive (no path)
given, then checks for kernel.sys & command.com in current
path (of current drive or given drive) and if not there
uses root (but only if source & destination drive are different).
Fix printf to include count(ret) if copy can't write all requested bytes
2001 Sep 22 - Build 2025 (test)
-------- Bart Oldeman (bart@dosemu.org)
+ Added Victor
* FAT32 support (credits to Martin Stromberg for boot32.asm optimizations)
* Delete long file names if short file name given
+ Added Jeremy
* modified SYS so it takes optional 2nd parameter (similar to PC DOS)
where if only 1 argument is given, assume to be destination drive,
but if two arguments given, 1st is source (drive and/or path)
and second is destination drive
+ fixes Victor
* some small FCB and dsk.c fixes
+ fixes Tom
* some FAT32 issues
* many compiler portability changes (compiles with Watcom, MSC, ...)
* DosMemChange should set the PSP
* converted INT2F/AH=12 functions to C and added some - enough to
get most of the MS LAN network client working
+ fixes Bart
* some FAT32 issues
* Dos{Open,Creat}Sft drive letter issues
for CDROMs (thanks Jeremy)
* shrink_file should ALWAYS fail for directories, also with
dos_set_fattr (thanks Jeremy)
* only give warnings for slightly suspect partitions at boot
time where CHS does not match LBA.
* re-enabled copyright notice.
* some dsk.c clean-ups to avoid DIR giving the same contents for
a different floppy (get serial number/volume label did reset the
changed state).
* attribute should be 8-bit fix

* fixed get current directory - MSCDEX works now (always)
* initdisk.c correctly sets number of hidden sectors: necessary
for FORMAT - SYS chain to work
+ updates Bart
* initialisation memory situation changed: kernel is loaded
to the top of conventional memory in the beginning. Then
move it back low or high depending on DOS=HIGH and the presence
of an XMS driver.
DOS=HIGH without an XMS driver (such as FDXMS) has no effect anymore!

* task.c: copies default FCBs, initializes AX properly and
an int21/ax=4b01 fix. Also closes all FCB opened files upon
termination of a program.
* dosnames.c: fixed DJGPP "ls c:/" problem reported by Martin
+ fixes Victor Vlasenko
* Makefile fix for dealing with Borland make 3.6
* fix for fatfs.c shrink_file()
+ fixes Bart
* handle B: just like A: on a single floppy system. There still needs to be
user interaction like "Please put a floppy in drive B:".
* ioctl.c fix for INT21/AX=4400 + sft driveno field
* various small fcb fixes
* put file position number and pointers to Pri/SecPathName into
SDA. Now MSCDEX works as redirector (but still not always :-()
* redirector set attribute fixes + various cleanups
* truename+attr+ioctl fix => DJGPP libc compiles cleanly!
+ changes Bart
* use the output of truename() consistently: this saves a lot of
headaches in parsing later and also allows a lot of simplifying:
made many parameters in fatfs.c and fatdir.c NEAR
+ added Bart
* partly implemented the "Drive Data Table" see RBIL INT2f/AX=0803
* implemented construction of default BPB in initdisk.c
* implemented the access flag in dsk.c
* printf writes to DOSEMU log if prf.c compiled with #define DOSEMU
+ fixes Bart
* dsk.c uses default BPB in the right places (with help from Tom and Brian)
* Brian's FORMAT now works
* Tab fix (bug reported by Martin Stromberg)
* INT21/AH=0x1f now simply uses AH=0x32 for the default drive
+ fixes Tom
* saved some static variables
* implementation of int_2f_111e_call() for network/LAN manager
* return AX=0001 for default redirector handler
* enable use of multiple UMBs
* fixed task.c 'LOADHIGH executables': minAlloc == maxAlloc = 0
and an fixed overwriting the MCB
2001 Jul 9 - Build 2024/d
-------- Bart Oldeman (bart@dosemu.org)
+ fixes Bart:
* fixed Ctrl-C (Ctrl-S and Ctrl-Q still missing).
* ioctl EOF fix (DJGPP less&gdb problem reported by Martin Stromberg)
* INT21/AH=29 (Parse Filename into FCB) fix (NC problem reported
by Ken Martwick) with clean up from Tom.
* ioctl should do a media_check before calling the block driver:
this fixes bug #726 (first dir gave serial no. 1234-5678).
* initdisk.c now uses the init data segment.
+ fixes Tom:
* fixes for INT21/AH=32; this should cure the problems with
Brian's new format.
* more SYS fixes.
+ added Tom:
* some more diagnostics (123) to aid finding bugs when booting from
a hard disk.
from 2001 jun 23 : KE2024BP
+ fixes Tom:
* FAT FS: would not expand files correctly, if lseek()
beyond EOF (see also relnotes.txt)
* FcbFindFirst/Next made compatible with MSDOS CHKDSK
* saved even more bytes (now 24 buffers in HMA :-)
from KE2024BM
+ added Tom:
* a mechanism, to regain near data (like miarray, bpbarray,...)
this is somewhat braindamaging, moving the kernel up and down,
working with different CS/DS combinations, but somehow working, :-)
miarray allocated, using this mechanism.
