I bred it myself. I have a recombinant DNA splicing chamber in my back
yard. It may have been contaminated, though... my cat loves to catch mice
and drop them in there.

I think the manual outright lies. I found an old 10Mbit ne2k card which
I'd forgotten about (too bad it's too late to return the second 8139 thanks
to a stupid return policy); a 10Mbit is all I need for the upllink) and I
put the 8139 in slot 1 (which is where the nonfunctioning eth1 was) and the
ne2k in slot 2 (where eth0 was), but then the 8139 still didn't get an
interrupt, but when I reversed them to put the 8139 in slot 2, it started
working again. This indicates to me that slot 1 isn't actually bus-master
capable (even though the manual clearly states that all 3 PCI slots are).
It was a cheap motherboard on clearance for $20, though, so I guess I can't
complain too much. Well, I can, but it'd be petty.

The nice thing about living in a small-ish desert city without a light or
smog pollution problem is that one can actually see the moon here. :)
