Look at them :-) Actually the 3/110 just predates the OpenBoot stuff. While
there is some forth buried in there somewhere its not to easy to find.
Generally on the 3/110 there were *no* internal devices so if nothing is
hooked up then there is nothing to boot from.

Typically the three boot choices were:
        xy() - boot from SMD drive
        ie() - boot from the net
        sd() - boot from a scsi disk.
The standard scheme is device(channel, unit, subunit)file
since you probably don't have multiple interface cards channel will always
be 0, unit is typically '3' for SCSI disks, or 6 for SCSI CD roms, XY use
unit 0 or 1 typically. And subunit if you've got multiple devices on a
controller (SMD drives often had two so you had xy(0,0,0) and xy(0,0,1))
