Intel Virtualisation Technology
Used to support the visualisation of platform hardware and multiple software
environments. Based on Virtual Machine Extensions (VMX), to support the
application of multiple software environments by using virtual computers. The
virtualisation technology enhances the processor support for virtualisation purposes
on the over 16-bit and 32-bit protected modes and on the Intel® Extended Memory
64 Technology (EM64T) mode.

VT-d
VT-d (Intel Virtualization Technology for Directed I/O) is a hardware support for the
common use of I/O devices by several virtual machines. VMM systems (Virtual
Machine Monitor) can use VT-d to manage various virtual machines which access
the same physical I/O device.

Power Technology
Configures the CPU power management functions
1. Disabled
–
the CPU power management functions are disabled
2. Energy Efficient
–
the CPU power management functions are optimised for
energy efficiency
3. Custom

Enhanced SpeedStep
Specifies the voltage and frequency of the processor. EIST (Enhanced Intel
SpeedStep® Technology) is an energy-saving function.
o
The processor voltage is adapted to the particular system requirements which
are needed at any one time. A reduction in the clock frequency causes the
system to require less energy.
