4ffc5c10a5 fix bug#121 don't look for 123? unless still looking for verb at start of line 
allows correctly parsing lines like SHELL=4DOS.COM which otherwise strips 4 leading to looking for shell of "DOS.COM"

3d1ba0d486 config: build master environment during FDCONFIG.SYS processing 
lDebug wants to access the environment while executing
as a device driver. Instead of building it in a variable
then copying it to 68h:0 after FDCONFIG.SYS processing,
just build it there to begin with.

8e6fc98a94 config: bugfix, make struct array configcommands static (fixes #73) 
A crash was introduced by the prior commit, ee255d2. I
tested that the kernel still did build with gcc, but I
failed to test whether it also still runs. Turns out that
apparently changing the pointers to static made it so gcc
put the structure into the init data segment and
implicitly called memcpy to put it on the stack. That's
wrong, however. We depend on #define to convert all calls
in init to the init text copies of memcpy etc. The
implicit call by gcc however attempts to call the HMA text
copy of memcpy which happens to be at another offset.

The fix is to make the entire array of structs static so
that memory for it is allocated only in the init data
segment, not on the stack. This seems to work for both
gcc and OpenWatcom (no warnings, it builds, it runs).

b562983222 config: add the CONFIG, ALTCONFIG, and OLDCONFIG kernel command line commands 
CONFIG takes precedence and is by default initialised
to the empty string, that is, skipped. ALTCONFIG is
used to specify the 'alternative' filename and defaults
to fdconfig.sys. Finally, OLDCONFIG defaults to the
config.sys filename.

89d97b18de Fix ASMCFUNC (FAR) functions for ia16-elf-gcc. 
We need to use make the functions vararg (,...) to make them cdecl.
For FAR functions we need wrappers.

4b08676a48 when updating MCB to add UMB chain, redetermine top of memory again in case changed (e.g. device driver relocated EBDA) to avoid corrupt MCB chain. Revert checking for switches only on pass==0, causes error due to portion of command line not skipped when reevaluated on next pass. Allow undocumented -1 for /E: switches option for use calculated EBDA size when moving. 2013-07-17 22:58:44 -04:00
