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.
