no ethernet after install

I just installed from I live CD and on reboot it tells me that eth0 does not exist. Does anybody know where I might have gone wrong?

The driver for your NIC may not be compiled as a module or in the kernel.

check your kernel config.

Or if that's not it did you edit /etc/conf.d/net?
And have you done rc-update add net.eth0 default?

I did edit /etc/conf.d/net and I have done rc-update add net.eth0 default. On startup it tries to start up eth0 but fails. I think that missed something when I compiled my kernel but am not sure what I need. I have a nVidia nForce2 Ethernet Controller. I did find a Reverse Engineered nForce Ethernet support (EXPERIMENTAL) as a kernal configuration option, is this what I need or is there something else?

Yes, this is what you need.

The module will be called forcedeth

Thanks that fixed it for me.

You're welcome.

I have the same ethernet controller but I don't see forcedeth or Reverse Engineered nForce Ethernet Support (Experimental) anywhere in the Kernel Configuration menu. Could the driver be called something else? Or perhaps there's a module somewhere that I need to install?

I'm pretty sure I don't have the driver installed since I got this message:

Make sure that you have "EISA, VLB, PCI and on board controllers" enabled, if not, you will not be able to see the "reverse enginnered" driver.

Thanks! I found it right after my last post but I couldn't find my way back here to update my post.

I had to compile the driver as a module and add it to the /etc/modules.autoload.d/kernel-2.6 file. It took me a few tries to get the syntax on that file too. At first I thought I had to type the pathname to the driver but all I had to type was forcedeth.

Now it works fine. Thanks guys.

My problem is different, however it is related.
I installed my system (amd64) and rebooted successfully, if I have a look at dmesg eth0 exists and is associated with the correct nic (nforce4 ethernet) however if I type ifconfig no nic is shown whatsoever except for lo. The same happens if I add marvell yukon driver (my mobo has two nics: Asus A8N-SLI deluxe).
I tried compiling forcedeth in kernel and as module, both give the same results.
I may add that I pass "noapic" to the kernel at boot, as otherwise I'd have trouble booting because something is not working in my apic.
I wonder if I'm missing some kernel options. Ideas?
