This is a read-only item, which displays whether the ratio status of this

motherboard is “Locked” or “Unlocked”. If it shows “Unlocked”, you will find

an item Ratio CMOS Setting appears to allow you changing the ratio value

of this motherboard. If it shows “Locked”, then the item Ratio CMOS Set-

ting will be hidden. If you use the ratio value to time the CPU frequency, it will

be equal to the core speed of the installed processor.

This is a read-only item, which displays the ratio actual value of this

motherboard.

You may select [Enabled] to enable P4 CPU internal thermal control mecha-

nism to keep the CPU from overheated.

To enable this feature, it requires a computer system with an Intel Pentium

®

4

processor that supports Hyper-Threading technology and an operating sys-

tem that includes optimization for this technology, such as Microsoft

®

 Win-

dows

® 

XP. Set to [Auto] if using Microsoft

®

 Windows

®

 XP, or Linux kernel

version 2.4.18 or higher. This option will be hidden if the installed CPU does

not support Hyper-Threading technology.

For Prescott CPU only, some OSes (ex. NT4.0) cannot handle the function

with disable. This should be enabled in order to boot legacy OSes that

cannot support CPUs with extended CPUID functions.

       No-Execution (NX) Memory Protection Technology is an enhancement to the

       IA-32 Intel Architecture. An IA-32 processor with “No Execute (NX) Memory

      Protection” can prevent data pages from being used by malicious software

      to execute code.  This option will be hidden if the current CPU does not

      support No-Excute Memory Protection.

      All processors support the Halt State (C1). The C1 state is supported

      through the native processor instructions HLT and MWAIT and requires no

      hardware support from the chipset. In the C1 power state, the processor

      maintains the context of the system caches.

       Intel (R) SpeedStep(tm) tech. is Intel’s new power saving technology. Proces-

     sor can switch between multiple frequency and voltage points to enable

      power savings. If you select [Enabled], you need to set the “Power Schemes”

     as “Portable/Laptop” to enable this function.
