ABSTRACT:
A method and article of manufacture for the run-time modification of Advanced Configuration and Power Management Interface ("ACPI") Machine Language ("AML") code in a Basic Input-Output System ("BIOS") of a computer system having an ACPI compliant BIOS. One aspect includes scanning all the AML code in the BIOS and finding all objects that meet a specified criterion, and modifying the AML that corresponds to the objects found based on the specified criterion. Another aspect includes scanning all the system code in a non-volatile memory of the computer system to determine device options modified by a user's preferences, and modifying the AML to reflect the user's preferences.
