Archive for the HP ProOne 440 G5 all-in-one computer, about 15.9 MB, with no board number, revision or content type given in the name. It may contain BIOS images, schematics or service material for this model, so open it and check what is inside. Match the motherboard part number and revision on the PCB before use. For firmware, save the original SPI contents with a programmer first, because HP stores serial number and product data in the chip, and verify that image size equals chip capacity.
