2 ethernet cards.

[Gertrude]

I have a pc with a built in ethernet card in it, and a Linksys pci ethernet card.. I installed the tulip drivers for the Linksys card, and it works fine... but it does not seem to detect the built in ethernet.. Im using debian.. I detected both with Slackware..

the mac addresses of eth0 and eth1 are the same?


FuR:/etc/network# cat interfaces

Ignoring unknown interface eth1=eth1.

What onboard ethernet do you have?

[rioguia]

what is the output from
dmesg | grep eth

lsmod | grep Ethernet

lspci (only need to report NIC related info)

I noticed that ifconfig reports eth0 and eth1 as both using IRQ 11. If that' correct, you need to clear that up:

1. Turn off Plug-N-Play support in your BIOS. It's the number 1 culprit when it comes to resource conflicts in Linux.

2. If that doesn't work, move the PCI card to another slot. That should force an IRQ reassignment.
