Whether or not you need to configure the computer with these options depends
primarily on the kind of software or peripherals you use.
(a) Power-up Modes
Use this option to choose between resume and boot mode. This option can
also be set by hotkeys.
Boot Turns on boot mode. (Default)
Resume Turns on resume mode.
(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 policy = Write-back
OPTION
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.

Use this option to enable or disable the level 2 cache.
