Security
(continued)
Embedded
Security (This menu
only appears after
the Embedded
Security Device is
made available
under Device
Security)
Allows you to:
• Enable/disable the Embedded Security device.
• Reset the device to Factory Settings.
• Enable/disable power-on authentication support (some
models).
• Reset authentication credentials (some models).
This feature is supported on some models only.
Device Security Enables/disables serial ports, parallel port, all USB ports, front USB
ports, system audio, network controllers (some models), and
embedded security device (some models).
Network Service
Boot
Enables/disables the computer’s ability to boot from an operating
system installed on a network server. (Feature available on NIC
models only; the network controller must reside on the PCI bus or be
embedded on the system board.)
System IDs Allows you to set:
• Asset tag (18-byte identifier) and ownership Tag (80-byte
identifier displayed during POST).
• Ownership Tag. This tag is a string that is displayed under the
POST splash screen that can be used to identify the owner of
the computer.
• Chassis serial number or Universal Unique Identifier (UUID)
number. The UUID can only be updated if the current chassis
serial number is invalid. (These ID numbers are normally set in
the factory and are used to uniquely identify the system.)
• Keyboard locale setting (for example, English or German) for
System ID entry.
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.
✎ This selection will only appear when at least one drive that
supports the DriveLock feature is attached to the system.
OS Security (some
models)
✎ This selection is in effect only if the processor and operating
system being used comprehend and utilize this feature.
• Data Execution Prevention (some models) (enable/disable).
Helps prevent OS security breaches.
• Intel Virtualization Technology (some models) (enable/disable).
Changing this setting requires turning the computer off and then
back on.
