Hi there.
First, I believe that NW has the ability to receive an IP address via DHCP, as I've seen this during installs. However, I don't really know how to do this, nor do I have any inclination.
Mark's comments should help you.
If you are confused by dealing with inetcfg, though, try this old-timer method:
1) Start edit & open your sys:system\autoexec.ncf file
2) Using a semi-colon, REM out the line that loads initsys.ncf
3) You need 3 lines to establish IP communication (In my example, I'll assume that you are using a 3Com NIC, it's in PCI slot 2, & you have a 24 bit subnet mask):
a) load tcpip
b) load 3c90xc.lan slot=2 frame=ethernet_ii name=nic_1
c) bind ip nic_1 addr=192.168.0.x mask=255.255.255.0 gate=192.168.0.x
4) Save the file & reboot.
Good luck ------------
