Execute Disable Bit When enabled, the processor prevents the execution of code in data-only memory pages. This provides some protection against buffer overflow attacks. When disabled, the processor will not restrict code execution in any memory area. This makes the processor more vulnerable to buffer overflow attacks. Options available: Enabled/Disabled. Default setting is Enabled. Energy Performance Energy Performance Bias is Intel CPU function. The larger value in MSR_ENERGY_PERFORMANCE_BIAS register, CPU will save more power but lose more performance. Note: This register will be changed by OS too if OS support it like Windows 2008 or newer Linux. Options available: Performance : Write value 0 into MSR_ENERGY_PERFORMANCE_BIAS Balanced Performance: Write value 7 into MSR_ENERGY_PERFORMANCE_BIAS Balanced Energy: Write value 11 into MSR_ENERGY_PERFORMANCE_BIAS Energy Efficient: Write value 15 into MSR_ENERGY_PERFORMANCE_BIAS Default setting is Balanced Performance. Intel Virtualization Technology Select whether to enable the Intel Virtualization Technology function. VT allows a single platform to run multiple operating systems in independent partitions. Options available: Enabled/Disabled. Default setting is Enabled. BIOS Setup - 42 -

Execute Disable Bit
When enabled, the processor prevents the execution of code in data-only memory pages. This provides
some protection against buffer overflow attacks.
When disabled, the processor will not restrict code execution in any memory area. This makes the
processor more vulnerable to buffer overflow attacks.
Options available: Enabled/Disabled. Default setting is
Enabled
.
Energy Performance
Energy Performance Bias is Intel CPU function.
The larger value in MSR_ENERGY_PERFORMANCE_BIAS register,
CPU will save more power but lose more performance.
Note:
This register will be changed by OS too if OS support it like Windows 2008 or newer Linux.
Options available:
Performance : Write value 0 into MSR_ENERGY_PERFORMANCE_BIAS
Balanced Performance: Write value 7 into MSR_ENERGY_PERFORMANCE_BIAS
Balanced Energy: Write value 11 into MSR_ENERGY_PERFORMANCE_BIAS
Energy Efficient: Write value 15 into MSR_ENERGY_PERFORMANCE_BIAS
Default setting is
Balanced Performance
.
Intel Virtualization Technology
Select whether to enable the Intel Virtualization Technology function. VT allows a single platform to run
multiple operating systems in independent partitions.
Options available: Enabled/Disabled. Default setting is
Enabled
