used mostly for archives.

What is "SCSI BIOS 2.20"? How old is "much older"?

Computers often save memory or address space by counting from 0 instead
of one. Any human interface to a process that does this should shift
such counts up by one, but very commonly they don't.

How old are your motherboard and its BIOS?

Modern BIOS try to be smart, but many fail. Typically they allow you to
set particular drives to show up in a particular order, but many will
rearrange things if you add, remove, or rearrange physical drives, or
do anything to make the BIOS think things have been rearranged.

A particular problem involves SATA and USB devices, usually worst with
Linux. Linux pretends SATA devices are SCSI devices, and usually
pretends USB devices are SCSI devices as well. When you really do have
real SCSI devices, Linux can be really stupid about drive assignment
order. It seems eCS/OS2 may not be perfect in this regard either, and
doze is just too unpredictable to predict what it will do in every case
of multiple devices.

With modern BIOS, it helps to stick to only one HD type, but that's not
always so easy with the convenience of HDs attached via USB. Devices
really need to be mounted only by label any more to insure against
unwanted rearranging in multiple device environments. This is pretty
much what XP and LVM do. Linux can too, but rarely does it by default.
