  • Motherboards and methods for BIOS failover using a first BIOS chip and a second BIOS chip
    Patent number: 9542195
    Abstract: Systems and methods for BIOS failover. A processor reset is detected and a timer is set to expire after a predetermined time corresponding to a time to complete loading a first BIOS image from a first BIOS chip. Loading of the first BIOS image is initiated and it is determined whether the first BIOS image loaded successfully before the timer expired. If the timer expires before the first BIOS image is loaded successfully, loading is switched to a second BIOS image from a second BIOS chip. According to another aspect, loading of a first BIOS image from a first BIOS chip is initiated and a reset of a processor is detected. A reset counter is incremented in response to detecting a reset of the processor and loading is switched to a second BIOS image from a second BIOS chip when the reset counter reaches a reset threshold.
