Yeah, I thought that might be the answer, find the read or fread
routine, and re-write it to include the new linear frame buffer
selector.  Although, thinking about it, since DJGPP is PM, and lets you
play with megs of memory, it's probably just faster to have two
routines.  One, to store the bmp image into memory, then, one to display
the image from the buffer.  Anyway, thanks for the help.
