AGP Aperture Size

This option determines the effective size of the graphics aperture
used in the particular MCM configuration. The AGP aperture is memory -
mapped, while graphics data structure can reside in a graphics aperture. The
aperture range should be programmed as not cacheable in the processor
cache,accesses with the aperture range are forwarded to the main memory,
then MCM will translate the original issued address via a translation table
that is maintained on the main memory. The option allows the selection of an
aperture size of 4MB, 8MB, 16MB, 32MB, 64MB, 128MB and 256MB.
