Chapter 7: BIOS

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.

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 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 extended memory area above 1MB. 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.

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.