* made f_nodes near (2 K saving in HMA_TEXT)
this technic might as well applied to CDs, DPB, sft's, ...
this even saves a few bytes on stack :-)
from 2001 May 21: Build2024L
+ Fixes Tom:
* Clustersize 64K made working (one small ULONG was missing)
* check for drive existence for INT25/26
* NDEV = max number of possible harddisk partitions bumped
from 8 to 20 (my testconfiguration has 13)
+ Added tom:
* LBA support for disks > 8GB (with the help from Brian
Reifsnyder, see also relnotes.txt)
* moved initialization for DISK (partition scanning) to INIT_CODE
2001 Jun 2 - Build 2024
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes Tom:
* small fixes again.
* one possible cause for data corruption (BFR_VALID) detected
* directories with 'ARCHIVE' attribute could not be deleted
* saved even more bytes (now 20 buffers in HMA :-)
* some issues with pathnames around PARSE_MAX removed
* blanks in filenames weren't proper handled
* there was (at rare circumstances) a buffer overflow
while config.sys parsing.
+ Fixes Bart:
* INT 21 0A - Dos Buffered Input reworked
* init_PSPSet() fix for setting the PSP
+ Added tom:
* slighly better buffer handling (search BFR_UNCACHE)
now go more FAT+DIR sectors, less DATA sectors into cache
* dos_mkdir tuned (was ~0.5 sec on 64K cluster partitions)
2001 Apr 29 - Build 2024
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes Bart:
* fixed the "TYPE > FOO.TXT" poor man's editor.
* use "fast console output" (int 29) when applicable.
* moved 5 FILES to DOS DS:00CC and fixed the SFT linked list.
* cleaned up findfirst/findnext for redirected drives.
Tom:
* more VDISK changes (changed slightly by Bart)
* check for presence of A:/B: (changed by Bart to use the BIOS equipment flag
from INT11 instead of INT13).
* added F5/F8 stepping through config.sys; default SHELL=COMMAND.COM /P/E:256
Use ESC to stop single stepping, F5 to skip remaining config.sys/autoexec.bat.
* new sys: uses INT25/26 instead of the low level INT13 related kernel code from
floppy.asm (see also comments in sys.c) + a few fixes (also boot.asm related)
from Bart.
* Hopefully fixed DateTime Changed + ATTRIB |= ARCHIVE bug.
* cleaned up dsk.c and saved more bytes.
Przemyslaw Czerpak:
* Default lastdrive should be 5 (E) not 6 (F).
* fixed not ignoring whitespace after '=' in config.sys
* noted INT21/AX=3800 bug for getting the country. Put in a workaround for now.
2001 Apr 21 - Build 2024
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes Tom:
* fixed a missing close_dir in fatfs.c.
* many reductions of stack space requirements.
we hope this fixes some FAT corruption problems.
Bart:
* fixed "copy con" and INT21/AH=0B. The SFT_FEOF flag,
strangely enough, if true indicates NOT end-of-file.
* VDISK signature required in HMA (bug 701 dborca@usa.net).
Alan Kamrowski
* fixed intr: it wasn't putting the flags back correctly
and swapped si and bp.
+ Update Bart:
* Changed initialization data segment to its code segment.
This frees up a few more kb.
* This required some header reorganisation:
init-mod.h is for the init modules, globals.h for all the
others.
* Eliminated the master environment, as it is normally
managed by command.com, not by the kernel. This saves 512
bytes and command.com now copies a default environment from
0068:0000; this is in the DOS_PSP at 60:0.
* Moved low memory code segment to 70:0.
+ Add Tom:
* Default interrupt 6 handler (invalid opcode).
2001 Apr 16 - Build 2024
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes * Use turboc.cfg to avoid long command lines; edit ALLCFLAGS
in config.mak to enable DEBUG etc.
* Fixed critical error handler.
* Fixed loading .exe's in UMBs if not enough space available.
* Some device drivers require \r\n at the end of their
parameter line.
2001 Apr 16 - Build 2023
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes * Thanks to Martin Stromberg for pointing some bugs out:
* more warnings fixed.
* accidentally opened too many file handles at boot time.
* device drivers should not be linked into the device chain
if they do not take up memory.
+ Add * added printf "%S" and "%Fs" to print far strings.
* enabled and cleaned up INT21/AH=6C (extended open/create).
2001 Apr 15 - Build 2023
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes Tom:
* apisupt.asm not necessary anymore.
* fix warnings.
* Don't allow directories to be created in DOS_CREAT.
* LoadDevice: drivers should not hang the computer if they fail.
Bart:
* fixed SYS.
* made most calls near again, with a jump/stack trick to
switch between INIT_TEXT and HMA_TEXT.
* INIT_TEXT now calls INT21 itself for some things (setting
PSP, opening/reading/closing devices and (fd)config.sys).
* fixed some carry handling in inthndlr.c and
* drives are checked before trying to access them.
* fixed console driver "busy state" confusion: the built-in
driver had it wrong, nansi.sys had it right:
"If no characters in buffer, return BUSY".
* space savings (RTL related and various other places)
* redirector fixes for find_next.
* CREAT on a device file failed (FD said it already existed).
But for some reason it should not fail in DOS.
* get ATTRIB/other things on a device file should return
FILENOTFOUND, not PATHNOTFOUND.
The sft_status field is not used for redirected drives.
* DosSelectDrv checks the media before setting the default
drive.
* Fixed INT21/AH=3,4,5 (character R/W AUX/PRN).
