1. A method, comprising:
sending, by a basic/input output system (BIOS) firmware included in an information handling system, a first request for a first hash value; responsive to receiving the first request, computing, by an embedded controller (EC) firmware included in the information handling system, the first hash value; sending, by the EC firmware, the first hash value to the BIOS firmware; when the BIOS firmware determines that the first hash value matches a first reference hash value, sending, by the BIOS firmware, a first confirmation to the EC firmware that the first hash value is accepted; responsive to receiving the first confirmation, sending, by the EC firmware, a second request for a second hash value; responsive to receiving the second request, computing, by the BIOS firmware, the second hash value; sending, by the BIOS firmware, the second hash value to the EC firmware; and when the EC firmware determines that the second hash value matches a second reference hash value, sending, by the EC firmware, a second confirmation to the BIOS firmware that the second hash value is accepted. |
