Hard Disk Drive Passwords
NOTE
On this board, the Hard Disk Drive Password Security feature is only supported on
SATA port 0. Since the passwords are stored on the hard disk drive, if the drive is
relocated to another SATA port or computer that does not support the Hard Disk Drive
Password Security feature, the drive will not be accessible.
The board’s Hard Disk Drive Password Security feature blocks read and write accesses
to the hard disk drive until the correct password is entered. Hard disk drive passwords
are set in BIOS Setup and are prompted for during the POST. For convenient support
of ACPI S3 resume, the system BIOS automatically unlocks drives on resume from S3.
The User hard disk drive password, when set, will be required upon each power cycle
until the Master Key or User hard disk drive password is entered.
The Master Key hard disk drive password, when set, will not lock the hard disk drive.
The Master Key hard disk drive password is an unlock override that can be used in the
event that the User hard disk drive password has been forgotten. Only the installation
of the User hard disk drive password will cause a hard disk drive to be locked upon a
system power cycle.
Table 4 shows the effects of setting the
hard disk drive passwords.

During every POST, if a User hard disk drive password is set, POST execution will
pause with the following prompt to force the user to enter the Master Key or User hard
disk drive password:
Enter Hard Disk Drive Password:
Upon successful entry of the Master Key or User hard disk drive password, the system
will continue with the normal POST.
