[ILUG] 2x Network Cards

[nick_elliott at ie.ibm.com]

I have set up a few machines running two IBM token ring cards and never had
any problems.
Just set up the network details and hey-presto, it works.
One thing to check is that in the /etc/conf.modules make sure you have an
alias to the proper device driver for your cards.

I have set up servers no problem in the past with 2 network cards using
redhat Linux, but I was using either Intel cards or 3coms. However I seem
to
remember something about some cards, where if you had more than one of them
you had to specify the MAC address for each card somewhere, I can't for the
life of me remember where, but I hope this helps point you in the right
direction.

Hi2all,

we're setting up a machine in here as a gateway.  What seems to be the
first

hurdle is to actually get the machine going with two network cards.

The machine is an old P166; 32MB RAM; ~1.5GB HD (made by ultra I believe).

The cards are two Maplin specials:

     UNEX 10Mbps PCI BNC & RJ45

and to be honest that's about all info you get in the package.

Now, I've been reading Ethernet/Firewall howtos.  Apparently given they
are PCI it should just detect them both.  I looked further into the ISA
stuff about I/O addresses and IRQs.

I'm a little bit puzzled.  Apparently on the old PCIs the you set IRQ and
I/O addr.  Fair enough.  These all must be unique on the system. Sound.

But, with an PnP ISA or PCI you don't have these settings.  So presumably
PnP is setting these (if this is the definition of PnP I apologise) and
the card is happy with that.

Now we have two identical PCI cards.  I assume PnP will know to set them
to differing IRQ & I/O.

Linux is complaining that the eth1 device is not found. But eth0 is
fine.  Are the above assumptions correct re PnP etc?  So can anyone figure
out what's going on??  Sorry my knowledge of hardware is patchy at
best.

Thanks

Gavin
