Abstract:
A method and system are disclosed to secure option read-only memory (ROM) configuration by calling a get user input function, determining if the user input is an option ROM configuration input sequence that allows a user to interact with an option ROM, performing one or more filtering checks on the user input, and conditionally returning the user input to the option ROM. The filtering checks are used to enforce security policies such as prompting for a password, blocking all option ROM configuration input sequence from reaching the option ROM, not allowing option ROM configuration in certain boot environments, and the like.
