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
caching the display data. You must set this to UC (uncacheable) if your display
card does not support this feature, otherwise the system may not boot.
Configuration options: [UC] [USWC]

This field allows you to reserve an address space for ISA expansion cards. Setting

other system components. Expansion cards can only access memory up to 16MB.
Configuration options: [Disabled] [Enabled]
