[Enabled]
BIOS will limit the maximum CPUID input value to circumvent
boot problems with older operating system that do not support the
processor with extended CPUID value.
[Disabled]
Use the actual maximum CPUID input value.
▶ Execute Disable Bit [Enabled]
Intel's Execute Disable Bit functionality can prevent certain classes of malicious "buf-
fer overflow" attacks where worms attempt to execute code to damage the system.
It is recommended that keeps this item enabled always.
[Enabled]
Enables NO-Execution protection to prevent the malicious attacks
and worms.
[Disabled]
Disables this function.
▶ Intel Virtualization Tech [Enabled]
Enables or disables Intel Virtualization technology.

and instructions into L2 cache from memory for tuning the CPU
performance.
[Disabled]
Disables the hardware prefetcher.
▶ Adjacent Cache Line Prefetch [Enabled]
Enables or disables the CPU hardware prefetcher (MLC Spatial prefetcher).
[Enabled]
