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 be either a PCI expansion
card or embedded on the system board.)
Allows you to set:
● Asset tag (18-byte identifier), a property identification number assigned by the company to the
computer.
●
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.
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.
See the Desktop Management Guide for more information.
