    I guess the problem is that, by default, Mandrake creates an extended partition
    when installed, where all the other partitions go.

    Whenever I install Mandrake, I'm always careful to switch to "Expert" mode and
    configure the partitions to be primary by hand to avoid this kind of problems.

    If you are a corageous hacker, you can always:

      - boot from a CD distribution (knoppix, etc.)
      - run fdisk on your hard drive
      - take note on the cylinders being used by the partitions,
      - delete the partitions on the extended partition, and the extended partition
    itself
      - create the partitions again as primary using the *exact* same cylinders
      - write the partition to disk
      - reboot

    Probably you'll have to adjust fstab to use the new partitions, but at least 2.4
    and 2.6 should both agree that you have an hda :)

    I don't know if you'll need to run lilo again before rebooting, but I would do
    that just to be on the safe side. To do that:

      - mount /dev/hda somewhere (/mnt/disk or something)
      - # cd /mnt/disk
      - edit etc/lilo.conf to always use /dev/hda
      - # chroot . lilo

    I hope this helps,
