AGP Aperture Size
This item defines the size of the aperture if you use an AGP graphics adapter. The AGP aperture refers to a section of
the PCI memory address range used for graphics memory. We recommend that you leave this item at the default value.
The default value is 64M.
AGP Driving Control
This item is used to signal driving current on AGP cards to auto or manual. Some AGP cards need stronger than nor-
mal driving current in order to operate. We recommend that leave this item at the default. The default value is Auto.
AGP Driving Value
When AGP Driving Control is set to Manual, use this item to set the AGP current driving value. The default value is
DA.
AGP Fast Write
This item lets you enable or disable the caching of display data for the video memory of the processor. Enabling this item can
greatly improve the display speed. Disable this item if your graphics display card does not support this feature. The
default value is Disabled.
AGP Master 1 WS Write
This implements a single delay when writing to the AGP Bus. By default, two-wait states are used by the system, pro-
viding greater stability. The default value is Disabled.
AGP Master 1 WS Read
This implements a single delay when reading to the AGP Bus. By default, two-wait states are used by the system,
allowing for greater stability. The default value is Disabled.
