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, so that it can
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 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.

This feature is used to enable or disable the Intel Virtualization Technology (IVT)

same system. It does this by creating virtual machines, each running its own
x86 operating system.
