For each device, Device Available is the default setting and allows the operating system to access
the device. Device Hidden makes the device unavailable; it is disabled by the BIOS and cannot be
enabled by the operating system. When enabled, Embedded Security Device offers these options:
●
Embedded Security Device Support
● Enable/Disable—Turns the Trusted Platform Mechanism (TPM) on and off. If this option is
enabled, the following options become available:
◦ Power-On Authentication Support—Enables and disables an authentication feature that
requires you to enter a TPM user key password to boot the system. This feature uses
the TPM to generate and store the authentication password.
◦
Reset Authentication Credential—Resets the authentication functionality and clears all
authentication credentials.
NOTE: A setup password must be set to enable the Embedded Security Device and to access
any security features associated with the Embedded Security Device.
Network Service Enables or disables the ability to boot to the network using the
Boot
System IDs Asset Tag—A 16–byte string identifying the system.
Ownership Tag—An 80–byte string identifying ownership of the system. This tag is displayed on
the screen during POST.
Universal Unique Identifier (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—Enables you to set the keyboard locale for System ID entry.
DriveLock Allows you to select a hard drive, enable or disable DriveLock security on that drive, and set a
Security DriveLock password. This option appears only if your drive supports DriveLock.
CAUTION:
password is lost or forgotten. No method exists to recover the password or access the data.
System Security Data Execution Prevention—Enables or disables Data Execution Prevention mode in the
processors. This mode prohibits code from running in pages that were set up as data pages, and
prevents attacks such as buffer overflows. Operating system support is required for this feature.
Virtualization Technology (VTx)—Enables Intel Virtualization Technology to increase workstation
performance.
Description
Enabling DriveLock can render a hard drive permanently inaccessible if the master
F12 key or the boot order.
