Ahhh. Now that makes sense. :-)

Oops. I am a SCSI-head. I don't normally use IDE but I am giving
ATA66 a whirl on my workstation. Because of my predominant use of
SCSI /dev/sd* is what I am used to dealing with. Of course I meant
/dev/hda1 rather than /dev/sda1

It's not so much the boot sector I am worried about. What concerns me
is that when I set up my new disk (on /dev/hdc1) with LVM, LVM is
associating the device /dev/hdc1 with the PV. What happens to that
association when I move the disk to the primary ide bus and it becomes
/dev/hda1?

Everything that is needed for LVM you mean or do you mean you copied
everything from your root filesystem? If the latter, would that not
be overkill?
But I like the idea. I was thinking it was time to move on from
emergency boot diskette(s) to a boot CD-ROM.
