Abstract
Methods of extending capabilities of authenticated code modules (ACM) with minimal increase in code size comprises defining an authenticated code module (ACM) extension module using an entry of a Firmware Interface Table (FIT). The FIT contains a starting address of the ACM extension module that is located outside of a protected boot block. Based on the ACM extension module having been authenticated, the ACM and the ACM extension module may be processed together.
