If the installed processor supports the Intel
provides an option to enable or disable this feature. The default is enabled.
The BIOS creates additional entries in the ACPI MP tables to describe the virtual processors.
The SMBIOS Type 4 structure shows only the installed physical processors. It does not
describe the virtual processors.
Because some operating systems are not able to efficiently use the Intel
BIOS does not create entries in the Multi-Processor Specification, Version 1.4 tables to describe
the virtual processors.
3.2.4 Enhanced Intel SpeedStep
If the installed processor supports the Enhanced Intel SpeedStep
provides an option to enable or disable this feature. The Default is enabled.
3.2.5 Intel

Intel Turbo Boost Technology opportunistically and automatically allows the processor to run
faster than the marked frequency if the part is operating below power, temperature, and current
limits.
If the processor supports this feature, the BIOS setup provides an option to enable or disable
this feature. The default is enabled.

Execute Disable Bit Feature

The Execute Disable Bit feature (XD bit) can prevent data pages from being used by malicious
software to execute code. A processor with the XD bit feature can provide memory protection in
one of the following modes:
Legacy protected mode if Physical Address Extension (PAE) is enabled.
®
Intel 64 mode when 64-bit extension technology is enabled (Entering Intel
mode requires enabling PAE).
You can enable and disable the XD bit in the BIOS Setup. The default behavior is enabled.
Revision 1.2

Does not disable the processor.
–
Displays "8180: Processor 0x microcode update not found" message
–
