How to Require a Password for Hardware Access

1. Become superuser or assume an equivalent role.

2. In a terminal, enter the PROM security mode. Type the following:

   # eeprom security-mode=command Changing PROM password: New password: password Retype new password: password

   Choose the value command or full. See the eeprom(1M) man page for more details.

3. If you are not prompted to enter a PROM password, the system already has a PROM password. To change the PROM password, run the command:

   # eeprom security-password=<Type the Return key> Changing PROM password: New password: password Retype new password: password

   The new PROM security mode and password are in effect immediately, but are most likely to be noticed at the next boot.

   Caution –

   Do not forget the PROM password. The hardware is unusable without this password.
