3 CAUTION ► Limit CPUID MaxVal This item is used to enable or disable CPUID maximum value limit configuration. Set Limit CPUID MaxVal to 3, it should be [Disabled] for WinXP. ► C1E Function C1E represents Enhanced HALT State. It is a feature which Intel CPU uses to reduce power consumption when in halt state. C1E drops the CPU's multiplier and voltage to lower levels when a HLT (halt) command is issued. This item is used to enable/disable the C1E support. ► Execute Disable Bit This item is used to enable/disable the Execute Disable Bit feature. Intel's Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow attacks when combined with a supporting operating system. Execute Disable Bit 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 and worm propagation. Replacing older computers with Execute Disable Bit-enabled systems can halt worm attacks, reducing the need for virus-related repairs. By combining Execute Disable Bit with anti-virus, firewall, spyware removal, e-mail filtering software, and other network security measures, IT managers can free IT resources for other initiatives. ► EIST Function You can enable/disable the EIST (Processor Power Management, PPM) through this item. ! Enhanced Intel SpeedStep® technology (EIST) allows the system to dynamically adjust processor voltage and core frequency, which can result in decreased average power consumption and decreased average heat production. There are some system requirements must be met, including CPU, chipset, motherboard, BIOS and operation system. Please refer to Intel Website for more information. ► Virtualization Technology (�A��p�p�e�a�r�s�o�n��ly��w�h�e�n��C��P�U��s�u�p�p�o�r�t�s�) Virtualization (i.e. Intel® Vanderpool Technology) allows a platform to run multiple operating systems and applications in independent partitions or "containers." One physical compute system can function as multiple "virtual" systems. Vanderpool Technology can help improve future virtualization solutions. This item will be displayed only when the CPU is supporting this feature and the setting is used to enable/disable it. 30

► Limit CPUID MaxVal
This item is used to enable or disable CPUID maximum value limit configuration. Set Limit
CPUID MaxVal to 3, it should be [Disabled] for WinXP.
► C1E Function
C1E represents Enhanced HALT State. It is a feature which Intel CPU uses to reduce power
consumption when in halt state. C1E drops the CPU's multiplier and voltage to lower levels
when a HLT (halt) command is issued. This item is used to enable/disable the C1E support.
► Execute Disable Bit
This item is used to enable/disable the Execute Disable Bit feature.
Intel's Execute Disable Bit functionality can help prevent certain classes of malicious buffer
overflow attacks when combined with a supporting operating system.
Execute Disable Bit 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 and worm propagation.
Replacing older computers with Execute Disable Bit-enabled systems can halt worm attacks,
reducing the need for virus-related repairs. By combining Execute Disable Bit with anti-virus,
firewall, spyware removal, e-mail filtering software, and other network security measures, IT
managers can free IT resources for other initiatives.
