Intel IM-Q35 Series manual Peci

BIOS Setup

Hardware Prefetcher

Setting to [Enabled], the processor's hardware prefetcher will be enabled and allowed to automatically prefetch data and code for the processor.

Adjacent Cache Line Prefetch

Setting to [Enabled], the processor will retrieve the currently requested cache line, as well as the subsequent cache line.

Max CPUID Value Limit

This item allows you to circumvent problems with older operating systems that do not support the Intel Pentium 4 processor with Hyper-Threading Technology. Setting to [Enabled], the processor will limit the maximum CPUID input value to 03h when queried, even if the processor supports a higher CPUID input value.

Execute-Disable Bit Capability

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.

Core Multi-Processing

Enable this feature, if your processor supports multi-core.

PECI

Platform Environment Control Interface (PECI) is able to provide digital data concerning processor temperature information.
