functions. The options are Enabled and Disabled (for the Windows OS.)
Execute Disable Bit (Available if supported by the OS & the CPU)
Set to Enabled to enable the Execute Disable Bit which will allow the processor to
designate areas in the system memory where an application code can execute and

Enabled. (Refer to Intel and Microsoft Web Sites for more information.)

Select Enabled to enable Intel Vanderpool Technology support which will allow

being cached. The options are Disabled and Enabled.
