Michael, Thanks for your help with this. /etc/modprobe.conf showed "alias eth0 e100" but lsmod did not show the e100 module loaded. I tried running "modprobe -v e100", but I got an error message indicating that the e100 module could not be found, even though the file existed: /lib/modules/2.6.9-5.EL/kernel/drivers/net/e100.ko. I ran depmod to load dependencies, then modprobe -v e100. The module loaded and lsmod now shows e100 loaded. When I restarted networking (service network restart) the eth0 interface came up.

I have encountered this before. I managed to fix it by editing the /etc/sysconfig/network-scripts/ifcfg-eth0 file, and removing all lines that have a defined MAC address. ie the lines : MACADDR= or HWADDR= Also check that lsmod shows the device's kernel module loaded ok - check the /etc/modprobe.conf file for alias eth0 <kernel module>, and see if that module is loaded ok in lsmod.
