    If the BIOS has such an option, I haven't found it.

    Huh? Why USB?

    If I can't mod the BIOS, how will lilo know to update the
    /dev/hda MBR, to tell it that the OS, etc are on /dev/sda?

    rm it, or comment it out of lilo.conf?

    Yes, I definitely want to boot into the new system, not the
    old disk.

    But the BIOS wants to run the "old" lilo that's on /dev/hda,
    not the new lilo that's on /dev/sda.
