[Disabled] Disable this function. fC1E Support [Disabled] Enables or disables the C1E function for power-saving in halt state. This item appears when Intel C-State is enabled. [Enabled] Enables C1E function to reduce the CPU frequency and voltage for power-saving in halt state. [Disabled] Disables this function. fPackage C State Limit [Auto] This item allows you to select a CPU C-state level for power-saving when system is idle. The options of C-state depend on the installed CPU. This item appears when Intel C-State is enabled. fCFG Lock [Enabled] Lock or un-lock the MSR 0xE2[15], CFG lock bit.
