BIOS and EC firmware bundle for the ASUS FX63V and FX503VM gaming laptops, based on the Quanta board DABKLMB28A0, revision A. The DA prefix identifies Quanta numbering, and ASUS shares this platform between both models. The embedded controller image is useful for no-power, charging or keyboard faults, while the BIOS restores boot. Write each file to its own chip with a programmer, check the board number and revision on the PCB, and back up the originals before erasing.
