A method for providing a secure firmware operating environment includes detecting the presence of a new component, for example, a peripheral device. Next, a determination is made as to whether the peripheral device includes an option read-only memory. Next, a determination is made as to whether the option read-only memory is authorized to be executed on the corresponding device. If the option read-only memory is authorized, the code contained within the option read-only memory is executed. By only allowing execution of peripheral devices or components including authorized option read-only memories, security related breaches are substantially reduced or eliminated; thereby, enhancing device integrity.
