3C905TX not connecting.

I have usually used SMC cards in the past but recently I decided to use a
3C card in a new box I'm setting up mainly because of its popularity.

I don't seem to be able to get it to work though. Relevant bootup messages
are the following:

I also get a "eth0: unknown device"  (or not found) error followed by
"Network unreachable."

Any ideas please?
Thanks.
