The way to tell is to (from OpenFirmWare's "ok" prompt) cd to the
device, and type "words" - if you see a series of OF routines like
"open" "close" etc, you should be good to go for booting from that
device. Macs (particularly the first PCI/PowerMacs) don't have very
extensive OF support, so something like "probe-scsi-all" might not be
supported - it probably requires a "word" that is sun-specific (or is
listed as optional in IEEE 1275).
