IN-SYSTEM PROVISIONING OF FIRMWARE FOR A HARDWARE PLATFORM

摘要

A hardware platform includes a nonvolatile storage device that can store system firmware as well as code for the primary operating system for the hardware platform. The hardware platform includes a controller that determines the hardware platform lacks functional firmware to boot the primary operating system from the storage device. The controller accesses a firmware image from an external interface that interfaces a device external to the hardware platform, where the external device is a firmware image source. The controller provisions the firmware from the external device to the storage device and initiates a boot sequence from the provisioned firmware.
