Host Bus Fast Data Ready [Disabled]

Configuration options: [Disabled] [Enabled]

16-bit I/O Recovery Time [1 BUSCLK]

Configuration options: [4 BUSCLK] [1 BUSCLK] [2 BUSCLK] [3 BUSCLK]

8-bit I/O Recovery Time [1 BUSCLK]

Configuration options: [8 BUSCLK] [1 BUSCLK] [2 BUSCLK] [3 BUSCLK]
[4 BUSCLK] [5 BUSCLK] [6 BUSCLK] [7 BUSCLK]

Graphics Aperture Size [64MB]

This feature allows you to select the size of mapped memory for AGP graphic
data. Configuration options: [4MB] [8MB] [16MB] [32MB] [64MB]
[128MB] [256MB]

Video Memory Cache Mode [UC]

USWC (uncacheable, speculative write combining) is a new cache technol-
ogy for the video memory of the processor. It can greatly improve the dis-
play speed by caching the display data. You must set this to UC (uncacheable)
if your display card cannot support this feature; otherwise your system may
not boot. Configuration options: [UC] [USWC]

Data Integrity Mode [Non-ECC]

[Non-ECC] has byte-wise write capability but no provision for protecting
data integrity in the DRAM array. When [EC-Only] is selected, data errors
are detected but not corrected. [ECC] with hardware scrubbing allows the
detection of single-bit and multiple-bit errors and recovery of single-bit er-
rors. This field is available only if your DIMMs have ECC. Configuration
options: [Non-ECC] [EC-Only] [ECC]
