Performance/Watt
Select Power Optimized to use Intel Turbo Boost Technology to maximize system
performance (with maximum cooling) when performance state P0 lasts more than
two seconds. If Traditional is selected, Intel Turbo Boost Technology will be acti-
vated even when performance state P0 lasts less than two seconds. The options
are
Traditional and Power Optimized.
Execute Disable Bit (Available if supported by the OS & the CPU)
Set to Enabled for Execute Disable Bit support which will allow the processor to
designate areas in the system memory where an application code can execute and
where it cannot, thus preventing a worm or a virus from flooding illegal codes to over -
