Combined BIOS and EC firmware package for the ASUS X409FB laptop mainboard, revision 2.0, in a RAR archive of about 5.19 MB. The embedded controller firmware handles power-on, charging, the keyboard and fan control, so pairing it with the main BIOS is useful when a board shows no power or charging faults. Program each image to its own chip with a suitable programmer after saving the original contents. Check that the revision on the PCB is 2.0 and that the file sizes match the chips.
