OK, I have it at least partially working. For some reason it was
unhappy (VERY) with my .xinitrc file left over from the old days. Go
figure?!?!

I erased the .xinitrc file and just type startx and it work. Three
terminals on the screen. xclock. Everything looks normal.

I am still getting messages about the MTRR but it doesn't stop X from coming up.

I get back on this tomorrow and see if I can get fluxbox running.

Thanks,
