Working BIOS archive for the HP 440 G3 laptop, labelled for the mainboard DAX61CMB6C0 revision C and described as fully tested. DAX61 board numbers follow the Quanta pattern used for many HP ProBook models. After extracting the RAR, the image can be written to the SPI flash with a programmer to fix a dead or boot-looping machine. Back up the original contents to retain serial and product data, verify revision C on the PCB, and check the dump size matches the flash chip.
