BIOS archive for the HP ProBook 440 G4 on motherboard DA0X81MB6E0 revision E. The DA0 number format belongs to Quanta, the ODM behind the X81 board. Use the dump to rewrite a corrupted SPI flash chip with a programmer when the laptop powers on with no display or will not boot. HP firmware stores serial and product data, so read and save the original chip first. Check that the image size matches the chip capacity and that the board revision on the PCB is E.