Hans Lermen:
* critical error handler destroyed AH (entry.asm).
Martin Stromberg
* find_first for volume labels fix.
* check drive at more places and avoid drive "@:" for drive "':".
* config.m: comment out NASM= by default.
* printf fix with DEBUG on.
+ Add Tom: Introduce init_data segment.
New temp file creation implementation.
Bart: added INT21/AH=53. XMSDSK works fine now.
dynamic allocation of Drive Parameter Blocks (they are
all FAR now).
+ Update Bart: moved DOS_PSP to segment 0x60 as segment 0x50 is already used by
GWBASIC/BASICA
2001 Apr 2 - Build 2023
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes Bart: Volkov Commander revealed a few bugs:
-int 21/ah=55 forgot to set current psp to child psp.
-memory allocation: mem_access_mode was a signed byte, and hence 0x80 was
translated to 0xff80 and not 0x0080 when converting to a COUNT. Hence
changed it to become a UBYTE.
-An error in memmgr.c: search again in low mem for modes 0x80,81,82, not
0x40,0x41,0x42
* execrh.asm & int2f.asm: made code executable on a 8088 (no push
constant)
* entry.asm: made sure dos_crit_sect is executed when required to.
* Another redirector fix. int 2f/1122 needed DS=current psp. This caused a
bug for me: after compiling FreeCOM on a redirected drive "dir" did not
work any more.
* The nansi.sys problem: as it was, the initialisation phase of nansi
called int/ah=30, which checked control-break, which checks the console
driver, which at that point is the still not initialized nansi. This
messed up the request header passed to it. A solution I found is to link
a device into the device chain _after_ initialisation, not before.
* Redirector fix: network.c uses fmemcpy instead of fsncopy.
* Fixed INT 21/AH=6 (direct console input).
Tom:
* DE_NFILES instead of DE_FILENOTFOUND to allow Volkov Commander to browse empty
drives.
* Fixed bug wrt zero terminated device names (should be spaces terminated).
2001 Mar 30 - Build 2023
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes Tom: Kernel alloc initialises to 0. This avoids some weird errors.
Implemented default divide by 0 handler (INT 0)
FILES= fixes from config.sys. fatfs.c ignored it and always
used the default of 16.
Misc debug code removal.
int 21/ax=3306 report running HIGH fix.
int 21/ah=69 : save CX
InitializeAllBPBs() or MakeNortonDiskEditorHappy()
More extended information if MCB chain corruption occurs.
Bart: getdpb fixes (int 21/ah=32).
fix carry handling in int 21/ah=5e.
fix {get,set}_machine_name in network.c
saner lastdrive handling
+ Add Support for SHELLHIGH in config.sys
2001 Mar 28 - Build 2023

+ Fixes sys.com compilation: it is a proper .com and works again.
Suggestions from Martin Stromberg: warning removal and some
debugging related changes.
Suggestion from Aitor Santamaria Merino: implemented NUMLOCK=ON/OFF
in config.sys. Also implemented strcasecmp.
Updated intfns.txt; reported version is now 5.0.
2001 Mar 24 - Build 2022
-------- Bart Oldeman (bart@dosemu.org)
+ Fixes Tom and Bart: cli/sti handling and other fixes in entry.asm,
procsupt.asm and apisupt.asm.
Bart: warning removal + other compile time fixes.
Tom: * more partition detection fixes in dsk.c.
* dos_gettime() fix.
2001 Mar 21 - Build 2022
-------- Bart Oldeman (bart@dosemu.org)
+ Clean A lot of space savings by Tom Ehlert, merely because Turbo C 2.01 does not
do it. And several more complicated situations as well, like coding some
string functions in assembly (asmsupt.asm).
+ Add Tom Ehlert: support for DOS=HIGH. Now most of the kernel can be loaded into
the HMA. This required a lot of segmentation changes. Let's hope the best
of it. Support for device drivers with multiple devices.
+ Fixes From Tom Ehlert:
task.c bug fix (image_size is in bytes)
dosfns.c change dir to E:\FREEDOS\*.PRJ fix
fcbfns.c fixes.
break.c Ctrl-C Ctrl-C -> crash temporary fix.
+ Fixes From Bart:
Let UMBs work again after HMA changes.
Be able to compile sys.com again. Is now really a .exe file but still masks
as .com in the hope that we can make it a real .com again.
DeviceHigh loads low if there are not enough UMB's available.
Fixed another redirector problem.
+ Update Optimized asmsupt.asm a bit with help of the glibc 2.2 source.
+ Fixes Tom Ehlert and Brian Reifsnyder: fix partition detection in dsk.c +
other bug fixes (also: floppy.asm).
+ Update Tom Ehlert optimized blockio.c.
+ Fixes a few small ones from Tom I forgot.

object footprint 3k smaller (Tom Ehlert)
Fix handling of very long path names (Tom Ehlert)
FindFirst/FindNext fixes (Tom Ehlert)
Configuration for libm.mak is in config.mak (Martin Stromberg)
NLS fix to include pointer to CharMapSrvc. Note: these are
changes to automatically generated .asm files, but the
generator (GRAB_UNF.EXE) is missing. (thanks Tom Ehlert)
DosSelectDrv fix (Martin Stromberg)
config.c always converts to upper case and handles dos=umb correctly
2000 Dec 15 - Build 2022

-------- James Tabor (jimtabor@infohwy.com)
2000/08/12 22:49:00 Ron Cemer (roncemer@gte.net)
Fixed writeblock() to only use getbuf() if writing a
complete sector; otherwise use getbloc() and do a
read-modify-write to prevent writing garbage back
over pre-existing data in the file.
