Try the following from the console (logged in as root)
suppose eth0 is your internal LAN, otherwise use eth1 and EthernetDriver2
modprobe e100
ifconfig eth0 192.168.1.1
If the server works with the above settings, enter the commands below
/sbin/e-smith/db configuration set EthernetDriver1 e100
/sbin/e-smith/signal-event console-save
Hope this helps
