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 into which BIOS can write (cache) data. Select Write
Protect to enable this function, and this area will be reserved for BIOS ROM ac-
cess 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 into which BIOS can write (cache) data. 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 block 0-512K
to be cached (written) into a buffer, a storage area in the Static DROM (SDROM)
or to be written into the 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 opera-
tion. 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 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 pro-
cessing and operation. The options are Uncached, Write Through, Write Protect
and Write Back.
