Zusammenfassung:	An information handling system embedded controller does not initiate a chipset having secure execution of chipset firmware unless the chipset firmware validates against error correcting checksums inserted into the embedded controller firmware. Comparing checksums calculated from chipset firmware against expected checksum values for the chipset firmware prevents secure chipset initiation failure due to bit errors associated with chipset firmware storage in flash memory.
