AGP Aperture Size
This field selects the size of the Accelerated Graphics Port (AGP) aperture. The aperture is a
portion of the PCI memory address range dedicated for graphics memory address space.
Host cycles that hit the aperture range are forwarded to the AGP without any translation.
The default is 64MB. You may increase this memory when you need to have faster access
for 3D graphics applications (e.g. games).
AGP Mode
This item allows you to select 1x, 2x or 4x AGP mode.
AGP Driving Control
The recommended setting for this field is the default “Auto”. If you have an unstable AGP
card you may use this field to choose the appropriate settings. If you do need to tune the
timing, please consult your AGP Card manual or Vendor.
AGP Driving Value
This item allows you to adjust the AGP driving force.
AGP Fast Write
Some AGP cards, like G-Force, support AGP fast write. If you have an AGP card that sup-
ports this mode you can enable this field. If your AGP card does not support the fast write
mode then leave this field “disabled”.
AGP Master 1 WS Write
When Enabled, writes to the AGP are executed with one-wait states.
AGP Master 1 WS Read
When Enabled, reads to the AGP are executed with one-wait states.
3.5.3. CPU & PCI Bus Control

CPU & PCI Bus Control
CPU to PCI Write Buffer
When you enable this option writes from the CPU to the PCI bus are buffered so that the
CPU will not have to wait until the write is completed before starting another write cycle.
PCI Master 0 WS Write
When enabled, writes to the PCI bus are executed with zero wait states.
