BIOS Utility 2-35
Cache Scheme
This parameter sets the cache to
Write-through
or
Write-back
modes.
Write-back
updates the cache but not the memory when
there is a write instruction. It updates the memory only when there is
an inconsistency between the cache and the memory.
Write-through
updates both the cache and the memory whenever
there is a write instruction.
Memory at 15MB-16MB Reserved For
To prevent memory address conflicts between the system and
expansion boards, reserve this memory range for the use of either the
system or an expansion board.
Some VGA cards have required settings for
this feature. Check your VGA card manual
before setting this parameter.
