How to Protect Machine Hardware

For security, access to the PROM should also require a password.

SPARC: To Set the PROM Mode and Password

    As root, label admin_low, in the profile shell, enter the PROM security mode.

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

      You are prompted to enter and confirm the PROM password.


      # eeprom security-mode=command

Changing PROM password:
	New password: password
	Retype new password: password

    2. If are not prompted to enter a PROM password, the workstation already has a PROM password. To change it, 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 rendered unusable without it.

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

IA: To Protect the BIOS

On an Intel machine, the equivalent to protecting the PROM is to protect the BIOS . Refer to your machine's manuals for how to protect the BIOS.
