AGP Aperture Size : (
default setting: 64MB )
There is the AGP slot on the board and which allows user to install the AGP display
card in the system. The AGP display card will use some of the system memory to store
3D texture mapping data so that the video performance can be increased tremendously.
You may use this field to define the memory size which you prefer to use with the
AGP card. The memory size selectable in this field can be 4MB to 256MB.
It seems that the default setting –64MB is huge. In fact, what is defined in the BIOS
selection is to tell the operation system the maximum memory can be shared by AGP
card to store the 3D texture mapping data. So you need not to worry that your system
memory will be insufficient. The larger aperture size will let you have the better
performance on 3D Video display.
There is the VGART.VXD utility comes with the AGP card and it will decide the actual
memory size which will be shared by AGP card. If you are installing the Windows 98
operating system, the feature are already supported by the OS and you can select the
memory for the AGP Aperture size.

( Default setting: Enabled )

then onle 1X AGP card will be supported by this mainboard.
