3.2.2.2 CPU Configuration
 Hardware Prefetcher
Hardware Prefetcher is a technique that fetches instructions and/or data from
memory into the CPU cache memory well before the CPU needs it to improve
the load-to-use latency. You may choose to Enable or Disable it.
 Adjacent Cache Line Prefetch
The Adjacent Cache-Line Prefetch mechanism, like automatic hardware
prefetch, operates without programmer intervention. When it is enabled through
the BIOS, two 64-byte cache lines are fetched into a 128-byte sector, regardless
of whether the additional cache line has been requested or not. You may choose
to Enable or Disable it.
 Intel Virtualization Technology
This feature is used to Enable or Disable Intel Virtualization Technology (IVT)
extension. It allows multiple operating systems to run simultaneously on the
same system by creating virtual machines, each running its own x86 operating
system.
 Active Processor Core
Use this item to select the number of processor cores you want to activate when
you are using a dual or quad core processor.
 AES
Enable or Disable CPA advanced encryption standard instruction.
 Intel Trusted Execution Technology
"Enable or Disable" utilization of additional hardware capabilities provided by
Intel Trusted Execution Technology. Changes require a full power cycle to take
effect.
 Rest AUX Content
Reset TPM AUX content. TXT may not be functional after AUX content gets
reset.
