  ext3 volumes can be mounted as ext2.  The main thing is that you don't
have journaling, but that isn't too important for read-only access.

  grub is a bootloader just like lilo is.  It can chainload into lilo
(that is, boot lilo from a partition as if the computer had booted into
it directly) or boot a Linux image directly.

  The usual command for booting from hda1 would be

root (hd0,0)
kernel /boot/vmlinuz-2.6.30-1-686 root=/dev/hda1
initrd /boot/initrd-2.6.30-1-686

  but of course they might need to be adapted for your situation.
