Overview of BIOS Features

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 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 hard disk
drive
password. After the third unsuccessful hard disk drive password attempt, the system
will halt with the message:
Hard Disk Drive Password Entry Error
A manual power cycle will be required to resume system operation.
NOTE
As implemented on DB85FL, Hard Disk Drive Password Security is only supported on
SATA port 0. The passwords are stored on the hard disk drive so if the drive is
relocated to another SATA port or computer that does not support Hard Disk Drive
Password Security feature, the drive will not be accessible.
NOTE
Hard Disk Drive Password Security is not supported in PCH RAID mode.
Secured hard
disk drives attached to the system when the system is in PCH RAID mode will not be
accessible due to the disabling of BIOS Hard Disk Drive Password support.

BIOS Security Features
The BIOS includes security features that restrict access to the BIOS Setup program
and who can boot the computer. A supervisor password and a user password can be
set for the BIOS Setup program and for booting the computer, with the following
restrictions:
•
The supervisor password gives unrestricted access to view and change all the
Setup options in the BIOS Setup program. This is the supervisor mode.
•
The user password gives restricted access to view and change Setup options in the
BIOS Setup program. This is the user mode.
•
If only the supervisor password is set, pressing the <Enter> key at the password
prompt of the BIOS Setup program allows the user restricted access to Setup.
•
If both the supervisor and user passwords are set, users can enter either the
supervisor password or the user password to access Setup. Users have access to
Setup respective to which password is entered.
•
Setting the user password restricts who can boot the computer. The password
prompt will be 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, the user can enter either password to boot the computer.
