Advanced Chipset Features

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 for-
warded to the AGP without any translation. The option allows the selection of an
aperture size of [32MB], [64MB], [128MB], [256MB] and [512MB].
AGP 3.0 Speed / AGP 2.0 Speed
AGP 3.0 Speed or AGP 2.0 Speed appears depending on the AGP card installed on
the mainboard. This item sets an appropriate speed for the installed AGP card. Setting
options for AGP 2.0 Speed: [1x], [1x2x], [1x2x4x]. Setting options for AGP 3.0 Speed:
[4x], [4x8x].
AGP Fast Write
The item enables or disables the AGP Fast Write feature. The Fast Write technology
allows CPU to write directly into the graphics controller without passing anything
through system memory and improves 8x speed accordingly. Select [Auto] only
when your AGP card supports the feature. Options: [Disabled], [Auto].
System BIOS Cacheable
Selecting [Enabled] allows caching of the system BIOS ROM at F0000h-FFFFFh,
resulting in better system performance. However, if any program writes to this
memory area, a system error may result. Setting options: [Enabled], [Disabled].
