DJGPP uses a protected mode scheme that rearanges your adressing system;
"char *video_buffer = (char)0xa00000;" might work. Check out the _DJGPP
Game Programming Page_ by Mr. Brennen Underwood for an excellent
explenation of how this works, a tutorial on "How to access the VGA in
DJGPP", and comparisons of DPMI vs. real mode programming. The site also
sports a nuber of links to some very useable works, with perhaps an
execption to a little cd player(hehe), but I suppose even that did contain
some quite good code.
