This looks like diag-mode.  Which is often an indication your NVRAM
went south, but not always.  I've never seen an Ultra NVRAM go flat
before, but all the sun4c and sun4m machines I've seen with NVRAM]
problems specifically mention the battery and/or TOD clock are bad.

Check the messages for that warning...

If it's in diag-mode, it would take a lot longer.
