I have an ASUS M2NPV-VM motherboard and I am using CentOS 4 and my kernel version is 2.6.9-22.EL. I have not been able to get the onboard lan adapter to be recognized so that I can use it. When doing an lspci I see the 00:14:0 Bridge: nvidia Corporation MCP51 ethernet controller (rev a3). I also have another ethernet card that does show up as eth0 and it works.
In my /etc/modprobe I have alias eth1 forcedeth
In my /var/log/message I see forcedeth.c: Reverse Engineered nForce ethernet driver. Version 0.30.

When I check lsmod there is no forcedeth there.

What steps do I need to perform to get the onboard lan to work?

Thank you in advance.

It seems you'll need to download and install a driver for that particular NIC. Your best bet would be the Nvidia website. Also, you are using a rather old kernel. Maybe a newer kernel has support for the NIC?

If you are not going to upgrade your kernel though, your only option is to try and find a driver for that NIC, download and install it. At least, that should be the first step. You will then of course need to configure the NIC (once you have access to it) with the correct ifup commandline to ifconfig.
