Memory Cache
Cache System BIOS Area
This setting allows you to designate a reserve area in the system memory to be
used as a System BIOS buffer to allow the BIOS write (cache) its data into this
reserved memory area. Select "Write Protect" to enable this function, and this
area will be reserved for BIOS ROM access only. Select "Uncached" to disable this
function and make this area available for other devices.
Cache Video BIOS Area
This setting allows you to designate a reserve area in the system memory to be
used as a Video BIOS buffer to allow the BIOS write (cache) its data into this
reserved memory area. Select "Write Protect" to enable the function and this area
will be reserved for Video BIOS ROM access only. Select "Uncached" to disable
this function and make this area available for other devices.
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 CPU's L1/L2 cache 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 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 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 the CPU's L1, L2, L3 cache 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.
