Alright people,
YES YOU CAN ACCESS VIDEO MEMORY DIRECTLY UNDER OS/2
If you don't believe me, get vgalib.zip from the hobbes
pub/uploads directory.
I have given source to write DIRECTLY to the video ram in
320x200x256 mode.
All that needs to be done to use this in text mode is to change
the address of the physical video buffer start, and length
and change the parameters that go to VioSetMode().
If you have any questions on it, send me mail, I have some
docs for these Vio calls...
Later,
John Stone
