Just to be complete, I should mention that what I had done was
taken the one disk that had been the only disk, moved that to
be the slave disk and added a new disk as the master ATA disk.
I then installed 5.1 onto the new "disk0".
So I know the "new disk1" used to work as the old disk0, but it
is true that the disk was built and had always run as disk0
before I added the second disk to the machine.
