Heading Option Description
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 Boot
Enables a Network Service Boot, which boots using the NIC PXE option ROM. In this case, the
actual boot image resides on a remote server. When enabled, you can set the boot order of the
NIC PXE option ROM and force a network boot by pressing F12 during POST.
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.
UUID (Universal Unique Identifier)
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.
OS Security Data Execution Prevention
Enables/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.
Intel Virtualization Technology
Enables Intel Virtualization Technology to increase workstation performance.
OS Management of Embedded Security Device
Enables/disables the ability of the operating system to control the TPM device. This includes turning
it on/off, initializing it, and resetting it.
Reset of Embedded Security Device through OS
Enables/disables the ability of the operating system to reset the TPM.
Power OS Power
Management
Runtime Power Management
Enables Enhanced Intel SpeedStep Technology (EIST) and Demand-Based Switching (DBS). This
allows the operating system to tune processor performance states depending on load.
Idle Power Savings
When set to Enhanced, this enables C1E, the high-efficiency processor halt state. When the
operating system puts a processor in idle mode, this reduces its power consumption
ACPI S3 Support
Enables the suspend-to-RAM state. This option is mostly for troubleshooting purposes; the
operating system will never enter S3 if one of its drivers does not support that state. Enabled by
default; disabled for troubleshooting.
ACPI S3 Hard Disk Reset
When enabled, the BIOS sends a “drive reset” command to the SAS and SATA drives when
resuming from S3, before returning to the operating system.
ACPI S3 PS2 Mouse Wake Up
