2.4.2 CPU Configuration The items in this menu show the CPU-related information that the BIOS automatically detects. Ratio CMOS Setting [Auto] Sets the ratio between CPU core clock and the FSB frequency. Key in ratio numbers directly. If an invalid ratio is set in CMOS, then the actual and set values may differ. C1E Support [Enabled] Allows you to enable or disable the Enhanced Halt State function. Configuration options: [Disabled] [Enabled] Max CPUID Value Limit [Disabled] Setting this item to [Enabled] allows legacy operating systems to boot even without support for CPUs with extended CPUID functions. Configuration options: [Disabled] [Enabled] Intel(R) Virtualization Tech [Enabled] Enables or disables Intel® Virtualization Technology. Virtualization enhanced by Intel® Virtualization Technology allows a platform to run multiple operating systems and applications in independent partitions. With virtualization, one computer system can function as multiple virtual systems. Configuration options: [Enabled] [Disabled] CPU TM function [Enabled] Enables or disables Intel® CPU Thermal Monitor (TM) function, a CPU overheating protection function. When enabled, the CPU core frequency and voltage are reduced when the CPU overheats. Configuration options: [Disabled] [Enabled] Execute-Disable Bit Capability [Enabled] Allows you to enable or disable the No-Execution Page Protection Technology. Setting this item to [Disabled] forces the XD feature flag to always return to zero (0). Configuration options: [Disabled] [Enabled] The following item appears only when you installed an Intel® CPU that supports the Enhanced Intel® SpeedStep® Technology (EIST). Intel(R) SpeedStep(TM) Tech [Enabled] Allows you to use the Enhanced Intel® SpeedStep® Technology. When set to [Enabled], you can adjust the system power settings in the operating system to use the EIST feature. Set this item to [Disabled] if you do not want to use the EIST.
