Protecting the Machine

For more information on PROM values that you can set, see OpenBoot 2.x Command Reference Manual or OpenBoot 3.x Command Reference Manual.

SPARC: Protect Machine Hardware

    In the terminal, enter the PROM security mode. 


    # 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.

    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=Return
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 - Caution -

    Do not forget this password. The hardware is unusable without it.

IA: Protect the BIOS

On Intel architecture, the equivalent to protecting the PROM is to protect the BIOS.

    Refer to your machine's manuals for how to protect the BIOS.
