One word of caution, don't be too disappointed if a modern NIC doesn't
work in that very old mobo.  My first x86 computer, a PPRO-150 on in
an Intel VS440FX mobo doesn't recognize a Linksys EG-1032 (a $25
Gigabit NIC pci card).  All the later mobo's I have work just fine
with that card.  I never bothered to figure out what the exact problem
was, but I do notice the PCI spec was revised several times along the
way.
