Restore Master
Boot Record* Restores the backup Master Boot Record to the current bootable
disk.
NOTE: Only appears if all of the following conditions are true:
MBR Security is enabled.
A backup copy of the MBR has been previously saved.
The current bootable disk is the same disk from which the backup copy
of the MBR was saved.
Ä
Restoring a previously saved MBR after a disk utility or operating
system has modified the MBR may cause the data on the disk to
become inaccessible. Only restore a previously saved MBR ifyou
are confident that the current bootable disk’s MBR has been
corrupted or infected with a virus.
Device Security* Enables/disables serial ports A and B, parallel port, front USB
ports, all USB ports, system audio, network controllers (some
models), and SCSI controllers (some models).
Network Service
Boot Enables/disables the workstation’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.
*Option supported on select models.
