ABSTRACT:
The control method names used in the advanced configuration and power management interface (ACPI) are modified to add control flexibility to the interface. The interface is between a basic programming system such as BIOS and an operating system, and the modification of the control method names controls the enabling of the control methods associated with control method names. During setup a user dialogs with the computing system and select settings for configuration and power management features for the system. The selected settings indicate the features corresponding to control method names to be modified. The control method names to be modified are searched for based upon the selected settings. The control method names found by the search based on the settings are modified so that the operating system will not recognize the control method names and the associated control method will not be enabled. The checksum in the modified control method name is updated to reflect the change in the name so that the checksum is correct and the modified control name will be valid.
