NIC and LAN setup

[Paul E Condon <pecondon@quiknet.com>]

I am Debian newbie. I have a LAN that was running and is now in need of
reconstruction. On the LAN were two Linux boxes and two Macs. The Linux
box that provided internet access via ppp has a Netgear fa311 NIC. This
card is not supported by potato. I have obtained another NIC, a Linksys
LNE100TX, which uses a DEC tulip chip and should be useable with potato.
I would like to do just what is needed to configure the potato machine
for this card and for LAN networking. I would like to avoid simply
running through the complete install process for just this one change
(and the consequent configuring of a network interface). How can I do
this?
