This is rather premature, sorry. I'm sure theres a way, but when I;
char *vidmem=(char *)0xA0000000L;
And then try to plot a pixel or somthing;
vidmem[y<<8+y<<6+x]=color;
DJGPP returns a general protection fault.
I can't figure out how to use an inline assembly block either, I
can do interrupt calls, but bios is waaaay too slow.
Any information would be much abliged, I will search the
doc's, but I am so excited about programming in DOS for
both platforms.
Love as always,
Jonathan Nix
