Just FYI you can also swap disks with LILO.
(I've not often seen it mentioned so I guess I'll say it aloud here)
Apart from the syntax that was a bit more evoluted than GRUB's it is
exactly the same.
It's something like this:
map-drive = 0x80 # Logically swap the drives so that when
they
to = 0x81 # are accessed via the BIOS, the second
drive
map-drive = 0x81 # will appear as the first and the
first as
to = 0x80 # the second.
(from http://www.wwnet.net/~stevelim/booting.html)
LILO's not dead (yet) :-)
