Hello, I'm looking for some technical help and FR never steers me wrong! I have an older Hewlett Packard xw8400 workstation that came with one CPU and it is now running 64 bit Windows 7 with the 2010 BIOS update. I've now inherited another 8400 that isn't working and I've transplanted the RAM, a hard drive, and the CPU to my original machine. The motherboard has two CPU slots and the new CPU fan runs fine in the slot. But I'm not getting the new CPU to run. I also can't find in the BIOS how to enable multiprocessor support....
