A firmware executes upon power on of a processing system and identifies any memory devices present in the processing system. The firmware then obtains uniquely identifying information for the memory devices such as, for example, part numbers and serial numbers. If the boot is the first boot of the processing system, the firmware transmits the uniquely identifying information for the memory devices to an endorsement service. The endorsement service, in turn, receives the identifying information and consults inventory data to determine if the memory devices are authorized for use in the processing system. The endorsement service then returns a response to the processing system that identifies any of the memory devices that are not authorized for use with the processing system. Upon receiving the response, the firmware disables any memory devices identified by the endorsement service as not being authorized for use with the processing system.

Endorsement of devices in a processing system

A firmware is configured with a firmware management protocol ('FMP') capable of updating a firmware logo image and a firmware logo image volume is defined within a firmware for storing a firmware logo image. A firmware logo image updater executing on a computing device receives a UEFI capsule that contains a firmware logo image. The firmware logo image updater stores the UEFI capsule in a UEFI system partition on a computer-readable storage medium accessible to the computing device. Upon a reboot of the computing device, the FMP is executed. The FMP retrieves the UEFI capsule from the UEFI system partition. The FMP then updates the firmware logo image volume with the firmware logo image stored in the UEFI capsule.
