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 to write (cache) its data into this
reserved memory area. Select Write Protect to enable the function and reserve
this area for the Video 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 to write (cache) its data into this
reserved memory area. Select Write Protect to enable the function and reserve
this area for the 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 allows 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 al-
low 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 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 allows 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 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.
Cache Extended Memory
