I could not boot from a (Sun) DVD -- most disturbing.  So I tried 
booting from disc again.  This time, I was told of a memory error and 
advised to run "fmadm faulty".  The latter told me.

Fault class : fault.memory.bank 95%
Affects     : mem:///unum=DIMM0,DIMM1
                   faulted but still in service


I will try replacing these two DIMMs and see what happens.
