change hd0 to hd1 in /boot/grub/menu.list
- boot the disk after its been physiclly swapped on the cables ...
lilo# vmlinuz root=/dev/hda ( the new hda -- was prev hdb )
same for editing the grub cmd line to chanage root=/dev/hda
- any mbr info ( including floppy, cd, .. ) can boot into the rootfs
of the new swapped disk
- once its boot ... run lilo ...
- reboot again and now you dont need the other boot media
( cd, floppy or old hda to boot the new hda )
- or do it the hard way ..
chroot /mnt/new-swapped lilo --> leads to loads of fun
( you probably will still want a boot media to rescue
( the box if the new swapped disk doesnt boot
other stuff is too much work

if of is the new target disk, it will wipe out your partition table of
your new disk ( bs=446 or bs=448 is better ) if you want to preserve
the partitions on the target disk