This was a major BUG.
2000 Aug 05 - Build 2021

command using Dosemu Lredir. Fixed Dosfns return for ReadCount,
WriteCount and DosGetFattr. Fixed the return in int2f.asm for
Read/Write Remote. By adding xor ax,ax.
I found some more return bugs in int2f.asm after adding Barts
patch.

Code Clean up and Now the Release.
2000 May 26 - Build 2020
-------- James Tabor (jimtabor@infohwy.com)
+ Fixed IsDevice is used in FcbFns.c and DosFns.c. I removed IsDevice
from DosNames.c an placed it in DosFns.c. FcbFns had dup code
and it was removed. This fixed all the functions using IsDevice.
Truename works now. I consider it dangerous and brain damaged.
Note:
truename X:\DIR\con -> X:/CON, note the '/'.
truename foo*.* -> X:\DIR\FOO?????.???
truename *.*\*.*\*.* -> ????????.???\????????.???\????????.???
truename *.*\*.**\*.* -> endless Loop
I will fix this later ;^)
Found InitPSP running 3 time. On the 2'nd run the standard handles
were closed with out DosClose. Now Device Drivers can Print out

2000 Mar 25
-------- Eric Biederman
+ Fixed Lastdrive handling
+ Fixed Not enough drives for number present devices
+ Added Working (though not perfect network redirector)
Note: Error codes internal to freedos are negative
Error codes external to freedos are postive.
The network redirector is external to freedos...
Note: Running the nonredirected functions on a redirected
drive is dangerous. My patch is very careful
not to. Except in truename. Where (a) it is safe
and (b) I think it is required, and (c) it is needed
by dosemu.
2000 Mar 19 - Build 2019
-------- James Tabor (jimtabor@infohwy.com)
* Jean-Francois <lozevis.jeanfrancois@free.fr> email noting
the set/clear interrupt was reverse in order.
2000 Mar 17 - Build 2019
-------- Steffen Kaiser (Steffen.Kaiser@fh-rhein-sieg.de)
+ Fixed Config.c COUNTRY= statement
+ Fixed *.c to call upFMem() when upcasing filenames
- Removed everything to load NLS into memory
= Redesigned hardcoded NLS information
--> The kernel will now return the proper information for the
hardcoded NLS (U.S.A. / CP437), it would return the correct
information for other NLS, too, if there would be a NLSFUNC
available, which is not at this time.
NOTE: The way the external NLSFUNC is called does not look well,
therefore expect a change soon.
2000 Mar 15 - Build 2019
-------- James Tabor (jimtabor@infohwy.com)
* Dennis Newbold and Massimo De Munari email kernel bug reports
with changes to Globals.h and Inthndlr.c. Fix to leap year and
Delete file return code.
* Michal Meller found a bug in media_check. It return the wrong
value of sector count. Change in FATFS.C.
* Fixed Func 0x32 based on information from Marty <k3pbu@arrl.net>.
Func 0x32 Get Drive Parameter BLK did not work.
2000 Mar 09 - Build 2018
-------- James Tabor (jimtabor@infohwy.com)
Added CDS and made FD CDS based. Changes encompass all of the
code for FD.
Fixed Task.c, rewritten code from FINODE to SFT function calls.
Unable to execute from CD. Main.c and Config.c has small
changes.
Fixed Device drivers are unable to write to con. Rewritten code to
relocate DOS_PSP pointer to 050:0000. Removed references to
DOS_PSP in DosFns.c.
Added Network and Redirection function calls in Inthndlr.c and
network.c.
I have a note in FatFs.c line 313, describing functions not yet
supported for networking. I don't understand Pats thoughts on SFT to
FINODE. IMHO it would have been easier to stay with SFT all through
the code.
I tested MS-Dos 6.22 Command and found it unable to do Find First or
Next. This too could explain why MSCDEX does the same thing. I only
test this with the current FDCommand at the time, so this could have
changed.
1999 Sep 24 - Build 2017
-------- John Price (linux-guru@gcfl.net)
* Per Jens Horstmeier's email, changed boot sector code to make
Siemens CDROM's bootable. The changes should be OK for all other
machines too (in theory).
1999 Sep 22 - Build 2016
-------- John Price (linux-guru@gcfl.net)
* Turned off debug output from the kernel. It does not seem to be
necessary at this time.
* Changed boot sector to do single-sector reads instead of
multi-sector reads. Appearantly this was part of the reason the
kernel would not boot from a 720K, or other format floppies. Thanx
to Charles Dye for the info.
1999 Sep 16 - Build 2016
-------- James Tabor (jimtabor@infohwy.com)
* Added Networking and Server Call
* Added Dos Idle call
* fixed Console.asm ConInStat
1999 Sep 13 - Build 2014
-------- John Price (linux-guru@gcfl.net)
* Deleted some files from the drivers directory that were not being
used.
* Changed the LIB.MAK file so it would work for TC2 or TC3 or higher.
