Greetings. I'm trying to reinstall a NetBSD/hp300 system that
managed to hose its root partition (lost the init binary). I've
managed to track down a bootable HP/UX disk to bootstrap the
reinstall, but the disk makes all sorts of wrong assumptions about the
network and dosen't come up into a useful state. The system has two
HP-IB interfaces and a network interface, but no tape or removeable
media beyond the silly dual-floppy drive.

Questions:
    Is there a way to make the HP/UX boot go to a single-user
mode? That would let me reinstall, though putting stuff on the disk in
a NetBSD-happy way from HP/UX will prove interesting. 
    If the disk with NetBSD installed is attached at boot time, I am
unable to prevent the machine from trying to boot from it. Is there a
way (beyond amazingly timed typing in the startup probe) of preventing
this? 
    The machine has a 'Rev B' PROM. Does this render net-booting
completly unfeasable? I haven't had a chance to test it yet.
    And as long as I'm at it, is there a decent general reference to
HP300 hardware, on the order of the Sun hardware FAQ? I have a huge
pile of machines which I would love to make functional if I only knew
what half the pieces were.
