DRAM Timing Setting
Please refer to section 3-6-1
System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in
better system performance. However, if any program writes to this memory area, a system
error may result. The settings are: Enabled and Disabled.
Video BIOS Cacheable
Select Enabled allows caching of the video BIOS, resulting in better system performance.
However, if any program writes to this memory area, a system error may result. The settings
are: Enabled and Disabled.
CPU Latency Timer
During Enabled, A deferrable CPU cycle will only be Deferred after it has been in a Snoop
Stall for 31 clocks and another ADS# has arrived. During Disabled, A deferrable CPU cycle
will be Deferred immediately after the GMCH receives another ADS#.
Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles.
Select Enabled to support compliance with PCI specification version 2.1. The settings are:
Enabled and Disabled.
