Subject: Booting a Sparcstation from disk

[Apologies if you've already seen this]

I've got my SLC booting from disk.  The command ss/home will set up
a new boot disk (takes about 24 mins).  Caveats:

- boot disk must be scsi id 3 for the ROM monitor to boot from it
- disk probably needs to have been formatted by sunos/solaris, which stores
   a lot of pointless information + a checksum in sector 0, which I have been
   leaving alone.  If this becomes a problem, I can probably provide a "blank"
   sector 0 (there's a magic number, so it can't just be all zeros)
- only V1 of the ROM monitor is supported.  The ELC's are V2.  I will
   probably fix this at a later date.  Apparently a V0 exists also...

P.S.  You really don't want to know how it works! ;-)
P.P.S. Danger!  The other "home" scripts are unaware that the interface to
    disk/prep has changed...
