Disable that onboard video, it eats too much bandwidth making use of 
main memory and emc won't like that at all.  Put a cheap ati 9200 clone 
in it instead.  You'll think you just put a supercharger with 20 lbs of 
boost on that machine.  I tried it, with an xp-1400 athlon & half a gig 
of ram and it was one sick puppy until I put the video card in.
