BIOS dump for the HP ProBook 450 G4 built on Quanta motherboard DA0X83MB6H0, revision H. The DA0 plus MB pattern is Quanta numbering, with the letters and digits identifying the project and board revision. The 5.98 MB ZIP should contain an image for the SPI flash, useful when a board will not POST, after a failed update or after a chip swap. Before writing, confirm that the PCB reads DA0X83MB6H0 rev H, save the factory contents, and make sure the image size equals the flash chip capacity.
