Secure boot override in a computing device equipped with unified-extensible firmware interface (UEFI)-compliant firmware

摘要

A firmware-based system and method for detecting an indicator of an override condition during a Unified Extensible Firmware Interface (UEFI) Secure Boot sequence. The indicator of the override condition may be detected based upon the pressing of a specialized button, designated key or keys or other received input that indicates both physical presence of the user and the desire, on the current boot, to bypass UEFI Secure Boot. An embodiment may work for only a single boot, not require access into a setup application, and may be accessed by externally accessible features of the computer system.
