[rescue] Ultra 5/10 with OpenPROM Password

[J. Alexander Jacocks]

I have an opportunity to get rather cheaply either an Ultra 5 or Ultra
10 with a set, unknown PROM password.

Anybody here know an easy way to break one of these?  The only options I
am aware of involve ordering a new one from Sun, or hot-swapping a
module from a system with a good PROM.  The second option would be
difficult, because I don't have any other U5/10's.

Thanks!
