► C1E Support
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.
► Limit CPUID MaxVal
This item is used to enable or disable CPUID maximum value limit conguration. Set Limit
CPUID MaxVal to 3, it should be [Disabled] for WinXP.
► Virtualization Technology (Appears only when CPU supports)
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.
► 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
overow 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,
rewall, spyware removal, e-mail ltering 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.
