Second NIC not detected!? They are same cards but the other is not seen, it fails during boot up.
Why would that be?
I connected my win box to it and the lights are on, I use crossover cable.
Thanks for any help.

during boot up:
tulip eth1 does not seem to be present?
It recognizes one but not the other one!
Thanks.

Sorry do you have two cards with 1 port each or 1 card with 2 ports? if it's two different cards, one might not be seated correctly within it's expansion slot? or even possibly be broken...

I got two NIC cards and it does seat properly, see the output of ifconfig -a:

I searched the Internet and it seems like it needs some kind of e1000 or 2200 driver file, I have to figure that one out yet.
Thanks.

It seems you've got ISA cards... They are using interrupts 3 and 10. Maybe there's IRQ conflict for one of them. Try to use cat and have a look at dmesg output . If these are PCI cards (they should share the same IRQ), but in that case try

They are linksys cards:
02:09.0 Ethernet controller: ADMtek NC100 Network Everywhere Fast Ethernet 10/100 (rev 11)

02:0c.0 Ethernet controller: ADMtek NC100 Network Everywhere Fast Ethernet 10/100 (rev 11)

It worked OK last night but now it does not work again!?
I get this if I try to activate it:
"tulip device eth1 does not seem to be present, delaying initialization."

Thanks.

Can you exchange the cards?

You know, just to check a hardware failure.

I did swap them and that night it worked for about the moment I had the system on. After it failed every time.
I know one of them sets up automatically while the other I need to set up so my other machine can access it. I followd the examples but without having it being recognized it was no use. I would buy 3com but those cards are $100 a pop. How do I know it will work!?
I also put in Intel card but that was not recognized either. It might be the motherboard how it shares its PCI interfaces or something like that.
Thanks.

Maybe your BIOS need be reconfigured... Load the default values on the BIOS.

Another thing you can do is test the cards one at time in differents slots.

But, if your BIOS has not change before the problem... I think is a card failure. The link ligths sometimes do not indicate a good card (I have seen this situation before).

If you can, try your cards in other machine.
