System and method for managing and diagnosing a computing device equipped with unified extensible firmware interface (UEFI)-compliant firmware

摘要

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.
