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 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 to write (cache) its data into this
reserved memory area. Select Write Protect to enable this 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 DRM
(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 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.

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
