2nd 3com nic

[kct@elgin]

I've got an onboard 3com nic and am trying to add a 3c905c - txm card. Both work, but not at the same time. When I plug in pci card, the onboard network card disappears. The irqs are being assigned separately, both cards show up in bios information, but they are trying to use the same base io address, 0x300. I can't find anything on 3com.com about moving one to a different address and there aren't jumpers to change. There is nothing in the bios setup for moving the onboard nic to different address. How is this handled in Linux? (RedHat 7.3)

See if adding

alias eth0 <module>
alias eth1 <module>

to /etc/modules.conf helps.

Being PCI devices, the resources should automatically be assigned by the system and os so they don't conflict with each other.
