you reboot while files are open... Reported by Hardi Stengelin :-).
Always test *link_fat* result. New function is_free_cluster. Extra
checks in *link_fat* (bad r/w offset, i/o, write) and *next_cluster*
(dangling chain: bad value in chain) with short messages (no msg for
bad chain start). Shorter "Bad DPB" (FAT size) msg. More comments!
Update FS INFO on disk only when needed. Check if chain EOF was at
expected place when extending. Call *link_fat* before! *setdstart*
when a FAT chain grows. [Q: Does 0 byte write always trunc? Why?]

the virtual / created-by-subst drive when it resolves relative
paths, even though truename returns the "real" drive and dir
of where your files actually are in the end. Using the current
directory of the "real" drive made truename give wrong results.
PS: If "subst e: d:\" says "physical path x:\ cannot be made",
then it refers to "making" a root dir. "subst e: d:\foo" works.

MODULO 1 MB (paras = low_16_bits(pages<<5) ...) because for e.g.
Turbo C++ 3.0 needs this: Their IDE is 1.3 MB BOSS NE style EXE,
the first < 0.3 MB load a DOS ext which loads and runs the rest.

Removed HaltCpuWhileIdle handling from GetBiosKey because it is
only used *before* IDLEHALT is processed anyway - in the config
sys menu *and* in CheckContinueBootFromHarddisk. Adding s.th.
like "switches /i" would be a way to enable it a bit earlier.

if no directory given in template if DOS version is 5.
Older and newer DOS versions just use no dirspec in that case.
This helps ftp.sac.sk/pub/sac/pack/iup067.zip exepacker which
tries to rename the temp file to a file in current directory.
Prepared Truename (21.60) to return 0 if okay, 3a00 if char dev
(and not JOIN / network?). May need further coding to actually
have the intended effect...? Note: The shell TRUENAME command
may change names for display!
Changed the "true DOS version" for FAT16 kernels from 5.0 to
6.22 to reflect the updates in 21.5a and 21.60, other 5 / 6
differences are not simply in the kernel but more in COUNTRY,
KEYB, HIMEM, SMARTDRV, DBLSPACE, EMM386, COMMAND and so on.
In addition, 6.22 is a popular version number to report :-).

again, as this made the kernel crash in Bochs in PostConfig
(or short before or after it). FASTBOOT should still be okay.

"HLT on idle" (dosidle.asm, int2f.asm) and KEYBUF=n[,m] to relocate
the keyboard buffer to another area in the 40:ac..40:1ff range. Global

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.

the old "version 1.1.35 (Build 2035b-cvs) [Jul 23 2005 12:34:56]"
