Reloaded, now can't see NIC

[Aribella]

I had to reload Redhat 6.2 (only 2nd time, still learning)
When I did "ifconfig" it didn't list lo or eth0. So I did ifconfig 127.0.0.1 and then
"ifconfig eth0 (my IP) and it say
SIOCSIFADDR: No such device
eth0:unknown interface: no such device

I have a 3Com 3C509B card installed. It had been working prior to my reload. Is there still some driver I still need? If so, where would I look? Are there other simple foolish things a newbie might do?

1- You must have support for networking and your 3c509 built into the kernel...which means that you may need to recompile it. Check out the nhf here...it is good.
2- Once you have support for that you will need to alias it in /etc/conf.modules as so:
alias eth0 3c59x
3- You will need /etc/sysconfig/network-scripts/ifcfg-eth0 containing:
DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.0.255
IPADDR=192.168.0.1
NETMASK=255.255.255.0
NETWORK=192.168.0.0
ONBOOT=yes

3- To start it then....run /etc/init.d/network start.

Or you can skip all but the kernel part and do it through linuxconf. I prefer editing the files though.
Hope it helps

Thank you Shaggy,
I looked at step 2 and I don't have the "alias eth0 3c59x". So back to step 1.
I read the NHF and it doesn't look that easy to compile and I think there's probably lots of new problems that I could introduce. So, want to be sure it's required, before I try to recompile. What things in the kernel should I be looking at? Can the kernel be accessed with vi?
