Adding a 2nd NIC (again)

[Michael Boyd <Michael.Boyd@maunsell.co.uk>]

I managed to lay my hands on a 2nd 3Com 3c509b NIC at the end of last
week and put it in my old 486 firewall.  When the machine boots it knows
that eth0 and eth1 are NICs.  My question is, how do I assign an IP
address to the 2nd card?  I modified the 'interfaces' file last night
but that didn't seem to do it so I changed it back.

Thanks

Mike
