Abstract:

A computing device includes a hardware switch that is activated when a primary Basic Input/Output System (BIOS) of a first BIOS chip of the device fails to load an Operating System (OS) image from an OS partition of a hard drive. The switch passes control to a backup BIOS that executes from a backup BIOS chip. The backup BIOS loads a recovery image from BIOS recovery partition of the hard drive, which causes a reflash application to execute from the recovery image. Reflash application obtains a recovery BIOS from the BIOS recovery partition of the hard drive, reflashes/writes the recovery BIOS onto the first BIOS chip and reboots the device. Following reboot of the device, recovery BIOS loads the OS image from the OS partition, and recovery BIOS becomes the primary BIOS on the first BIOS chip of the device.
