NOTE: All related settings of SDRAM are set to Auto. It means that all
parameters of SDRAM are decided by the SPD value of Memory.
BIOS will use the optimized settings to configure the SDRAM
that on your system.
System BIOS Cacheable
When this function is enabled, the BIOS ROM’s addresses at
F0000H-FFFFFH will be duplicated into the SRAM. It will work with the
cache controller that is enabled.
Enabled <Default> BIOS access cached
Disabled BIOS access not cached
Video BIOS Cacheable
As with caching the system BIOS above, enabling the Video BIOS cache
will cause access to video BIOS addressed at C0000H to C7FFFH to be
cached, it the cache controller is also enabled.
Enabled <Default> Video BIOS access cached
Disabled Video BIOS access not cached
Memory Hole at 15MB - 16MB
In order to improve performance, certain space in memory can be
reserved for ISA cards. This field allows you to reserve 15MB to 16MB
memory address space to ISA expansion cards. This makes memory
from 15MB and up unavailable to the system. Expansion cards can only
access memory up to 16MB. By default, this field is set to Disabled.
CPU Latency Timer
When Disabled, a “deferrable” CPU cycle will be deferred immediately
after the chipset receives another ADS#. The default is Disabled.
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
This field determines the effective size of the Graphic Aperture used for a
particular GMCH configuration. It can be updated by the GMCH-specific
BIOS configuration sequence before the PCI standard bus enumeration
sequence takes place. If it is not updated then a default value will select
