Cache Base 0-512K
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, 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 base memory area of Block 0-512K.
Select "Write Back" to allow CPU to write data back directly from the buffer without
writing data to the System Memory for fast CPU data processing 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 CPU to write data back directly from the buffer without writing
data to the System Memory for fast CPU data processing and operation. 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 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 0-512K. Select
"Write Back" to allow CPU to write data back directly from the buffer without writing
data to the System Memory for fast CPU data processing and operation. The options
are Uncached, Write Through, Write Protect, and
Write Back
.
Discrete MTRR Allocation
If enabled, MTRRs (-Memory Type Range Registers) are configured as distinct,
separate units and cannot be overlapped. If enabled, the user can achieve better
graphic effects when using a Linux graphic driver that requires the write-combining
configuration with 4GB or more memory. The options are Enabled and
Disabled
.
