That's "linux root=/dev/hdc"

Well, I cannot comment on how reiser will change things, but the big
things you'll need to change are /etc/fstab and /etc/lilo.conf.
Because once you get past the boot command above you're going to hang up on
fstab referencing the wrong partitions.
One way to make this work is somewhat involved:
power off (obvious, but hey ;-)
remove the cdrom and install any old ide drive as hdc. (you COULD simply move the
cdrom to
where its going to end up, but that adds one more change that I wanted to
avoid)
boot up - everything SHOULD still work.
log in as root and:
fdisk -l /dev/hdb
fdisk /dev/hdc
now make /dev/hdc have the same PARTITIONS (not necessarily the same
SIZES)
as /dev/hdb (that's the reason for the fdisk -l above)
# make directories as required for those partitions, mount the partitions on
# those directories, and copy over /bin, /sbin, /etc, and whatever else you
end up needing
# to be able to boot on that drive.
halt # the truly paranoid would unmount everything first ;-)
change the drives around (the new temporary disk switches to hdb, the old hdb goes to
hdc)
boot off your recovery floppy onto hdb (repeat the above steps till this works. An
alternative
would be to simply INSTALL (a minimal) linux on that new drive and proceed to
the next step.
For discussion purposes, I'm going to assume your previous setup had /dev/hdb1 mounted
as /,
/dev/hdb5 mounted as /boot (just to show a second filesystem), and /dev/hdb6
as swap.
log in as root and:
mkdir /mnt/hdc{1,5}
mount /dev/hdc1 /mnt/hdc1
chroot /mnt/hdc1
mount /dev/hdc5 /boot
# if you have trouble running vi in the next step, do it before the chroot.
vi /etc/{lilo.conf,fstab} # (or emacs, or xemacs, or ....)
# then add an entry in lilo.conf for linux on /dev/hdc1
# save and exit
# if you have more than one partition, you may need to have them mounted (See
above)
lilo # see above note if this fails.
umount /stuff
exit # to get out of chroot
umount /dev/hdc1
reboot # and see if it works, its supposed to ;-)
I *think* that will do it, but beware this was typed from memory and YMMV!
