MPS Table Version

This field allows you to select which MPS (Multi-Processor Specification) version to be used for the operating system. You need to select the MPS version supported by your operating system. To find out which version to use, consult the vendor of your operating system.

CPU Feature

Press <Enter> to enter the sub-menu and the following screen appears:

Hyper-Threading Technology

This field appears only when the CPU supports Hyper-Threading. The proces- sor uses Hyper-Threading technology to increase transaction rates and re- duces end-user response times. The technology treats the two cores inside the proces sor as two logic al proc ess ors that can exec ute ins tructions simultaneously. In this way, the system performance is highly improved. If you disable the function, the processor will use only one core to execute the instructions.

Execute Bit Support

Intel's Execute Disable Bit functionality can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. This functionality allows the processor to classify areas in memory by where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.

Set Limit CPUID MaxVal to 3

The Max CPUID Value Limit is designed to limit the listed speed of the processor to older operating systems.

Chipset Feature
