BIOS dump for the HP ProBook 450 G3 on Quanta board DA0X63MB6H1 revision H, labelled as fully working. The DAxxxxMBxxx code follows Quanta numbering and appears on the PCB, where the revision letter can be confirmed. Flash it with an SPI programmer to revive a board with corrupted firmware. Save the original chip contents first, since HP boards store serial and product data there, and make sure the file size equals the flash chip capacity before writing.
