The manual hunt....

for a in 1 2 3 4 5 6
do
 mkdir /mnt/test$a
done

mount /dev/hda1 /mnt/test1
mount /dev/hda2 /mnt/test2
...

Hopefully mount will automatically identify the partition type and do
the right thing.

The "chroot /mnt/testN", "lilo".

If you mess up the chroot you should be able to "ctrl+alt+Function key"
to get a new window, and either kill the process that is the chroot, or
just try again in the new window (don't run out).

My blog entry might be handy - although it is for a mirrored pair,
hopefully it will inspire you to realise that I forget to run lilo at
crucial points to, which is why I run grub as much as possible. Lilo is
actually easier to set up first time for mirrored disks, but you pay for
it every kernel upgrade you forget to run lilo.

Note I have the good sense to exit the chroot, and umount the disk
(which flushes outstanding writes) before I hit the power button. Which
I forgot to mention above.
