Restoring Lilo
If you ever want to install Windows XP on a partition next to your linux installation be aware of the fact that it will overwrite your bootloader. No big problem as long you have a rescue disk or e.g. a knoppix cd at hand. All you have to do is to chroot and call lilo again.
> mount -o dev /dev/hda5 /mnt/hda5; chroot /mnt/hda5
> vi /etc/lilo.conf # fix if needed
> lilo
