Abstract
Systems and methods are disclosed for providing memory security override protection for improved manufacturability of information handling systems. A security authentication system is added to a software driven security override signal for unlocking programmable memory circuitry, such as flash memory, according to security protection techniques associated with the Intel AMT (Active Management Technology) architecture. This security authentication system disclosed requires authentication of software security override requests before they are allowed. More particularly, the systems and methods disclosed add specific BIOS (Basic Input Output System) code to check the security override status and the software security override request signals on boots of the computer system to make sure these requests are not coming from rogue elements within the computer system. If the authentication is validated, then the programmable memory circuitry is unlocked on the next boot of the system to allow for reprogramming.
