I bought this board over a year ago to run amd64 (you're running i386). But in the end I trashed it for running amd64 since one of then involved developers also tried to use the board without much success. It was running fine with amd64, 1 CPU, 2Gb, but as soon as I added the 2nd CPU the slightest load crashed the system somewhere in IPI-areas. After long discussions I came to the point that it was easier to get a new motherboard, so I got a Tyan Tiger S275. Which as not yet failed on me. So if ever you'd like to run amd64 on this system, even now you've determined the problem to be the load on the memory-bus, be warned that odd things could be happening. --WjW
