BIOS image for the HP ProBook 5300m on Quanta board DA0F11MB8D0, for an 8 MB flash chip and marked OK, packed in a 6.44 MB RAR. DA0 prefixes followed by a project code identify Quanta-made motherboards, and the trailing D0 reflects the board revision. Technicians write such a dump to the SPI chip with a programmer to revive a laptop with no display or boot loop caused by bad firmware. Back up the existing chip, verify the PCB marking, and note that serial and product data may need restoring afterward.
