My old BFG 6800GTOC AGP supported CGA in old dos applications at the command line. I have a few small, old, but critical aps that I need from time to time that use these graphics modes.
My new EVGA 7950GTKO gives me this error:
---------------------------

Command Prompt - portalinv
The NTVDM CPU has encountered an illegal instruction.

I'm wondering - did the nVidia PCI-E line stop supporting DOS/CGA? I read elsewhere of a person with a 7800 who can get basic graphics in DOS - but I'm not sure if he's PCI-E or AGP.
Before you bring up DOSBOX, sadly neither of these programs will run under DOSBOX emulator software, so that's not an option in this case. (Although at least I can play Magic Carpet with that. 😎 )
Any and all DOS based graphics mode generate this blank screen of death and error. I actually went into my old copy of Qbasic and activated each mode, one at a time.
