I've never really understood how to get beneath the BIOS to program
the EGA board in 640x350 APA color mode. I never had any trouble
when it was hooked up to a monochrome monitor in 640x350 APA mono
mode--I just wrote to the display addresses and everything worked.
This approach seems to fail when using an enhanced color display.
Can anyone tell me the sequence of operations I must perform if I
want to write a bitmap in color APA mode (though you can assume, for
simplicity's sake that I'm only interested in 'monochrome' emulation.)
I have the Options and Adapters manual as well as the Seminar Proceedings,
but both are pretty obtuse.
Thanks,
