<dl>
 <dt><b>Hardware Prefetch:</b></dt> 
 <dd>
  This BIOS option allows the enabling/disabling of a processor mechanism 
  to prefetch data into the cache according to a pattern-recognition algorithm
  In some cases, setting this option to Disabled may improve performance. 
  Users should only disable this option after performing application benchmarking 
  to verify improved performance in their environment.
 </dd>

 <dt><b>Adjacent Sector Prefetch:</b></dt> 
 <dd>
  This BIOS option allows the enabling/disabling of a processor mechanism 
  to fetch the adjacent cache line within a 128-byte sector that contains the 
  data needed due to a cache line miss.
  In some cases, setting this option to Disabled may improve performance. 
  Users should only disable this option after performing application benchmarking 
  to verify improved performance in their environment.
 </dd>

 <dt><b>High Bandwidth:</b></dt> 
 <dd>Enabling this option allows the chipset to defer memory transactions and 
     process them out of order for optimal performance.</dd>

 <dt><b>Power C-States:</b></dt> 
 <dd>Enabling the CPU States causes the CPU to enter a low-power mode when the CPU is idle.</dd>

 <dt><b>Turbo Boost:</b></dt> 
 <dd> 
	This BIOS option can be set to Power Optimized or Traditional. When Power 
	Optimized is selected, Intel Turbo Boost Technology engages after Performance state 
	P0 is sustained for longer than two seconds. When Traditional is selected, Intel 
	Turbo Boost Technology is engaged even for P0 requests less than two seconds.
 </dd> 

 <dt><b>Demand Scrub:</b></dt> 
 <dd> 
  Demand scrub occurs when the memory controller reads memory for data or 
  instructions and the demand scrubbing logic detects a correctable error. Correct 
  data is forwarded to the memory controller and written to memory. With demand 
  scrubbing disabled, the data being read into the memory controller will be corrected 
  by the ECC logic but no write to main memory occurs. Since the data is not corrected 
  in memory, subsequent reads to the same will need to be corrected.
