Emulation of DOS full screen mode on a non-VESA graphics card?

    I recently bought a new NVIDIA 7600GT graphics card, and unfortunately
    found out only later (it's not mentioned on the product page) that this
    card does *not* support VESA standard VGA modes. So when I try to switch
    into DOS graphics fullscreen mode (with any application) on Windows XP
    Pro, it gives me an error message "16 bit MS-DOS subsystem: The NTVDM
    CPU has encontered an illegal instruction...."

    As I read here that Virtual PC emulates its own legacy video card, would
    that solve the problem and allow to run DOS full screen applications via
    Virtual PC? (Or does anyone know another solution for this problem,
    except for buying another graphics card?)

    Thanks and best regards,

  2. You might also want to search for the emulator DosBox. I find it is better
    for running DOS programs.

    Hi Bill,

    thanks, that was a very good tip! I tried it, and indeed DOS fullscreen
    seems to work so far without problems even on my non-VESA graphics card!

    Best regards,
