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" the 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 operat-
ing 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.
