BIOS firmware for an HP ProBook 450 G4 mainboard numbered DA0X83MB6H0, revision H, packed as a 5.05 MB RAR archive. The DA0 prefix with MB is the Quanta board numbering scheme, Quanta being the ODM that built this board for HP. Technicians write such an image to the SPI flash with a programmer to recover boards with corrupted firmware. Confirm the board number and revision on the PCB, back up the original chip, as it may store serial and product data, and ensure the image fits the flash size.