* Changed SYS.COM so that it creates a sys.log file with more debug
information to help debug problems with making boot disks.
1999 Sep 13 - Build 2014
-------- James Tabor (jimtabor@infohwy.com)
* Submitted changes to CONSOLE.ASM & INTHNDLR.ASM to fix the INT21
func 0B bug.
1999 Sep 13 - Build 2014
-------- Helmut Fritsch (helmut.fritsch@gcd-hs.de)
* Submitted changes to CONSOLE.ASM to fix the INT21 func 0B bug.
1999 Sep 10 - Build 2014
-------- ror4 (f2xm1@crosswinds.net)
* At the suggestion of Mr John Price, modified the int 0x25 and int
0x26 so that they no longer update the disk buffers (int 0x26 only
invalidates the buffers for the specified drive). This is to avoid
inconsistent disk buffers from appearing in the buffer chain due to
interactions between int 0x25/0x26 and file read/write operations.
1999 Aug 24 - Build 2013
-------- John Price (linux-guru@gcfl.net)
* With ideas from ror4, I redid the build batch file so you can
specify where what make to use.
* Also created CONFIG.M and CONFIG.B which should be copied to
CONFIG.MAK and CONFIG.BAT, respecively, and edited to reflect the
users configuration. This keeps new versions from replacing the
configuration files so the user does not have to keep reseting
their configutation.
1999 Aug 15 - Build 2013
-------- ror4 (ror4@angelfire.com)
* Patched the source so that it can be compiled with Turbo C 2.01.
(`asm' statements were rewritten into very ugly equivalents... they
probably need more work. :( )
* Modified the `dmatch' structure in `hdr/dirmatch.h' so that the
`dm_dirstart' field is in the right place, and also to make it
compile under TC 2.01, which doesn't allow bit fields of any types
other than signed or unsigned int.
* Fixed a few minor bugs in error code returning in `kernel/fatfs.c'.
1999 Jul 16 - Build 2012
-------- ror4 (ror4@iname.com)
* Finally ported all the assembly modules to `nasm'. *phew*
* Undid plonee's patches to `kernel/fatfs.c' (sorry). They were
causing the resulting findfirst/findnext DTA structures to be
incompatible with MSDOS's.
* Also rewrote all the pattern copying code in `dos_findfirst' in
`kernel/fatdir.c' to prevent a bad buffer overflow problem.
* Modified the disk buffer handling code, so that logical sector
numbers in disk buffers are now 0-based instead of 1-based.
* int 0x25 and int 0x26 now do multi-sector reads/writes.
1999 Jul 14 - Build 2012
-------- ror4 (ror4@iname.com)
* Ported the modules in the `drivers/' branch to `nasm'.
1999 May 04 - Build 2011
-------- ror4 (ror4@cryogen.com)
* Fixed the code for converting day numbers into Julian calendar
dates: the first and last days of each month are now returned
correctly.
* Undid a change to the code to get the day of the week.
1999 May 02 - Build 2011
-------- John Price (linux-guru@gcfl.net)
* blockio.c: changed getblock and getbuf so that they leave at least
3 FAT type buffers valid. This helps because the FAT is accessed
very often compared to other sectors.
* fatfs.c: Fixed a bug in map_cluster so it will optimize FAT reads
on disks that have more than one sector per cluster. This
sigificantly improved disk access of big files on hard drives.
1999 May 02 - Build 2011
-------- ror4 (ror4@cryogen.com)
* Corrected the `struct buffer' definition in `kernel/globals.h' so
that it corresponds exactly to Ralf Brown's description of a DOS 3.x
buffer.
* Also fixed the problem with FATs > 255 sectors, by making use of an
originally unused field in the buffer structure.
1999 May 01 - Build 2011
-------- ror4 (ror4@cryogen.com)
* Fixed a problem which caused disk corruption on partitions with
FATs larger than 127 sectors. (However, FATs larger than 255
sectors may still experience problems -- this is due to a
limitation of the DOS 3.x buffering scheme.)
* Fixed a bug in the handling of the `stacks=' command in
`(fd)config.sys' which caused the system to behave strangely.
1999 Apr 22 - Build 2011
-------- Steffen Kaiser (Steffen.Kaiser@fh-rhein-sieg.de)
bugfix: memmgr.c: Invalid returned largest size in MemLargest()
fix: memmgr.c: DosMemLargest: change prototype to match its useage
bugfix: inthdlr.c: 0x49: ES is decremented
fix: inthdlr.c: 0x00: DosMemCheck() does nothing --> added panic()
fix: inthdlr.c: 0x4c: DosMemCheck() does nothing --> added panic()
fix: inthdlr.c: 0x00: changed to make it the same as DOS-4C-00
Both actions differed e.g. in ErrorMode
chg: memmgr.c: the 'name' field of the MCB is never initialized by
DOS-48, DOS-49 or DOS-4A. Leave this to the program loading function.
bugfix: memmgr.c: adjust_far() / add_far():
Both function together (and the way they are used) don't make sense:
adjust_far() normalizes a far pointer, add_far() generates a linear
address. Usually both are used this way:
far_poi = adjust_far(far_poi);
while(...) {
...
far_poi = add_far(far_poi, uword);
...
}
First one makes sure that 'far_poi' is normalized, then far_poi
becomes a linear address, which makes it very difficult to use
it, because the possibility to get a segment warp gets very high.
