Heading Option Description
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
Sets 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 in the processors. Additional virtualization software (such
as VMware) is required to use virtualization. This feature requires a complete power down to be
activated. Operating system support is required for this feature.
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
Allows the PS/2 mouse to wake from ACPI S3. PS/2 keyboards are always enabled. (Disabling
this means that nudging the mouse will not trigger a system wake.)
USB Wake on Device Insertion
Enables the USB controllers to generate a wake event when a device is plugged in while the system
is in an ACPI sleep state. The matching USB controller must be set to wake the system (from
Windows, this is done from Device Manager, using the Power Management tab for that controller,
and setting the Allow this device to wake up the system check box).

SATA Power Management
Allows you to enable or disable SATA power management. This option still works when the
controller is in AHCI/RAID mode.
Thermal Fan Idle Mode
This setting changes the minimum fan speed. The fans are still automatically controlled.
