Hard Disk Drive Password Feature During BIOS POST

During every BIOS POST execution, if a User hard disk drive password is present on
the hard drive, POST execution will pause to prompt the user to enter the Master or
User password:
Enter Hard Disk Drive Password:
Upon successful entry of the Master or User hard disk drive password, the system will
continue with normal POST.
If the hard disk drive password is not correctly entered, the system will go back to the
above prompt. The user will have three attempts to correctly enter the correct hard
disk drive password. After the third unsuccessful attempt, the system will halt with
the following message:
Hard Disk Drive Password Entry Error
The BIOS will then lock the drive from further activity, requiring a power-cycle to re-
attempt hard disk drive password entry.

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.
