The mainboard chipset provides two things in respect to the keyword AGP. - a high speed bus interface to the graphics controller - a memory paging uint exposed to the graphics controller and the CPU the 2nd is just a remapped view of the main memory, resembling some/any page of main memory in a new improved, linear order. aperture means nothing more than memory range. its a PCI config space based memory mapping to the physical bus address. your mainboard chipset should indicate that range on some of the first devices which typically either might be the host bridge/memory controller or the AGP bus bridge on the PCI bus config space. in theory you can call any PCI bus based mapped range an aperture. in practice the so called GART, AGP-GART or whatever this graphics aperture rante page translateion unit might be is the thing you do like.
