(b) CPU Cache
Use this option to enable or disable the CPU cache.
Enabled Enables the CPU cache. (Default)
Disabled Disables the CPU cache.
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-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.

Enabled Enables the level 2 cache. (Default)
Disabled Disables the level 2 cache.

processor at its fastest speed.

processor at low power consumption and low speed.
