Network Interfaces detected, but not active. [Solved]

I am looking for help getting my network cards up and running in a fairly new install. Sadly its a brand new machine so I do not have any instances of the network cards working to go off of except the livecd. I was viewing a few threads on the issue, but I haven't yet gotten anything to work and thought I would look for some help.

kernel-genkernel-x86_64-2.6.20-gentoo-r8

I generally use the genkernel to get a system off the ground. Optimizing the kernel config for future revisions after everything is set up. I have taken the time to get some information asked for in other threads in hopes to be as informative as possible.

A little background
The system is an Asus P5N32-SLI Premium and a Core2Duo the chipset for the board is an NForce590i with dual gigbit ethernet jacks on the backside. I also have 2 IEEE1394 ports attached the motherboard and the genkernel comes with Ethernet/IEEE1394 enabled (but lacked my sata driver support by default go figure)

In the liveCD eth0 and eth1 are the gigbit ports while eth2 and eth3 are the 1394 ports. In the genkernel the numbers are reversed 0 and 1 being the 1394 ports and the 2&3 the ethernet. This is determined by the mac adresses as 1394 ports macs are sufixed with several zero's

I have tried to bring up eth2 and eth3 manuall and apply dhcpcd. When this did not work I assigned eth2 192.168.1.9 an available address at the time then added a route to my gw. The resolv.conf points to the gw already

cat < resolv.conf

Ifconfig.livecd

I had to take a break on this one for a few days. Sitting in front of it now and can't seem to think of anything. Does anyone know if its possible that the new drivers are asking for an ip6 address and the router can't handle it? I am manually assigning ip4 address using ifconfig and adding an ip4 route using route.

However I am still dead in the water.

I had to do three things to fix this on my manually configured & compiled 2.6.21-gentoo-r3 kernel, using the same motherboard (MCP55 chipset) - note, I don't have any firewire devices, so my controller is disabled in the bios (shouldn't be relevent tho)

It's not the router; assigning fixed IPs just disguises the problem. You can use ethtool to check the network card - ethtool eth0 shows it working on the livecd, but not on my manual kernel - you'll probably find the same. (link not detected, that sort of thing)

Anyway, what I tweaked.

1) compile forcedeth driver (nvidia network) as a module:
device drivers\network device support\ethernet (10 or 100mbit)\nforce ethernet support
(it does have Gb support, even though its not listed under the 1000Mb list)

2) added

This solution solved my problem. Thank you for the help. I am going to post this for a friend that had the same problem in another thread. Thank you for your help sorry I did not reply sooner.
