A hardware implementation of the General Purpose Event status register supports the ability to assert, under software control, individual General Purpose Event status bits in a General Purpose Event register in an ACPI environment. Software control over the General Purpose Event register allows compensation of a platform electronic apparatus for design defects discovered late in the development cycle. Software control also enables the creation at any time of new "hardware events" which are then processed by the ACPI driver by means of manufacturer provided P-code. The ability to provide a software work-around for a wide range of ACPI related difficulties is advantageously created. Moreover, additional ACPI value-added features can thereafter be developed to differentiate and enhance ACPI compatible products.
