      INT10MDA video BIOS patch TSR for MDA video card   11/00

Recent AMI BIOSes simply don't support the old MDA (TTL Monochrome) card...
even though they are used on motherboards with ISA slots.  This TSR program
adds the missing Int 10h functions for DOS programs.

Can be run in AUTOEXEC or your ACAD.BAT file after Mode Mono, which initializes
the MDA card.

Obviously this will not be overwhelmingly popular, but there ARE a few
people still using MDA cards for debugging and for DOS CAD programs, and we
use the old Mono monitor as a 'clipboard' when writing programs with the
POST-7ZX program included.
Surprisingly enough, you can use the Mono card in Win 9x too, where we use
it as a second 'clipboard' for programs running in a DOS window.

With our new AMI BIOS motherboard, if a program sets Mode 7 (mono) it switches
to mode 0Eh, so be sure to send AMI lots of nasty emails.
Gigabyte simply NEVER responds to email, so you can bet that niether Gigabyte
nor AMI will see any more of our money.


Test setup:
Gigabyte GA-7ZX Socket A motherboard, with Duron 600.
Video cards - Trident 9880 Blade 3D AGP and an old Mono card
Release 10/386 with the Trident RCPTVGA driver, patched for the 9880
DOS 7.10 (Win 95B)

It's not perfect, but it lets you run R10 which is perfectly adequate for
2D drawing and SO pleasant now that machines are finally fast enough.
It saved us from having to go back to single-screen and rewriting our menu
(which had been customized to use all lines with no Command Scrolling area).

All programs include .ASM source.  Read the .ASM files for more info.
These are included:
  the patched Trident video driver
  QC2, a crude text editor for AutoCAD R10
  my ACAD.BAT file
  BLDP600I to initialize the Mono card in your AUTOEXEC.BAT
    MODE MONO will do the same thing but leave you on the Mono screen.
    It also installs a cute beep sound if your CPU is around 600 MHz.
  POST-7ZX to post the current text screen screen on your other monitor
  SWMO-7ZX to switch screens
