BIOS dump for the HP ProBook 450 G4 laptop on Quanta board DA0X83MB6H0, revision H, compressed to 5.99 MB. Quanta boards carry the DA0 prefix followed by the project code, here X83, and the revision letter at the end. The image is meant for reprogramming the SPI flash with an external programmer when the laptop has no display or loops on boot. Check the board label matches, save the original contents, and confirm the binary size equals the chip capacity.
