AGP & P2P Bridge Control
Press <Enter> and the following sub-menu appears:
AGP Aperture Size
This setting controls just how much system RAM can be allocated to
AGP for video purposes. The aperture is a portion of the PCI memory
address range dedicated to graphics memory address space. Host cycles
that hit the aperture range are forwarded to the AGP without any translation.
The option allows the selection of an aperture size of 32MB, 64MB, 128MB
and 256MB.
AGP Mode
This item sets an appropriate mode for the installed AGP card. Setting
options: 1X, 2X, 4X, 8X. Select 8X only if your AGP card supports it.
AGP Driving Control
This item is used to adjust the AGP driving force. Selecting Manual
allows you to select an AGP driving force in AGP Driving Value. It is
strongly recommended to select Auto to avoid any system error caused.
AGP Driving Value
This item specifies an AGP driving force.
AGP Fast Write
This option enables or disables the AGP Fast Write feature. The Fast
Write technology allows the CPU to write directly to the graphics card
without passing anything through the system memory and improves the
AGP 4X speed.
DBI Output for AGP Trans.
DBI means Dynamic Bus Inversion and this item is used in AGP 8x mode
only. Driven by the source to indicate whether the corresponding data bit
group needs to be inverted on the receiving end. Used to limit the number
of simultaneously switching outputs to 8 for each 16-pin group. It is not
available if your AGP card is not 8x-supported.
