or to be written into L1, L2 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. Se-
lect 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 for fast CPU data process-
ing and operation. The options are Uncached, Write Through, Write Protect, and
Write Back.
Cache Base 512K-640K
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 Static DROM (SDROM) or
written into L1, L2, 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 for fast CPU data processing and opera-
tion. The options are Uncached, Write Through, Write Protect, and Write Back.
Cache Extended Memory
If enabled, this feature will allow the data stored in the extended memory area
(above 1MB) to be cached (written) into a buffer, a storage area in Static DROM
(SDROM) or written into L1, L2 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 system memory area above
1MB. Select Write Back to allow the CPU to write data back directly from the buffer
without writing data to the System Memory for fast CPU data processing and opera-
tion. The options are Uncached, Write Through, Write Protect, and Write Back.
Discrete MTRR Allocation
If enabled, MTRRs (-Memory Type Range Registers) are confi gured as distinct,
separate units and cannot be overlapped. Set to Enabled to enhance graphic perfor-
mance when using a Linux graphic driver that requires write-combining confi guration
with 4GB or more memory. The options are Enabled and Disabled.
Reset Confi guration Data
If set to Yes, this setting clears the Extended System Confi guration Data- (ESCD)
area. The options are Yes and No.
