I have a 3com 3c905b-TX card in my system and I need to get it working , but
I have been running into a peculiar problem.  After my initial network file
configuration and reboot. ifconfig out putted that the media type on my card
was "none". looking at this and then at the hub noticing there was no link
light I then tied to get the right media into ifconfig. So I tried the
following:
ifconfig ex0 192.168.0.1 netmask 255.255.255.0 media 10baseT up
ifconfig ex0 192.168.0.1 netmask 255.255.255.0 media UTP up

and both exclaimed the:

 SCIOIFMEDIA Device not configured

I am running NetBSD-1.4.1 (i386)