-->
Change: add_far() also returns a normalized real mode pointer
as adjust_far() does.
Probably in DOS-C supporting various architecures thee functions
served other duties, but the current useage is highly dangerous.
bugfix: task.c: ChildEnv(): nEnvSize didn't counted the last '\0'
bugfix: task.c: ChildEnv(): Allocation: maximum absolute filename to
short and forgot the word counter
bugfix: task.c: ChildEnv(): for very corrupt environments, the
copy function failed.
bugfix: task.c: DosExeLoader(): If exe_size > allocated_size or
DosMemLargest() failes, the environment is not deallocated
bugfix: task.c: DosExeLoader(): Calculating the exe_size to be
allocated. At both places (+ header.exMinAlloc & ...MaxAlloc)
sizeof(psp) is added to exe_size. Why? image_size already
contains sizeof(psp).
chg: task.c: DosExeLoader()/DosComLoader(): MCB patching and command
line copying is no outside of those functions
chg: asmsupt.asm: _fbcopy: re-use parts of _bcopy
add: asmsupt.asm: fmemset, fmemclr, fmemclra {Replace the explicit
for() loops}
1999 Apr 22 - Build 2011
-------- ror4 (ror4@cryogen.com)
* Ported boot.asm to NASM. The plan is to port all assembly to NASM
over time.
1999 Apr 19 - Build 2010
-------- John Price (linux-guru@gcfl.net)
* Undid the change I made to getblock below because it DID NOT speed
anything up, and in fact slowed access down.
1999 Apr 18 - Build 2009
-------- John Price (linux-guru@gcfl.net)
* change getblock so that it flushes all buffers for a drive when it
has to flush one of them to make room. This should speed disk
access slightly.
* Change the boot sector so there is a compile-time option to use
multi-sector IO or single-sector IO. The default is multi since
ror4 seemed to have fixed the problem we had before.
1999 Apr 18 - Build 2009
-------- ror4 (ror4@cryogen.com)
* The boot sector can now load the kernel properly from a hard disk.
* Other minor changes.
1999 Apr 16 - Build 2008
-------- ror4 (ror4@cryogen.com)
* Modified the block device driver to prepare it for multi-sector I/O
support. Among other things, the driver can now handle transfer
buffers which cross DMA boundaries.
* Some other minor changes.
1999 Apr 15 - Build 2008
-------- John Price (linux-guru@gcfl.net)
* Changed mainly the map_cluster function in fatfs.c so that instead
of starting at the beginning of the FAT chain every time, it will
be smart about it, and start at the last FAT location that it was
before if it can. This speeds up disk access considerably
especially on slower machines.
1999 Apr 15 - Build 2008
-------- Steffen Kaiser (Steffen.Kaiser@fh-rhein-sieg.de)
bugfix: ^Break handler according cmt1.txt
bugfix: DosCreat(): Detection for Devices and extension:
the semi-colon behind if(*froot) is definitely wrong, whether
one wants CON.EXT to be interpreted as CON or not.
bugfix: DosOpen(): dito
* Re-implementation of ^Break handler -- 1999/03/27 ska
+ Warning: The handle_break() function assumes that the InDOS flag
was incremented (except if ErrorMode is true). Never call
handle_break() unless the InDOS flag has been incremented within
this reentrant call of DOS.
+ ^Break is detected and handled at certain places within the
kernel only: a) within the CON: device when reading or writing a
character, and b) when entering the INT-21 service (if extended
break checking is enabled). At these places the process flow can
be modified to: either a) redo the interrupted function or b) abort
the currently running process.
+ Both actions are performed by switching back to the user stack
and enter INT-21 handler again. If to terminate the program, AX is
modified into 4C00h.
+ By default, if the user has no ^Break handler installed, the
program is terminated.
+ Heavy change: The original implementation installed an unique
INT-23 handler that directly called the actions performed
DOS-4C-XX. In fact, this was identically with when the user had an
own handler installed and returned the Carry flag set, except that
it was somewhat quicker, because the kernel need not decode the
4C00h command. Now the Carry flag is set prior the call of INT-23,
so the default action is to terminate the program.
+ Note: INT-23 is called with all registers as they are passed to
the INT-21 entry. When they are modified, they are passed
_modified_ to the API interpreter. This also allows the DOS1-style
termination by to load register AH with 0 (zero).
+ RBIL says:
"any DOS call may safely be made within the INT 23 handler,
although the handler must check for a recursive invocation if it
does call DOS"
This can be interpreted so or so, the problem is that the user can
call DOS again, what would overwrite the saved _usr_stack pointer
with a different value and, therefore, cannot be used to check if
INT-23 was returned by RETF or RETF2/IRET.
Because a recursive invokation of INT-23 is to prevented by the
user, the kernel could internally save SP to somewhere else.
However:
a) where?
b) is it reliable that the user ever returns from INT-23 at all?
The implemented method uses the same mechanism as fail-safe intr()
function is implemented: A little piece of code is constructed
within the stack, which contains the value of SP as an operand of
an immediate MOV instruction.
1999 Apr 13 - Build 2007
-------- ror4 (ror4@cryogen.com)
* The boot sector now moves itself to the last 512 bytes of
conventional memory instead of a lower memory location.
* The kernel startup code has also been modified so that it works
with the new boot sector.
