When enabled is selected, a subwindow similar to the one below is displayed to
select the cache write policy. The options for this setting are Write-back (default)
and Write-through for CPU cache.
Write policy
Write-back policy provides better system performance, because main memory is
accessed only when necessary to update the cache contents with changes in main
memory. Write-through policy accesses main memory every time data is handled by
the processor.
(c) Level 2 Cache
Use this option to enable or disable the level 2 cache.
