AGP Aperture Size 

This setting controls how much memory space can be allocated to AGP 
for video purposes.  The aperture is a portion of the PCI memory 
address range dedicated to graphics memory address space.  Host 
cycles that hit the aperture range are forwarded to the AGP without any 
translation.
