This is a pretty old machine, it will take a bit of sleuthing to see if I
can find an updated bios. When this box was new (1998?) I used this as an
NT 4.0 box, I know I kept the bios up to date then. I did find the bios
had plugNplay aware OS on, I switched it to off. It might be acting a
little better in terms of throughput via speed-testing.

I did not see any difference in the relative dmesg's.

I still get some I/Oerrors:
clarity 20 # netstat -i

Something else I noticed with ifconfig:
wm0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

Apparently I have some hardware capabilities on these cards I do not have
on. Would turning these on help? If so, how would I do that?

Much thanks,
