    1. Boot to the DVD / cd #1

    2. select rescue

    3. If asked for your language select what is right for you.

    4. Make sure that you load any/all modules for the FS that you use.

    5. Continue to boot to the rescue system.

    6. At the login prompt use root for the login.

    7. fsck any filesystems needing repair.

    Additional tasks that can be done from here

    mount your / filesystem to /mnt i.e.: mount /dev/hda# /mnt (use the number
    that is correct for your installation.

    cd /mnt

    chroot /mnt

    mount any additional filesystem you need, i.e.: /boot if on a seperate
    partition.

    At this point you can add and remove packages using rpm manually even
    kernel versions and sources required if you move your harddrive to another
    MB using a different processor.

    Run mkinitrd to create the boot environment.

    -----------------

    I require a special module to access the Ultra ATA 100 raid controller
    which is -not- provided by SuSE (or any other linux supplier) because it
    is not 100% opensource and I need to compile my own module which I can do
    in the above rescue mode and then add the module to the /lib/modules tree
    so I can boot using it.

    Another command I have found to build the modules tree so that mkinitmd
    will build the tree is:

    depmod.old -a <kernel version (2.4.166-default)> -f
    /boot/System.map-<kernel version>.

    meaning I can be running the .144 kernel version and build the modules.dep
    file for the .166 kernel which is needed to run mkinitrd for the .166
    kernel that I want ot boot to.

    Sorry to get so long winded but wanted to pass on some of my experiences.
