with extended CPUID functions. The options are Enabled and Disabled (for the

Windows OS).

Execute-Disable Bit Capability (Available if supported by the OS & the

CPU)

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.)

accessing and processing in the DCU to enhance CPU performance. The options

are Disabled and Enabled.

DCU IP Prefetcher

Select Enabled for DCU (Data Cache Unit) IP Prefetcher support, which will

prefetch IP addresses to improve network connectivity and system performance.

The options are Enabled and Disabled.

Intel® Virtualization Technology (Available when supported by the CPU)
