MI BIOS
Setup

Hyper-threading
This item allows you to enable or disable Intel hyper-threading technology.

Active Processor Core
Use this to select how many processor cores you want to activate when you are
using a dual or quad core processor.

Limit CPUID Maximum
Setting this item to [Enable] allows legacy operating systems to boot even with-
out support for CPUs with extended CPUID functions.

Execute Disable Bit
This item specifies the Execute Disable Bit Feature. The settings are Enabled
and Disabled. The Optimal and Fail-Safe default setting is Enabled. If Disabled
is selected, the BIOS forces the XD feature flag to always return to 0.

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. It does this by creating virtual machines, each running its own x86
operating system.

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.
