   I think that perhaps you do not need to declare far pointers
   in DJGPP.
unsigned char *ScreenMem = (unsigned char*)0xa0000000L;
   After setting your video mode, just access screen memory
   directly.
#define Putpixel(a, b) ((*(ScreenMem + a) = b))
   This should work for mode 13h. Other modes are more difficult
   to work with, naturally.
