BIOS Setup
BIOS limits the maximum CPUID input value to circumvent boot
problems with older operating system that do not support the
processor with extended CPUID value.
Use the actual maximum CPUID input value.
Enables Intel Virtualization technology and allows a platform to run
multiple operating systems in independent partitions. The system
can function as multiple systems virtually.
Disables this function.
Allows the hardware prefetcher to automatically pre-fetch data
and instructions into L2 cache from memory for tuning the CPU
performance.
Disables the hardware prefetcher.
Enables adjacent cache line prefetching for reducing the cache
latency time and tuning the performance to the specific application.
Enables the requested cache line only.
Throttles down the CPU core clock speed when the CPU is over the
adaptive temperature.
Disables this function.
This setting will be configured automatically by BIOS.
Detects the idle state of system and reduce CPU power consumption
accordingly.
Disable this function.
