Execute Disable Bit Capability
This is an Intel hardware-based security feature that can help reduce system exposure to
viruses and malicious code. It allows the processor to classify areas in memory where
application code can or cannot execute. When a malicious worm attempts to insert code in
the buffer, the processor disables its code execution, preventing damage and worm
propagation. To use Execute Disable Bit you must have a PC or server with a processor with
Execute Disable Bit capability and a supporting operating system.
Limit CPUID Maximum
When the computer is boots, the operating system executes its CPUID instruction to identify
the processor and its capabilities. Before it can do so, it must first query the processor to
find out the highest input value the CPUID recognizes. This determines the kind of basic
information CPUID can provide the operating system. This option allows you to circumvent
problems with older operating systems.
When Enabled, the processor will limit the maximum CPUID input value to 03h when queried,
even if the processor supports a higher CPUID input value. When Disabled, the processor
will return the actual maximum CPUID input value of the processor when queried.
Intel® Virtualization Tech
Intel® Virtualization Technology is a set of platform features that supports virtualization of
platform hardware and multiple software environmentss. When enabled, it offers data center
managers the ability to consolidate multiple workloads on one physical server system.
Intel® C-STATE tech
This item allows you to Enable/Disable the C-STATE function. C-STATE make the power and
thermal control unit part of the core logic and not part of the chipset as before.
Enhanced C1~C4
Enable or Disable Enhanced C1~C4 state. Set this value to Enabled/Disabled.
