Abstract
A computing device is configured with a single memory device having multiple firmware images stored therein. At a boot time of the computing device, one of the firmware images is selected for use in booting the computing device. The selection of the firmware image to use for booting the computing device might be based upon the state of a hardware jumper, a board revision identifier, a silicon revision identifier, the results of a checksum operation, the presence or absence of one or more peripheral devices, user-specified settings, and/or one or more other factors. Firmware images might be stored in the single memory device in various combinations that include, but are not limited to, a fast-boot firmware, a full functionality firmware, a recovery firmware, a diagnostic firmware, a motherboard-specific firmware, an operating system-specific firmware, a pre-operating system operating environment firmware, an application-specific firmware, and/or a pre-operating system application firmware.
