On a suitably new Sun system (Ultra 1 and newer?)  You no longer need to
change the BLOCK jumper, they can boot from 2048 block drives just fine.
That was mainly a limit with older Suns (4m/c/older) and other non-pc
workstation/server class stuff (like HP & VAX).

Then you shouldn't need to mess with any other jumpers.
