This same board works in an Sun Ultra 5 under Solaris and also works on
slower PCs using Linux Red Hat 8.0 and 9.0. (i.e., all my stress testing
was done on a MoBo with an Intel 815E Chipset using an ICH2 I/O Controller
Hub. It worked beautifully there!)

The last item "Communication controller" is our card. lspci -vv for our
system follows (ours is the last one):
