performance. This field applies only when synchronous DRAM is installed in the system.
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 :
Selecting “Enabled allows caching of the video BIOS ROM at
C0000h – C7FFFh, resulting in better video performance. However, if any program writes
to this memory area, a memory error may result.
Memory Hole At 15M-16M :
The default setting is “Disabled”. Set to “Enable” when the
system memory size is equal to or greater than 16M bytes, then the physical memory
address from 15M to 16M will be passed to PCI or ISA. Thus, there will be a 1M Bytes
hole in your system memory. This option is designed for some OS with special add-on
cards which need 15M-16M memory space.
CPU Latency Timer:
Select “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. Select “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 default setting is Enabled.
AGP Graphics Aperture Size:
The field sets aperture size of the graphics. The aperture
is a portion of the PCI memory address range dedicated for graphics memory address
space. Host cycles that hit the aperture range are forwarded to the AGP without any
translation. The options available are 4M, 8M, 16M, 32M, 64M, 128M and 256M. The
default setting is 64M.
