Can't say about the SS1, but certainly doable for later systems
like the Ultra1 I did the other day.  http://docs.sun.com is a very
handy site.  I searched for OBP I think and soon found the page I 
needed.

Actually, now I think of it, you'll likely need a new ROM for your 
SS1, since I did for my SS20 to handle hypersparc cpu's.
