Power-up Mode
This option lets you choose between Resume and boot mode.
These settings are for the MS-DOS environment only. When you use
Windows, settings made in Power Saver will be used.
CPU Cache, Level 2 Cache
Use this feature to enable or disable the CPU cache and to set the
write policy.
Level 2 Cache and Write Policy are activated only when the CPU
cache is enabled. Disabling the CPU cache also disables these features.
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. The write policy
option is used only for the CPU cache.
CPU Cache Options Enabled: Enables the CPU cache. (Default)