1999 Apr 12 - Build 2007
-------- ror4 (ror4@cryogen.com)
* The directory scanning functions (`findfirst'/`findnext') now also
recognize more flavours of the volume label attribute byte (namely
0x09, 0x28 and 0x29).
* Subdirectories are now no longer assumed to have the same size as
the root directory.
* `device/device.lib' is now included as a dependency in the kernel
makefile.
* Removed several unused assembler modules from the `device/' branch
(see `device/device.mak').
1999 Apr 11 - Build 2007
-------- ror4 (ror4@cryogen.com)
* The kernel now reads times from the system clock (0x40:0x6c)
instead of the RTC. The RTC is only used during startup to
initialize the system clock. (As a side effect of this,
`ReadATClock' has been moved from `_TEXT' to `INIT_TEXT'.)
* Checking for leap years is now improved -- year numbers which are
divisible by 100 but not by 400 are not counted as leap years. (Not
that it matters for year 2000, though.)
* The scaling factor used to convert the system time count to a
second count has been changed from 18.2 to the more accurate (?)
19663/1080.
* Day numbers used by `clock$' are now 0-based (as in MSDOS) instead
of 1-based. Thus 1 Jan 1980 is now day number 0.
1999 Apr 10 - Build 2007
-------- ror4 (ror4@cryogen.com)
* Added code to prevent the kernel from returning path names
containing double backslashes.
1999 Apr 9 - Build 2007
-------- ror4 (ror4@usa.net)
* File handles are now cloned properly when a child process is spawned.
* The `DosClose' function now also frees SFT entries corresponding to
devices, not only those entries corresponding to files.
* Removed a (minor) memory corruption bug in the code for int 0x21,
ah = 0x09.
1999 Apr 6 - Build 2007
-------- ror4 (ror4@cryogen.com)
* Functions ax = 0x5700 and 0x5701 (get/set file date and time) now
return the right values at the right times. (They used to return
success when there's an error, and return error when there's a
success.)
* Removed the `/k' switch to the linker in `sys/sys.mak'.
1999 Apr 4 - Build 2006
-------- John Price (linux-guru@gcfl.net)
* added "version=" directive so that you can change the version that
the kernel reports. Usage: version=<major>.<minor> (i.e.
version=6.22)
1999 Apr 4 - Build 2006
-------- ror4 (ror4@usa.net)
* Fixed the file name parsing function (`ParseDosNames') so that it
handles single-character path names correctly.
* Also modified the functions which call `ParseDosNames' to check its
return value instead of assuming that it is always successful.
(This is not currentl useful, but it will be when error checking is
introduced into `ParseDosNames'. In other words, there'll be more
changes to `ParseDosNames' in the near future...)
* After wondering for a long time why the kernel text segment was
always getting corrupted when I ran DJGPP `bash' 1.14.7, I finally
decided to examine the code occurring before the handler for int
0x21, ah = 0x60, and I found out why... :)
* Fixed the problem of int 0x21, ax = 0x5d06 causing memory
corruption.
* Corrected the types of `internal_data', `swap_always' and
`swap_indos' in `kernel/globals.h'.
* Improved checking for invalid file names in `ParseDosName'
(although I'm still not sure whether the check is water-tight or
not).
* Changed the default path setting from `PATH=' to `PATH=.'.
* Output from character I/O functions now goes to standard output as
it should, instead of the console. Also, there's now a clear
distinction between console input/output and standard input/output.
* Tabs are now expanded during writes to the console device.
* Removed a hard-wired limit on the number of entries in a JFT.
(Although I'm not sure whether this is really correct...)
* Many other changes to the file descriptor handling code.
1999 Mar 29 - Build 2006
-------- John Price (linux-guru@gcfl.net)
* Changed boot loader so it prints some feedback info while booting.
Removed code to handle FAT12 and FAT16, and code to calculate the
start of the fat, rootdir, and data. Moved these functions into
the sys command. Now there are two versions of the boot loader
created, one to handle FAT16, and one for FAT12. These are
hard-coded into the sys command, so the need for the boot.bin file
is obsolete.
* created a new program (bin2c) to convert the boot loader binary
file into a header file that can be included in the sys program as
an array of bytes.
1999 Mar 29 - Build 2006
-------- ror4 (ror4@usa.net)
* Changed the class of `_BSSEND' from "STACK" to "BSS" in the
`drivers/' branch (which I forgot about in my last patch).
* Removed all traces of the `CONST' segment, since it was causing
`IGROUP' to be assimilated into `DGROUP', which shouldn't happen.
* Added a `(void)' cast to the `setvec' macro in `kernel/globals.h'
(`setvec' no longer returns the original ISR vector).
* Changed an incorrect error message in `sys/sys.c'.
* Removed `drivers/setvec.asm', since it's no longer needed.
* Also removed `kernel/krnstart'.
* The name field in a process's MCB is now filled in the same manner
as in MSDOS -- instead of being padded to the right with spaces, it
is now terminated with '\0'. Also, if the original file name
doesn't have an extension, the code will stop copying the file name
at '\0' instead of continuing to look for a '.'.
* Fixed the problem of the `switchar' syscall (int 0x21, ax = 0x3700) not
returning the correct value.
