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.
