Technologies for receiving and using alternate firmware files of a computer are described herein. In some examples, firmware files to be used instead of currently used firmware files are stored in a firmware volume, which is stored in a UEFI partition. A flag is set indicating the presence of a firmware volume containing the alternate firmware files. At boot time, if it is determined that the flag has been set, the computer will utilize files stored in the firmware volume stored in the UEFI partition rather than corresponding files in a firmware.
