    Ask yourself this one little question:

    If a video card could read from DOS memory (ie.. over the bus) fast
    enough to send to a monitor, then why is there such a thing as
    display memory?????? We could use extended memory to act as a frame
    buffer.

    You guys should buy a book entitled "Programmer's Guide to the EGA
    and VGA Cards", 2nd Edition by Richard Ferraro.
