dos: int 25/26 may be register-dirty; wrap them in assembly

2009-11-13T21:44:08+00:00

int 25h and int 26h are known to be register-dirty for some versions
of DOS -- unlike int 21h, which is usually clean.  As such, wrap those
in assembly functions.

dos: don't add the linker script twice on the ld command line

2009-11-12T00:29:53+00:00

My version of the linker can deal with it, but others might not be so
smart.

dos: always try the FAT32-aware direct I/O calls first

2009-11-12T00:05:34+00:00

Always try the FAT32-aware direct I/O calls before trying the legacy
raw I/O calls.  The reason for doing this is that the FAT32 stuff may
be implemented as an add-on.

dos: DOS version 7.10 is 0x070a, not 0x0710...

2009-11-11T23:52:37+00:00

Fix DOS version 7.10 (first FAT32-capable version) check.

Perhaps we should just call the FAT32 calls blindly and fall back to
the old calls if they fail?

dos: try to handle both raw DOS mode and Windows mode

2009-11-11T07:46:03+00:00

The locking API works very different in raw DOS mode and in Windows
mode.  The hierarchial locking is only available in the latter mode;
in the former mode we can only use levels 0 and 4.

dos: make DOS installer work under WinME

2009-11-11T06:10:23+00:00

At least under WinME, the DOS installer did not work as advertised.
With these modifications, it seems to work okay.

dos: add pointer to PE header in binary

2009-07-10T23:40:20+00:00

Explicitly add the pointer to the PE header in the binary.  That way
we might be eventually able to create a merged DOS/Win32 binary.
