Zusammenfassung:An information handling system may include an embedded controller, a serial peripheral interface (SPI) read-only memory (ROM) device to store a first basic input/output system (BIOS) firmware for the information handling system, and a non-volatile memory device includes a boot partition to store a second BIOS firmware. The embedded controller detects a failure during a boot process, switches a first SPI of a chipset from the SPI ROM to the embedded controller and executes the second BIOS firmware from the non-volatile memory device via a sideband access of the non-volatile memory device.
