AGP Capability [4X Mode]
This motherboard supports the AGP 4x interface that transfers video data at
1066MB/s. AGP 4X is backward-compatible, so you may keep the default [4X

AGP interface only provides a peak data throughput of 266MB/s even if you are
using an AGP 4X card. Configuration options: [1X Mode] [4X Mode]
Video Memory Cache Mode [UC]
USWC (uncacheable, speculative write combining) is a new cache technology for
the video memory of the processor. It can greatly improve the display speed by

card does not support this feature, otherwise the system may not boot.
Configuration options: [UC] [USWC]

When set to [Enabled], this feature frees the PCI bus when the CPU is accessing

PCI delayed transaction. Set this field to [Disabled] when using ISA cards that are
not PCI 2.1 compliant. Configuration options: [Enabled] [Disabled]

This field allows you to enable either the primary IDE channel or secondary IDE
channel, or both. You can also set both channels to [Disabled].
