<i>This BIOS feature allows you to select the size of the AGP aperture. The aperture is a portion of the PCI memory address range that is to be dedicated for use as AGP memory address space. Host cycles that hit the aperture range are forwarded to the AGP bus without need for translation. The aperture size also determines the maximum amount of system RAM that can be allocated to the AGP graphics card for texture storage.</i>
