Both of these NICs are definitely on the motherboard and since both are
working fine with all the boards I'm having I suspect that something
is wrong with that particular board that Kirk got.

The Tyan web site(http://www.tyan.com/products/html/thunderk7.html)
actually says that the on board NICs are 3c920 (that's also what the
Thunder K7 user's manual says), however a search on the 3com site doesn't
turn up anything about 3c920.
