Abstract
A system and method of improving security during power-on-self-test (POST), particularly the ROM scan portion identifying ROM adapters, while selectively allowing user input. While a user input during ROM scan may be normally locked out to prevent the user from making changes to the configuration of the system, when the ROM scan during POST detects a ROM adapter which uses an input from the user, the system can override the lockout and allows for a user input. An optional control, such as a password or other personal identifier, can provide security, allowing the user input only when the user is authorized to provide the input (in response to an appropriate password or personal identifier such as a biometric identifier).
