Two tulip NICs in one box for ADSL ?

Background: I'm considering ADSL, and so I need two NICs in my gateway (I'll be using an ethernet DSL modem, makes more sense than USB).

Using IPCop 1.4, and the box is a Digital Celebris FX 5200.

This box has an on board NIC which I have been using happily with the LAN side of the setup (eth0), and I stuck an old DE205 card (it's an ISA).

At first it didn't get seen, and although IPCop was able to probe it and it appeared to get setup, I was unable to issue ifconfig eth1 as eth1 didn't exist.
I switched PnP OS off in the BIOS and again IPCop was able to probe it.
It gets assigned IRQ5 this time, and I am able to start the interface.

The problem is that while ifconfig shows it's got an interrupt (MAC addresses removed):

Code:

eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:01
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:110 errors:0 dropped:0 overruns:0 frame:0
          TX packets:82 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:11573 (11.3 Kb)  TX bytes:9311 (9.0 Kb)
          Interrupt:11 Base address:0xec00

eth1      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:02
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Interrupt:5 Base address:0x300

lspci shows it doesn't exist:

Code:

      I/O at 0xec00 [0xec7f].

What am I missing ?
Do I need to attach a DSL modem to get a true picture of any problems I get that are going to be local to my configuration ?
I don't have ADSL yet, as I want to sort out this stuff (if possible) before I sign up, assuming I can get it - I don't like the idea of paying for the access when I'm really stuck on dialup ;p

Well I just realised now that lspci won't show it as it's an ISA card

Should have noticed that earlier.
Is there anyway aside the ifconfig utility that will show the IRQ etc ?
or can I trust this alone ?

Code:

Oct 24 14:59:44 akashic kernel: eth1: DE205-AB at 0x300, h/w address xx:xx:xx:xx:xx:02
Oct 24 14:59:44 akashic kernel:       has a 2k RAM window at 0xd0000 and requires IRQ5.

I'm guessing this is enough (this is the NIC probe from /var/log/messages), coupled with the use of modules.conf which I'm suspect IPCop takes care of.

So I'd say I've answered my own question.
