Hint 1: DONT hotswap it.  Swapping with power off is OK, but I've nuked 
ever single one I've tried doing the pull/login/put back in trick that 
works for sparc 5's.

Hint 2: Sparc 5s, 20s, and maybe 10s (and other models) use the same 
exact PROM.  Find $0 dead SparcStation 5, pull its prom, and use it in 
the U5.
