Re: [9fans] booting plan 9 from LILO (was matrox ...)

[Sam <sah@softcardsystems.com>]

I haven't set up lilo to boot plan9, but I have set up
lilo to boot windows from the second ide channel, which
windows doesn't willingly do.  It involved adding special
lines in lilo.conf to make windows think he was on the
primary channel.  I can't recall the precise magick, but
odds are you can google for it.

Alternatively, I believe you should be able to
change the line boot=/dev/hdX in your lilo.conf
file to point to the second drive, install the boot
block there, power down, swap the drives on your ide
chain and reboot.  Linux boots fine from the secondary
channel, if I recall correctly.  If you futz it up,
some flavour of rescue disk might be handy. ;)

If you're super brave, you could always poke around
in the lilo code until you find the undocumented feature
you're looking for. ;-X
