2.3.1 Internal Cache (CPU Cache)
This parameter enables or disables the internal cache memory.
2.3.2 External Cache
This parameter enables or disables the external cache memory.
Cache Scheme
This parameter fixes the cache setting to Write-back mode. Write-
back updates the cache but not the memory when there is a write
instruction. It updates the memory only when these is an
inconsistency between the cache and the memory.
2.3.3 ECC/Parity Mode Selection
This parameter allows you to enable or disable the ECC and parity
check feature.
The ECC option, ECC detects of both single-bit and multiple-bit errors
but corrects only single-bit errors. The Parity option allows parity
check. If it detects any parity errors, it signals the operating system of
the parity error detection.
Disable this parameter if you installed SIMMs without parity.
2.3.4 Memory at 15MB-16MB
To prevent memory address conflicts between the system and
expansion boards, reserve this memory range for the use of either the
system or an expansion board. Before setting this parameter, check
your add-on card manual to determine if your add-on card needs this
memory space. If not, set this parameter to System Use.
