BIOS Setup

Allows you to determine whether to enable all CPU cores.

Options available: All/1/2/3. Default setting is

All

.

Limit CPUID Maximum

When enabled, the processor will limit the maximum COUID input values to 03h when queried, even if

the processor suppports a higher CPUID input value.

When disabled, the processor will return the actual maximum CPUID input value of the processor when

queried.

Options available: Enabled/Disabled. Default setting is

Disabled

.

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.


Enabled

.

Hardware Prefetcher

Select whether to enable the speculative prefetch unit of the processor.


Enabled

.

Adjacent Cache Line Prefetch

When enabled, cache lines are fetched in pairs. When disabled, only the required cache line is fetched.


Enabled

.

DCU Streamer Prefetch

Enable

prefetch of next L1 Data line based upon multiple loads in same cache line.


Enabled

.

DCU IP Prefetch

Enable

prefetch of next L1 Data line based upon sequential load history.


Enabled

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.
