Hi

from the boot messages, i can see that the network
devices are started up properly. Strangely enough,
the one that doesnt seem to be assigned an IRQ# is not
having any problems, but one of the ones that is.

Here are the boot messages

de0: <Digital 21140A Fast Ethernet> port 0x4000-0x407f

Here goes my ifconfig
