Ordering if 2000 or an earlier version is used. The options are Modern Ordering
and Legacy Ordering.
Max CPUID Value Limit
This feature allows the user to set the maximum CPU ID value. Enable this feature
to boot the legacy operating systems that cannot support processors with extended
CPUID functions. The options are Enabled and Disabled (for the Windows OS).
Intel® Virtualization Technology (Available when supported by the CPU)
Select Enabled to enable Virtualization Technology support which will allow one
platform to run multiple operating systems and applications in independent parti-
tions, creating multiple "virtual" systems in one physical computer. The options are
Enabled and Disabled. Note: If there is any change to this setting, you will need
to power off and restart the system for the change to take effect. Please refer to
Intel's web site for detailed information.
Execute-Disable Bit Capability (Available when supported by the OS and
the CPU)
Set to Enabled to enable the Execute Disable Bit support which will allow the proces-
sor to designate areas in the system memory where an application code can execute
and where it cannot, thus preventing a worm or a virus from fl ooding illegal codes
to overwhelm the processor or damage the system during an attack. The default is
Enabled. (Refer to Intel and Microsoft Web Sites for more information.)
CPU Multi-Core Enable/Disable (Available when supported by the CPU)
Set to Enabled to enable multi-core CPU support to enhance CPU performance for
the following CPU Cores. The options are Disabled and Enabled.

A20M
When the A20M# pin is enabled, it will force address bit 20 to zero (to be masked)
to emulate real-address mode address wraparound at 1 MB. Set this item to En-
abled for the legacy operating systems and applications that require A20M support
to work properly. The options are Enabled and Disabled.
Intel® SpeedStep™ Technology
Intel EIST (Enhanced Intel SpeedStep Technology) allows the system to automati-
cally adjust the processor voltage and core frequency in an effort to reduce power
consumption and heat dissipation. Please refer to Intel's web site for detailed infor-
mation. The options are Disable (Disable GV3) and Enable (Enable GV3).
