    Your problem is not LVM. Ignore it (unless your root is on LVM, in which
    case, *all* your kernels better have initrd images capable of booting off a
    LVM root). This is a separate issue from anything LILO-related.

    SATA disks under libata (2.4.27 for most controllers, 2.4.28-pre1 for Intel
    ICH, and everything in 2.6.8) show up as scsi disks. Unless the controller
    is in some weird "legacy compatibility" mode.

    Switch your 2.4.x kernel to 2.4.28-rc3, with libata support.

    Try /dev/sd(a|b), depending if you want to access the first or second SATA
    disk.

    It is a good thing LILO is smarter these days. Given the amount of
    misleading documentation that tells people to install lilo boot sectors
    inside their filesystems, it is no wonder it had to.
