Whether or not you need to configure the computer with these options depends primarily
on the kind of software or peripherals you use.
(a) CPU Cache
Use this option to enable or disable the CPU cache.
Enabled
Disabled
When "Enabled" is selected, the following sub-window 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. When "CPU Cache" is
set to "Disabled", this option cannot be changed.
