BIOS image packed in RAR for the HP ProBook 450 G3 on Quanta motherboard DAX63CMB6C0, about 4.5 MB compressed. The DA prefix marks a Quanta design, and X63 is the platform shared with related ProBook G3 models. Technicians flash such a dump onto the SPI chip with a programmer to revive a dead or bricked board. Save a copy of the original chip first, verify the dump size against the flash capacity, and make sure the PCB number matches.
