Yes. According to the documentation, that would be correct. On my
systems, it isn't.

Cool. Thanks for the tip.

Here's the scoop. I reinstalled from the second machine using the
same steps as the first time. It booted OK. So, it's running
multi-user, booting from a GRUB floppy. The numbering is still
strange as this device is *still* numbered hd2 even though there are
no other IDE hard drives in the machine.
