Working BIOS dump for the HP ProBook 440 G8, Quanta motherboard DAX8QAMB8D0 revision D, archived as a 10.8 MB RAR. The name says the image was tested and working. Quanta codes boards in this DA...MB pattern, and the full code is usually printed near the PCB edge. Technicians write such a dump to the SPI flash with an external programmer to recover a board that fails to start. Save the original contents first, since they may hold the serial number and other board-specific data.
