which architecture?

with x86 it is impossible to determine from what device the current
system has booted, and it is very difficult to guess which device will
be used to boot next time, this is why grub uses a device map to
associate bios hard disks to devices, which is configured at install
time.

On different arches you could have some interface to query nvram.
