I think he means the device that will be used at the next boot (where
"device" can be network), which is of course a BIOS question.  He may be coming
from AIX where there is a command to query and set the boot device list in the
BIOS config.

Such a utility is easy with openfirmware.  It is feasible with proprietary
firmware, but has to know about a lot of variations on CMOS layout.
