First, I have to mention that I hate rtl8139 cards :-) However, if it works for you ... Anyway, I'm guessing these are PCI cards, yes? If so, you don't need to worry about IRQs. As someone pointed out recently[1], PCI NICs are detected in PCI order (the order listed by lspci; the physical order in the machine generally). This means that your present eth0 could become eth1; write down the MAC of your existing interface before you insert the new one. You don't need a new driver or kernel since you've already got the rtl8139 driver. Once you start your computer, run dmesg | grep '^eth' You'll see something like this (I have Netgear FA-311s in this box): eth0: NatSemi DP8381[56] at 0xc4825000, 00:02:e3:02:c7:45, IRQ 11. eth1: NatSemi DP8381[56] at 0xc4827000, 00:02:e3:02:dc:be, IRQ 10. eth2: NatSemi DP8381[56] at 0xc4829000, 00:02:e3:02:dc:ca, IRQ 9. Look for the MAC address of your old eth0 to see which interface that card is now assigned. To assign an IP address to the card, edit /etc/networking/interfaces and add a stanza for eth1. Further details available in interfaces(5) (or on this list of course). Then just run ifup eth1 I have no idea what /etc/ifstate is, but I'm pretty sure you don't need to edit it. -- Nathan Norman - Incanus Networking mailto:[EMAIL PROTECTED] A young man wrote to Mozart and said: Q: "Herr Mozart, I am thinking of writing symphonies.
