SYSTEM MANAGEMENT
Security Setup Password Allows you to set and enables setup (administrator) password.
NOTE: If the setup password is set, it is required to change Computer Setup options, flash the
ROM, and make changes to certain Plug ‘n Play settings under Windows.
Power-On Password Allows you to set and enable power-on password.
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.)
Password Options (This
selection will appear
only if a power-on
password is set.) Allows you to specify whether the password is required for warm boot ( CTRL+ALT+DEL ).
Hood sensor* Allows you to enable/disable solenoid hood (Smart Cover) lock.
NOTE: Notify User alerts the user that the sensor has detected that the cover has been
removed. Setup Password requires that the setup password be entered to boot the workstation
if the sensor detects that the cover has been removed.
This feature is supported on select models only.
DriveLock* Allows you to assign or modify a master or user password for certain hard drives. When
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.
Master Boot Record
Security* Allows you to enable or disable MBR Security.
When enabled, the BIOS rejects all requests to write to the MBR on the current bootable disk.
Each time the workstation is powered on or rebooted, the BIOS compares the MBR of the
bootable disk to the previously saved MBR. If changes are detected, you are given the option
of saving the MBR on the current bootable disk, restoring the previously saved MBR, or
disabling MBR security. You must know the setup password if one is set.
NOTE: Disable MBR Security before intentionally changing the formatting or partitioning of the
current bootable disk. Several disk utilities (such as FDISK and FORMAT) attempt to update
the MBR.
If MBR Security is enabled and disk accesses are being serviced by the BIOS, write requests
to the MBR are rejected, causing the utilities to report errors.
If MBR Security is enabled and disk accesses are being serviced by the operating system, any
MBR change will be detected by the BIOS during the next reboot, and an MBR Security
warning message will be displayed.
Save Master Boot
Record* Saves a backup copy of the Master Boot Record of the current bootable disk.
NOTE: Only appears if MBR Security is enabled.
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.
