● Reset to Factory Settings (some models) (Do not reset/Reset) Resetting to factory defaults

 

will erase all security keys. Changing this setting requires turning the computer off and then

 

back on.

 

CAUTION: The embedded security device is a critical component of many security

 

schemes. Erasing the security keys will prevent access to data protected by the Embedded

 

Security Device. Choosing Reset to Factory Settings may result in significant data loss.

 

● Power-on authentication support (some models) (enable/disable) Controls the power-on

 

password authentication scheme that utilizes the Embedded Security Device. Changing this

 

setting requires turning the computer off and then back on.

 

● Reset authentication credentials (some models) (Do not reset/Reset) Selecting Reset

 

disables the power-on authentication support and clears the authentication information from

 

the Embedded Security Device. Changing this setting requires turning the computer off and

 

then back on

 

OS management of Embedded Security Device (some models) (enable/disable) This option

 

allows the user to limit operating system control of the Embedded Security Device. Changing this

 

setting requires turning the computer off and then back on. This option allows the user to limit OS

 

control of the Embedded Security Device. Default is disabled.

 

● Reset of Embedded Security Device through OS (some models) (enable/disable) This option

 

allows the user to limit the operating system ability to request a Reset to Factory Settings of

 

the Embedded Security Device. Changing this setting requires turning the computer off and

 

then back on.

 

NOTE: To enable this option, a Setup password must be set.

 

 

DriveLock Security

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.
