BIOS Setup
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.
Enables C1E function to reduce the CPU frequency and voltage for
power-saving in halt state.
Disables this function.
Locks the CFG lock bit.
Un-locks the CFG lock bit.
