Device Security
Enables/disables serial ports, parallel port, front USB ports,
system audio, network controllers (some models), and SCSI
controllers (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).
• 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 (some models)
Allows you to assign or modify a master or user password for
certain ATA 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 ATA Security is attached to the system.
