Firmware dump for the HP ProBook 450 G3 on motherboard DAX63CMB6D1 revision D, stored in a 5.64 MB ZIP archive. The DA-prefixed numbering belongs to Quanta, the ODM that designed this board, and the final letter together with the REV marking identifies the PCB revision. Technicians use such an image to recover a board with corrupted BIOS by writing the SPI flash directly with a programmer. Check that the silkscreen number and revision match, keep a backup of the existing chip, and confirm the file size equals the chip capacity.
