Reading the BIOS code, my understanding is that 'boot from hard disk' means
to boot from the first connected hard drive enumerated in the following
order: primary master, primary slave, secondary master, secondary slave
(i.e., hda-hdd). I confirmed this with a few simple tests -- attach a
bootable image to hdd boots fine, but if I connect a non-bootable image on
any of hha-hdc then the system fails to boot. This is all entirely
deterministic. Selection of boot device should not be random, nor change
across reboots.
