Does the output of dmesg show an eth0 device being detected? If not,
you may not have the write drivers in there. BTW, I highly recommend
using the standard pre-built 2.4.18 kernels unless you simply
can't. Saves a lot of recompiling ;-)

If you do have an eth0 device, what is the output of '/sbin/ifconfig
eth0'?

If that is sane, what does 'ifup eth0' do? If you get an error, what
is it. Sometimes you have to do 'ifdown eth0' followed by 'ifup eth0'.

Basically, what I am getting at is "how do you know your network card
is down?"
