Abstract
A computing device equipped with UEFI-compliant firmware is provided with added functionality via an extended firmware interface. The variable interface is called with special parameters, which redirect handling of firmware service calls. Embodiments use authenticated variables to provide security properties to the special interface, use the firmware interface to provide access to diagnostics, and use the firmware interface to provide access to system management.
