Abstract
Validating code that is stored in non-volatile memory. In some instances, code that is written and/or processed by an outside entity that is brought into a local non-volatile memory setting can potentially compromise a given computer system. In order to ensure that this type of code is secure, there are methods to generate interrupt signals that can later be overridden by Otprom code in order to properly validate this outside code.
