...and, fwiw, they also have a mini-pci version that is geared for
their net4501, etc. single-board computers. Since these things have
AMD SC520 or NS Geode CPUs on them, the offload card is faster than the
CPU :-)
(Though, you have to beware -- if you're using all 3 10/100 ports on
the net4501, there is very little PCI bus bandwidth left over for the
Hifn, so design your system accordingly.)
