Keep in mind that I don't mess with scsi much. Sounds like the first
step would be to make sure that you can get to the drives. I have not
had to do this with a scsi drive and don't remember off hand what tom's
does to mount hard drives. Fist look to make sure the card is seen.
My guess is that you will need to load the module for the adaptec card.
It looks like it is the aic7xxx.o.Check to see if it is loaded first:
as root try :
lsmod
this should list all the modules loaded.
if nothing like this is listed then lets try and load it:
insmod aic7xxx.o
with any luck it will be loaded lets look:
lsmod
if you see it, we're jammin'
now you should be able to create a directory and mount your drives.
cd /
mkdir /win
mkdir /linux
mount -type ext2 /dev/sdb1 /linux
now you should be able to lookaround on the /linux directory tree and see
all your stuff.
OK so far? Now we get even more over my head. The issue I am uncertain
about is whether or not lilo needs to have a device mounted inorder to
install itself. I am assumming that it needs to be installed on the
first scsi device where your windows lives. Makes sense to me or windows
will continue to load first. If your setup was working it looks like to
me from the lilo docs that doing a
lilo -r /linux -v
will chroot to your newly mounted linux partition and then do the lilo
thing. as I said, I just don't know for sure what mbr lilo will write
to. I don't have time to read the docs but am curious.
This is the procedure that I would try, but as I said I have not had to
do this (yet) so lett me know how it goes. Maybe someone else will jump
in here and give you a hand that has had to do this before and take some
of the guess work out of this.
