Drive Lock Security
Lets you assign or modify a master password or user password for hard drives.
When enabled, this feature prompts the user to provide one of the DriveLock
passwords during POST. If the user does not successfully enter one of the
passwords, the hard drive remains inaccessible until one of the passwords is
successfully entered during a subsequent cold-boot sequence.
NOTE:
This selection appears only when the system includes at least one drive
that supports the DriveLock feature.
