hi ya

if oyu have onboard nic...and no others.... it's eth0

if you plug in one pci-based becomes eth0 by
default... and onboared nic becomes eth1

if you plug in two pci-based nics...
the one furthest from the atx connectors is eth0
and eth1 is the other pci nic...
and onboard nic is eth2

you can remapp which is eth0 and eth3....but why go thru
that headache ??

-- there might have been a solution posted in the eepro mailing list
   to remap eth3(onboard nic)  to be eth0....

have fun
