What do you mean by disable? Removing the device or preventing it from connecting to a netwotk?

You did not tell us your distribution, but assuming it is RedHat or SuSe, edit /etc/network/interfaces and comment the right eth0 device.

Solution 2:
Create/edit the udev rule in /etc/udev/rules.d/70-net... (complete de name with tab)

To just disable internet and shut the interface down: ifdown <interface name>

In my BIOS...

Assuming that you have an on-board LAN device, there should be a post in the BIOS settings to disable the chip function; mine is "On-chip MAC Lan" Look for something similar and disable it.

However, since this is a server and network connection is assumed, there may be no BIOS control of the LAN. Your IBM system/motherboard documentation might tell you more.

If you have a separate LAN card, there should be nothing in the BIOS about it as a LAN; it should be found as one of the PCI devices. Simply remove the LAN card.

RedHat has configured the device. In my openSUSE 11.1 installation, I can open the configuration process and re-configure or disable a LAN device and its connection. I assume that you can do the same in RedHat. I don't know which RedHat you are using, but RedHat is generally well documented. This is for RHEL 5.

Of course you can edit files, but I assume that configuring the installation would be more logical and create fewer difficulties in the end than by editing.
