 2. Using Mesa for DJGPP
 
+   Q) Every test I tried crashes badly.
+   A) If you have compiled with SSE and you're running under plain DOS, you
+      have to disable SSE at run-time. See environment variables below.

    A) Is that a question? If you have a 3dfx Voodoo (any model), you're
       lucky (check http://sourceforge.net/projects/glide for the DJGPP port).
