Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can
be accessed and who can boot the computer. A supervisor password and a user
password can be set for the BIOS Setup and for booting the computer, with the
following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup
options. If only the supervisor password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the
supervisor password or the user password to access Setup. Setup options are then
available for viewing and changing depending on whether the supervisor or user
password was entered.
• Setting a user password restricts who can boot the computer. The password
prompt is displayed before the computer is booted. If only the supervisor
password is set, the computer boots without asking for a password. If both
passwords are set, you can enter either password to boot the computer.

Trusted Platform Module (TPM)
The TPM 1.2 device is designed to enhance platform security above and beyond the
capabilities of today’s software by providing a protected space for key operations and
other security critical tasks. Using both hardware and software, the TPM protects
encryption and signature keys at their most vulnerable stages—operations when the
keys are being used unencrypted in plain-text form. The TPM is specifically designed
to shield unencrypted keys and platform authentication information from software-
based attacks.
For information about enabling and activating the TPM, refer to the Trusted Platform
Module (TPM) Quick Reference Guide .
