1. Make a boot floppy.  mkbootdisk `uname -r`

Have a look at /etc/fstab.  If all the first column are partition
labels and not /dev/hdb* (not counting swap and "none" entries), then
skip to step 3, and then to step 7.  You ought to do step 2 anyway,
just to have a rescue floppy.

2. If you can, make a stand-alone boot disk, say, using Tom's Root and
   Boot:

   http://www.toms.net/rb/

3. Shut down the machine.  Move hda to hdb.  Don't forget to change
   the jumper(s).

4. Boot with toms-root-boot.  Mount the root partition on /mnt.  (say
   it's /dev/hda2): mount /dev/hda2 /mnt

5. Edit the fstab to change all /dev/hdb to /dev/hda.
   vi /mnt/etc/fstab

6. Unmount it and reboot:
   umount /dev/hda2
   shutdown -r now

7. At the boot: prompt, put
   linux root=/dev/hda2

   Hmm.  Now that I think of it, if /etc/fstab has labels, I think you
   can just boot without putting anything there.  (I don't use labels,
   but for a very good reason.)

8. After it boots up, then modify /etc/lilo.conf and re-run lilo.

Ok, Rick.  What did I forget or get wrong? ;-)

Cheers,

Linux: because I want to get there today.  Without rebooting.
