Sorry about the loud text! I feel that a lot of people are not really
listening. I can't get to the monitor.  After the system checks, the 4/110
tries to boot from sd(0,0,0) then bounces to the PROM:pass requirement.  I
have tried to access via ttya in diagnostics mode but after system checks I
get locked out there as well (clever little PROM).  I do not have the
original disk drive that was with the system and so I can't boot into it
and enter as root to change the eeprom that way.  I have tried to boot a
disk with Solaris on it I made on my Sparc 2 but it will not boot for some
reason.  I may end up de soldering the chip extracting the data, writing it
to another (sans the password) and reinstalling it (of course I would put a
socket in there just in case).
