The network card is trying to use irq3, which is normally reserved for
COM2. I''m wandering whether this is causing problems.

Can you try configuring the card for a different interrupt line?

The bios on this board doesn''t give any direct control over interrupt
lines. However, by playing about with some of the configuration options,
I was able to shift it over to irq5, and then irq10. Both failed in
exactly the same manner.
