Table 7-3 Computer Setup—Security (continued)
●
Cover Removal Sensor - allows you to set the sensor to Disable/Notify User/Setup
Password.
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 computer if
the sensor detects that the cover has been removed.
Device Security Allows you to set Device Available/Device Hidden (default is Device Available) for:
●
Embedded security device
●
System audio
●
Network controller
●
Serial port (if applicable)
●
Parallel port (if applicable)
●
SATA ports (varies by model)
USB Security Allows you to set Enabled/Disabled (default is Enabled) for:
●
Front USB Ports
●
Rear USB Ports
●
Accessory USB Ports
Slot Security Allows you to disable any PCI or PCI Express slot. Default is enabled.
Network 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 be either a PCI
expansion card or embedded on the system board.) Default is enabled.
System IDs 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.
●
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.)
●
Chassis serial number. (These ID numbers are normally set in the factory and are used to
uniquely identify the system.)
●
Keyboard locale setting for System ID entry.
Master Boot Security
Record
Enables/disables Master Boot Record (MBR) security.
The MBR contains information needed to successfully boot from a disk and to access the data
stored on the disk. Master Boot Record Security may prevent unintentional or malicious changes
to the MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities.
It also allows you to recover the "last known good" MBR, should changes to the MBR be detected
when the system is restarted.
When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the
current bootable disk while in MS-DOS or Windows Safe Mode.
NOTE: Most operating systems control access to the MBR of the current bootable disk; the
BIOS cannot prevent changes that may occur while the operating system is running.
Restores the backup Master Boot Record to the current bootable disk. Default is disabled.
Only appears if all of the following conditions are true:
●
MBR security is enabled
