Log:
[NTVDM]
Mouse:
- Remove now useless code in mouse support in BIOS.
- Implement INT 33h, AH=1Bh "Return mouse sensitivity" (returning hardcoded
standard values since we don't support custom sensitivities) (AH=13h and 1Ah are
marked as UNSUPPORTED).
- INT 33h, AH=1Fh "Disable mouse driver" returns in ES:BX the old INT 33h vector
value: implement that.
- Implement INT 33h, AH=21h "Software reset", AH=24h and 4Dh and 6Dh
"Software version and mouse info", "pointer to copyright string" and
"version 'string'" functionalities.
DOS:
- Initialize in Win2k3-ntvdm-compatible order the DOS drivers: NUL, then CON, then XMS,
and then EMS.
- Fix segment/offset inversion usage in INT 21h, AH=5Ch "Lock/Unlock region of
file": when using MAKELONG macro to build a far pointer, the first parameter (loword)
is the offset, and the second parameter (hiword) is the segment.
