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.)

System ID entry.
DriveLock Security Allows you to assign or modify a master or user password for drives
that support ATA Security. 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.
