On-Chip Video Window Size
This option enabled/disabled the on-chip video windows size for VGA driver use. The
settings are: enabled, Disabled.
AGP Graphics Aperture Size
This option determines the effective size of the graphics aperture used in the particular PAC
configuration. The AGP aperture is memory-mapped, while graphics data structure can
reside in a graphics aperture. The aperture range should be programmed as not cacheable
in the processor cache, accesses with the aperture range are forwarded to the main memory,
then PAC will translate the original issued address via a translation table that is maintained
on the main memory. The option allows the selection of an aperture size of 32MB, 64MB.

SDRAM CAS Latency Time
When synchronous DRAM is installed, the number of clock cycles of CAS latency depends
on the DRAM timing. The settings are: 2 and 3.
SDRAM Cycle Time Tras/Trc
Select the number of SCLKs for an access cycle. The settings are: 5/7 and 6/8.

When set to "Auto",
BIOS will program this
Timing mainly by the
SPD method. SPD means
"Serial Presence