1999 Mar 28 - Build 2005
-------- ror4 (ror4@usa.net)
* Removed the need for `ipl.sys'. (!) The kernel makefile now
statically relocates `kernel.exe' to 0x60:0 and outputs the
resulting binary to `kernel.sys', and the boot sector has also been
modified to load `kernel.sys' at 0x60:0 instead of `ipl.sys' at
0x2000:0. (I chose 0x60:0 because it's the first 512-byte boundary
occurring after the BIOS data area, 0x40:0.) Finally, `sys.com' has
also been updated.
* Also changed the boot sector code in some other ways. In
particular, because `kernel.sys' is rather large, I had to add some
code to move the boot sector away from 0:0x7c00 to somewhere
higher. (For 640K systems the boot sector will be shifted to
0x6000:0x7c00. However, there may be problems on systems with very
little conventional memory -- I'll probably look into this later.)
* Made some minor changes to the assembler source files so that they
can compile on `masm'. (JP: The code still compiles fine with tasm
too).
* Also changed several incorrect label references in the assembler
sources. (JP: These changes fixed the "Fixup" errors we been
talking about in the list)
* Eliminated redundant re-makes of files in the various makefiles.
For one thing, `*.cfg' files are no longer generated from the
makefiles, but are independent from them. (I didn't like the idea
of having to compile an entire branch each time I edit a
makefile...) Also, intermediate files are now retained instead of
deleted.
* Also made some changes to `build.bat' (you'll know them when you
see them).
* Added a file `lib/libm.mak'
* Added a file `kernel/krnstart
* The code required to initialize the kernel (or rather most of it)
is no longer retained in memory after the initialization process is
done. I accomplished this by moving most of the initialization code
from `_TEXT' to a new segment named `INIT_TEXT'. Of course, I also
had to introduce lots of other changes in order for everything to
compile and run properly:
- Added code to `kernel/src/kernel/kernel.asm' to move the contents
of `INIT_TEXT' to the top of conventional memory and continue
from there. Control is only transferred back to `_TEXT' when the
kernel calls `p_0'.
- Many functions are called from both `_TEXT' and `INIT_TEXT'. To
fix this, I created far wrappers for these functions which can
then be called from `INIT_TEXT'. (E.g. for `execrh' there's a
corresponding far function named `init_call_execrh' which simply
calls `execrh' with its own parameters.) One exception to this is
`printf' -- instead of creating a far wrapper for a near
`printf', I created a near wrapper for a far `printf' (now called
`init_call_printf'), because it was easier that way. :)
- Most functions which are required only during initialization time
were shifted into `INIT_TEXT'. (There are still some functions
which should rightfully go into `INIT_TEXT', but are retained in
`_TEXT' as far functions, because I found it too difficult to
move them out. :( ) Because Turbo C only allows at most one code
segment to be defined for each module, I had to shift some
functions around within the source tree -- the file
`kernel/src/kernel/proto.h' says it all.
- A cosmetic change mentioned here for completeness: all functions
defined in `INIT_TEXT' are now marked with the word `INIT' (in
fact a null macro) so that the reader can easily distinguish them
from functions defined in `_TEXT'.
* Replaced `exit' calls with `for (;;);'.
* Changed `strcpy' into a macro which calls `scopy'.
* Also redefined `setvec' to be a macro (I didn't want to waste time
writing a far wrapper for it).
* Removed the `break_key' function in `kernel/src/kernel/kernel.asm'.
* `low_int25_handler' and `low_int26_handler' are now of type
`void interrupt far()' instead of `void near()'. (I hope I updated
`entry.asm' correctly -- I never tested `int 0x25' and `int 0x26'...)
* Changed the class of `_BSSEND' from "STACK" to "BSS" -- "STACK" is
now used for a separate stack segment (`_STACK').
* Assembler modules now include `segs.inc' instead of having their
own long list of segment definitions. (Some day I'll update the
makefile dependencies to reflect this.)
* Also made a few minor changes to the assembler modules so that
`masm' won't complain.
* Changed the `-X' switch in `kernel.cfg' to `-X-', so that I don't
have to worry about C module dependencies.
* Removed the definition of `CFLAGS' from the makefile -- everything
is now in `kernel.cfg'.
* Created a file `kernel/src/kernel/init-mod.h' which is included by
modules whose code is supposed to go into `INIT_TEXT' instead of
`TEXT'.
* This diff solves the problem of the MCB of a process not having a
correct value in its name field (bug report #6).
(The definition of the `toupper' macro is because I shifted the
`toupper' function into `INIT_TEXT' a while ago, and therefore
can't be called from `_TEXT' now...)
-------- John Price (linux-guru@gcfl.net)
* Made changes so you can create a directory with the same name as a
volume label, but you still can't rename or delete it!
* Fix findfirst and findnext functions so that act as they should.
(i.e. If the attrib has only the volume label set, then it returns
the volume label entry in the root directory, else it returns the
files/directories that are specified with the attrib, ignoring the
read-only and archive bits (these are always returned).
* reorginize the source tree. Removed IPL directory, and command.
Moved all the file system C files into the kernel directory.
Modifed build.bat, clean.bat, and all the make files to reflect the
new tree.
* changed so that kernel will look for a "fdconfig.sys" file, and use
it INSTEAD of config.sys. If it does not find it, it will look
for, and read config.sys, if it exists.
* Fixed so that if you call an INT 21 function with AH containing a
unsupported function, the carry flag is set.
