    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.

    Thanks again,
    Jim

    Hi there..

    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.

    Regards,
    Michael
