Motherboards and methods for BIOS failover using a first BIOS chip and a second BIOS chip

A motherboard comprising:

• a first basic input/output system (BIOS) chip for storing a first BIOS image;
• a second BIOS chip for storing a second BIOS image;
• a platform controller hub (PCH);
• a peripheral bus connected to the PCH for communicating with a peripheral device;
• a processor in communication with the PCH;
• and
• a controller configured to control communication between the PCH and the first and second BIOS chips, wherein the controller is further configured to:
• determine whether the first BIOS image loaded successfully;
• and
• when the first BIOS image fails to load successfully:
• switch from loading the first BIOS image from the first BIOS chip to loading the second BIOS image from the second BIOS chip;
• determine whether the second BIOS image loaded successfully;
• and
• prevent the peripheral bus from resetting if the second BIOS image failed to load successfully.

A method for a basic input/output system (BIOS) failover comprising:

• initiating loading of a first BIOS image from a first BIOS chip;
• determining whether the first BIOS image loaded successfully;
• and
• when the first BIOS image fails to load successfully:
• switching to loading a second BIOS image from a second BIOS chip;
• determining whether the second BIOS image loaded successfully;
• and
• preventing a peripheral bus from resetting if the second BIOS image failed to load successfully.

A method for a basic input/output system (BIOS) failover comprising:

• initiating loading of a first BIOS image from a first BIOS chip;
• determining whether the first BIOS image is corrupted;
• and
• when the first BIOS image is corrupted:
• switching to loading a second BIOS image from a second BIOS chip;
• determining whether the second BIOS image loaded successfully;
• and
• preventing a peripheral bus from resetting if the second BIOS image failed to load successfully.
