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. -- Stuart D. Gathman Business Management Systems Inc.
