HP firmware package for Quanta board DA0AX1MB6F0 revision F, containing main BIOS and EC images according to the name, compressed as a 1.72 MB RAR. Quanta codes starting with DA0 identify its laptop mainboards, with the trailing letter-number giving the PCB variant. Having both the system BIOS and the embedded controller firmware helps when a unit has no power or charging faults caused by corrupt EC code. Flash each image to its own chip with a programmer, after backing up the originals and confirming the revision letter.
