The FAQ does indeed answer this question; section 10 specifically covers 
graphics programming under DJGPP.  It also gives pointers to several 
locations where you can find more information.  Also, you need to get the 
latest version of the FAQ (faq201b.zip), because it has updated info on a 
lot of things.

To summarize the FAQ briefly, there are two main ways to put a pixel to 
the graphics screen:  use the _farpokeX functions to write to the 
specific memory location you want, or enable near pointers and write 
directly to the graphics area.
