System Management
Allows authorized personnel to reset security settings during a service event. Default is enabled.
Command
Restore Security
This action resets security devices, clears BIOS passwords (not including DriveLock), and restores settings
Settings to Default
in the Security menu to factory defaults.
NOTE:
Most operating systems control access to the MBR of the current bootable disk; the BIOS
cannot prevent changes that may occur while the operating system is running.
Restores the backup Master Boot Record to the current bootable disk. Default is disabled.
Only appears if all of the following conditions are true:
–
MBR security is enabled
–
A backup copy of the MBR has been previously saved
–
The current bootable disk is the same disk from which the backup copy was saved
CAUTION:
Restoring a previously saved MBR after a disk utility or operating system has modified
the MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved
MBR if you are confident that the current bootable disk's MBR has been corrupted or infected with a
virus.
Save/Restore GPT of System Hard Drive
Enabling this feature will save the GUID Partition Table (GPT) of the system hard drive. If the GPT is
subsequently changed, the user is prompted to choose whether to restore GPT.
DriveLock/Automatic DriveLock
Allows you to assign or modify a master or user password for hard drives. When this feature is
enabled, the user is prompted to provide one of the DriveLock passwords during POST. If neither is
successfully entered, the hard drive will remain inaccessible until one of the passwords is
successfully provided during a subsequent cold-boot sequence.
NOTE:
This selection will only appear when at least one drive that supports the DriveLock feature
is attached to the system.
CAUTION:
Be aware that these settings take place immediately. A save is not necessary.
CAUTION:
Be sure to document the DriveLock password. Losing a DriveLock password will render a
drive permanently locked.
After you select a drive, the following options are available:
Set DriveLock Master Password. Sets the drive's master password but does not enable DriveLock.
Enable DriveLock. Sets the drive's user password and enables DriveLock.
Secure Erase
Lets you select a hard drive to completely erase.
Once a hard drive has been erased with a program that utilizes Secure Erase firmware commands, no
file recovery program, partition recovery program, or other data recovery method will be able to
extract data from the drive.
Allow OPAL Hard Drive SED Authentication
Default is disabled.
