Abstract
A first firmware volume of a Unified Extensible Firmware Interface (UEFI) compliant information handling system is accessed. Authentication information is retrieved from the first firmware volume using a UEFI Secure Architecture Protocol. Based on the authentication information, it is determined if the first firmware volume is a first type of firmware volume. If the first firmware volume is the first type of firmware volume, the first firmware volume is authenticated using the first authentication information and an authentication procedure other than Secure Boot authentication. If the first firmware volume is a second type of firmware volume, the second type different than the first type, the first firmware volume is authenticated using the first authentication information and the Secure Boot authentication.
