This setting enables you to designate a reserve area in the system memory to be used as a System
BIOS buffer to allow BIOS to write (cache) its data into it. Select Write Protect to enable the
function and reserve this area for system BIOS ROM access only. Select Uncached to disable this
function and make this area available for other devices.
If enabled, this feature will allow the data stored in the base memory area: block 0-512K to be
cached (written) into a buffer, a storage area in the Static DROM (SDROM), or to be written into
L1 or L2 cache inside the CPU to speed up CPU's operations. Select Uncached to disable this
function. Select Write Through to allow data to be cached into the buffer and written into the
system memory at the same time. Select Write Protect to prevent data from being written into the
base memory area of Block 0-512K. Select Write Back to allow the CPU to write data back
directly from the buffer without writing data to the system memory in order to speed up CPU's
operation. The options are Uncached, Write Through, Write Protect, and Write Back.
If enabled, this feature will allow the data stored in the memory area: 512K-640K to be cached
(written) into a buffer, a storage area in the SDRAM or written into L1, L2, or L3 cache inside the
CPU to speed up CPU operations. Select Uncached to disable this function. Select Write Through
to allow data to be cached into the buffer and written into the system memory at the same time.
Select Write Protect to prevent data from being written into the base memory area of Block
512-640K. Select Write Back to allow the CPU to write data back directly from the buffer without
writing data to the system memory to speed up CPU's operation. The options are Uncached, Write
Through, Write Protect, and Write Back.
If enabled, this feature will allow the data stored in the extended memory area to be cached
(written) into a buffer, a storage area in the Static DROM (SDROM), or written into L1, L2, or L3
cache inside the CPU to speed up CPU's operations. Select Uncached to disable this function.
Select Write Through to allow data to be cached into the buffer and written into the system
memory at the same time. Select Write Protect to prevent data from being written into the base
memory area of Block 0-512K. Select Write Back to allow the CPU to write data back directly
