<DIV></DIV>> 
<DIV></DIV>>So where are you now? It seems like you have an SS/10 with another boot disk 
<DIV></DIV>>(why?) that can not reset the eeprom. 
<DIV></DIV>> 
<DIV></DIV>>I guess what you are trying to do is login to the machine as root user, then 
<DIV></DIV>>as root user get around the password protection in the eeprom and reset it, 
<DIV></DIV>>correct? 
<DIV></DIV>> 
<DIV></DIV>>It would seem to me that Sun would have thought of that option, and blocked 
<DIV></DIV>>it (put a signature in the drive tied to the password?) - can you boot the 
<DIV></DIV>>OS CD-ROM? Would that get you anywhere? 
<DIV></DIV>> 
<DIV></DIV>>What if you swap NVRAM/EEPROM for one without a password, then boot into 
<DIV></DIV>>root and switch chips while running? 
<DIV></DIV>> 
<DIV></DIV>>Or re-install the OS, then put back the protected NVRAM/EEPROM? 
<DIV></DIV>> 
<DIV></DIV>>You know, you can get a new (to you) SS/10 base for very little money, 
<DIV></DIV>>without a password in NVRAM... (SS/10 base for $45 at 
<DIV></DIV>>http://www.compsyscon.com/prod05.htm ) 
<DIV></DIV>> 
<DIV></DIV>>HTH, 
<DIV></DIV>>
