You might also look at the original mini-x source, or the new stuff,
and look at the files kernel/graph_ega.c, and kernel/ega.x. This shows what the
mini-x driver does on GC's that expect XOR draw modes. In the mini-x ega
driver, there's a single little procedure, ega_setmode, that sets up the hw.
I'm pretty certain that we've got to implement the XOR modes, or the
samples won't work. (including the cool new one, world)
What is ClanLib?
