The PR440FX is NOT a server board.  It was designed by the desktop group
as a "workstation" like board.  This is why it has a built-in NIC, Sound,
and SCSI.  It is missing serveral of the features I would consider 
necessary to perform as a "high performance" server board (only 512MB of
mem, only 1 PCI bus, etc.)
