Table 11 describes the bpp configuration mode values referenced in Table 10.  In Table 11, assume 
that for each configuration mode number, the features of all lower numbers are also supported.  
For example, if the supported configuration mode is 4, then modes 1 through 3 are also supported.  
DVD consists of both the overlay engine as well as the MPEG decoding; both are necessary for 
DVD playback.

DVMT enables enhanced graphics and memory performance through Direct AGP, and highly 
efficient memory utilization.  DVMT ensures the most efficient use of available system memory 
(up to 64 MB) for maximum 2-D/3-D graphics performance. 

DVMT uses a portion of system physical memory (as set in the BIOS Setup program) for 
compatibility with legacy applications.  An example of this would be when using VGA graphics 
under DOS.  Once loaded, the operating system and graphics drivers allocate the buffers needed 
for performing graphics functions.

The Intel Extreme Graphics Controller supports Zone Rendering Technology (ZRT).  ZRT is a 
process by which the screen is divided into several zones.  Each zone is completely cached and 
rendered on chip before being written to the frame buffer.  The benefits of ZRT include the 
following:

 

•  Increased memory efficiency via better localization of data 
•  Increased on-chip processing speed due to decreased wait time for data 
•  Increased effective pixel fill rates
