Subject3Com 556B Tornado not working
From
I have a HP Omnibook 500 with a 3Com 556B miniPCI ethernet/modem combo. Try
as I might, I can't seem to get the card to connect to the network. My
question is, how do I figure out what is the problem here? At this point, I
do not know if the card or the kernel is at fault. Please CC me as I am not
subscribed to the list.

Thanks for your help,
Rahul

P.S. This is on RedHat 7.2 with kernel 2.4.9-31. Please let me know if I
should upgrade to the stock kernel.

Here is the output from "modprobe 3c59x debug=7":

whole-frame receives.
