Abstract
An information handling system includes a memory, a baseboard management controller (BMC), and a basic input/output system (BIOS). The memory stores a secure boot policy for a plurality of input/output (I/O) devices in the information handling system. The BMC performs a firmware update for a first I/O device of the I/O devices. In response to the firmware update being completed successfully, the BMC creates a system management task. During a next boot after the creation of the system management task, the BIOS detects the system management task. The BIOS calculates a new hash value for a firmware image of the firmware update. The BIOS replaces a previous hash value with the new hash value in the secure boot policy.
