1. A method for altering a secure boot process in a computing device equipped with Unified Extensible Firmware Interface (UEFI)-compliant firmware, comprising:
identifying an interrupt command during a UEFI secure boot process for the computing device, the secure boot process interrupted in response to the command; displaying to a user, following the interruption of the secure boot process, a listing of at least one task related to altering the secure boot process; receiving a selection of a listed task; invoking System Management Mode (SMM) in response to the selection of the listed task; performing the selected task in SMM using a firmware module executable only within SMM; exiting SMM after the performing of the task, and booting the computing device after the exiting.
