Firmware image for the HP ProBook 450 G4, designed around the Quanta motherboard DA0X83MB6H0 at revision H. The DA0 prefix with MB is Quanta's typical numbering for laptop mainboards made for HP. Technicians use such a dump to revive a bricked board or to replace a damaged BIOS region with a programmer. The 7.21 MB rar should be checked against the flash chip's capacity before writing. Back up the original chip first, because it holds the serial number and other system identifiers.
