[net.micro.pc] Accessing EGA memory

kreek@rocky2.UUCP (Mary Jeanne Kreek) (05/07/86)

Does anyone know how to make direct access to the graphics memory on
the IBM Enhanced Graphics Adapter? I have tried with char pointers and
bitfield pointers in Microsoft C, but I can only get white dots on the
screen. What I would like to do eventually is to set up a nybble array
D[640][350] (or a char array if that could be done with the second
graphics page) in the graphics memory.
