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 Mode] even if you are using an AGP 1x video card. When set
to [1X Mode], the 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

(uncacheable) if your display card does not support this feature, otherwise
the system may not boot. Configuration options: [UC] [USWC]
Delay Transaction [Disabled]
When set to [Enabled], this feature frees the PCI bus when the CPU is

PCI clocks without PCI delayed transaction. Set this field to [Disabled]
when using ISA cards that are not PCI 2.1 compliant. Configuration
options: [Enabled] [Disabled]

secondary IDE channel, or both. You can also set both channels to
