Video BIOS Shadow
-
This option controls the location of the contents of the 32KB of
Video ROM beginning at the C0000h memory location. The settings are:
Enabled
The contents of C0000h-C7FFFh are written to the same address in system
memory (RAM) for faster execution.
Disabled
The video ROM is not copied to RAM. The contents of the video ROM cannot be
read from or written to cache memory.
C8000-DFFFF Shadow -
These options control the location of the contents of the 16KB
expansion card ROMs beginning at the specified memory location. If no adapter ROM is
using the named ROM area, this area is made available to the local bus. Shadowing a ROM
reduces the memory available between 640KB and 1024KB by the amount used for this
purpose. The settings are
Enabled
or
Disabled
.

Auto Configuration -
When
Enabled
, pre-defined values for DRAM, Cache, Timings, etc.
are set according to the CPU type & system clock.
Enabled
is the recommended setting.
These settings are only editable when Auto Configuration is
Disabled
.
Note:
The first chipset settings deal with CPU access to dynamic random access memory
(DRAM). The default timings have been carefully chosen and should only be altered if data
is being lost. Such a scenario might occur if your system had mixed speed DRAM chips
