The problem isn't that the BIOS is booting the wrong drive. The BIOS
is booting the correct drive, grub is starting, grub is loading the
correct kernel. When the _kernel_ runs it (sometimes) identifies disk
drives in the wrong order and tries to mount the root directory from
the wrong drive.

This has nothing to do with what disk drive the BIOS tries to boot
from (there's no problem with that).
