(Refer to Intel and Microsoft websites for more information.)
VMX
Select Enable for CPU-related Virtualization support. This feature is used in conjunc-
tion with the items: "Clear MCA," "Enable SMX," and "Lock Chipset" for Virtualization
media support. The options are
Enable and Disable.
Enable SMX
Select Enable for Safer Mode Extensions (SMX) support to enhance data security
in the processor. This feature is used in conjunction with the items: "Clear MCA,"
"VMX," and "Lock Chipset" for Virtualization media support. The options are En-
able and
Disable .
Lock Chipset
Select Enable to lock chipset register tables and set the register tables to "read-only"
to prevent new data being written into the processor to ensure system security. This
feature is used in conjunction with the items: "Clear MCA," "VMX," and "Enable
SMX" for Virtualization media support. The options are
Enable and
Disable.

.
Hardware Prefetcher (Available when supported by the CPU)
If set to Enable, the hardware prefetcher will prefetch streams of data and instruc-
tions from the main memory to the L2 cache to improve CPU performance. The
options are Disable and
Enable .
Adjacent Cache Line Prefetch (Available when supported by the CPU)

Clear MCA (Available if supported by the OS & the CPU)
Select Yes to enable Machine-Check Architecture (MCA) support for CPU error
logging. This feature is used in conjunction with the items below: "Execute Disable
Bit," "VMS," "Enable SMX," and "Lock Chipset" for Virtualization media support.
The default setting is
No.
Execute-Disable Bit (Available if supported by the OS & the CPU)
Select Enable for Execute Disable Bit Technology support, which will allow the
processor 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 flooding illegal
codes to overwhelm the processor or damage the system during an attack. This
feature is used in conjunction with the items: "Clear MCA," "VMX," "Enable SMX,"
