EIST (Intel (R) SpeedStep(tm) tech.), and you plan to adjust the ratio value, please disable the option " Intel (R) SpeedStep(tm) tech." in advance. Enhance Halt State 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) Virtualization tech. When this option is set to [Enabled], a VMM (Virtual Machine Architecture) can utilize the additional hardware capabilities provided by Vanderpool Technology. This option will be hidden if the installed CPU does not support Intel (R) Virtualization Technology. CPU Thermal Throttling You may select [Enabled] to enable P4 CPU internal thermal control mechanism to keep the CPU from overheated. This option will be hidden if the current CPU does not support CPU Thermal Throttling. No-Excute Memory Protection 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. Hyper Threading Technology To enable this feature, it requires a computer system with an Intel Pentium® 4 processor that supports Hyper-Threading technology and an operating system that includes optimization for this technology, such as Microsoft® Windows® XP / VistaTM / 7. Set to [Enabled] if using Microsoft® Windows® XP, VistaTM, 7 or Linux kernel version 2.4.18 or higher. This option will be hidden if the installed CPU does not support Hyper-Threading technology. Intel (R) SpeedStep(tm) tech. Intel (R) SpeedStep(tm) tech. is Intel's new power saving technology. Processor can switch between multiple frequency and voltage points to enable power savings. The default value is [Auto]. Configuration options: [Auto], [Enabled] and [Disabled]. If you install Windows® XP and select [Auto], you need to set the "Power Schemes" as "Portable/Laptop" to enable this function. If you install Windows® 7 / VistaTM and want to enable this function, please set this item to [Enabled]. This item will be hidden if the current CPU does not support Intel (R) SpeedStep(tm) tech.. Please note that enabling this function may reduce CPU voltage and lead to system stability or compatibility issue with some power supplies. Please set this item to [Disable] if above issue occurs. 37

please disable the option “ Intel (R) SpeedStep(tm) tech.” in advance.
Enhance Halt State
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) Virtualization tech.
When this option is set to [Enabled], a VMM (Virtual Machine Architecture)
can utilize the additional hardware capabilities provided by Vanderpool
Technology. This option will be hidden if the installed CPU does not support
Intel (R) Virtualization Technology.
CPU Thermal Throttling
You may select [Enabled] to enable P4 CPU internal thermal control mecha-
nism to keep the CPU from overheated. This option will be hidden if the
current CPU does not support CPU Thermal Throttling.
No-Excute Memory Protection
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.
Hyper Threading Technology
To enable this feature, it requires a computer system with an Intel Pentium
