Abstract: A method includes modifying a basic input/output system (BIOS) to load a virtual general purpose input/output (GPIO) driver in an operating system, the virtual GPIO driver comprising at least one control method to monitor a system control interrupt (SCI) (202). The method can also include detecting the system control interrupt invoking the virtual GPIO driver (204) and executing the control method corresponding to the system control interrupt, the control method to be identified in the modified BIOS (206). Furthermore, the method can include detecting an error from the execution of the control method (208) and modifying an operating system to prevent the error (208), the modification comprising a modification to the control method.
