If you have set up a firmware password on a Solaris based machine and you cannot remember what the password is, allow the machine to boot all the way into the O/S, and then open a terminal window. Type “eeprom security-mode=none”, (just the words, not the quote marks). This will nullify the firmware password. If you wish to put a new password on the firmware, type “eeprom security-mode=command”. You will then be asked for the new password. The eeprom command is a good way to change your machines NVRAM configuration while in the O/S, instead of rebooting the machine. Just use the “man eeprom” command in the terminal to see all the uses for this command.
