For obscure reasons, I need to run GRAPHICS.COM under DOS 3.3 (to get
VGA screen dumps). Unfortunately it gives me the message:
Incorrect DOS Version
when I run it under DOS 3.3. I just tried tracing through the binary,
made one obvious change, one less obvious change, but it still would't
work.
Any patches out there?

The version-check code in most of the DOS 4 external programs looks like this: B4 30 MOV AH,30 CD 91 INT 21 3D 04 00 CMP AX,4 75 03 JNZ 176B If you replace the last line of code (75 03) with NOP's the version test will be ignored. -- l\ /l' _ Mike Schuster ...!dasys1!schuster l \/ lll/(_ Big Electric Cat schuster@dasys1.UUCP CIS:70346,1745 l lll\(_ New York, NY USA BIX,DELPHI,GEnie:MSCHUSTER

Does anyone out there have a program that will convert binary numbers to decimal numbers? I need one that will work in DOS. If you have it, please send it. Thanks. Rick Hung
