Assuming you mean the 32-bit system, Ive recently installed FC5 on one of these on an Intel 975XBX mobo with only one very odd problem. I wanted to run this system in headless mode (i.e. no VGA adapter). The mobo manual says this is possible, so I configd it to use the serial port as console. In this mode, the kernel only ses one cpu. With the VGA adapter plugged in (but still using serial console) 2 cpus are available and everything so far works as expected. This is intended to be a node in a compute farm so it doesnt exercise many applications... Cheers, Terry.
