Abstract
In one embodiment a computer system comprises a processor, a basic input/output system (BIOS) including logic instructions which, when executed by the processor, configure the processor to create a virtual AML device data structure, the data structure comprising a plurality of fields to hold arguments to a native firmware function, store at least one argument for the native firmware function in a register of the AML device data structure, store an entry point and a pointer value in a register of the virtual AML device data structure, and initiate an access request to a firmware access register in the AML device data structure.
