Description
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 you can force a network boot by pressing F12 during POST.
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.
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.
Runtime Power Management
Enables Enhanced Intel SpeedStep Technology (EIST) and Demand-Based Switching (DBS). This
option allows the operating system to tune processor performance states depending on load.
Idle Power Savings
When set to Enhanced, this option enables C1E, the high-efficiency processor halt state. When
the operating system puts a processor in idle mode, its power consumption is reduced. This option
reduces power consumption when the load is light. Operating system support is required for this
feature.
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 IDE and SATA drives when
resuming from S3, before returning to the operating system.
ACPI S3 PS2 Mouse Wake Up
