BIOS and EC firmware package for the ASUS X570DD laptop mainboard, revision 2.0, in a 7.77 MB RAR archive. The 8225E in the name most likely refers to the ITE IT8225E embedded controller, so the set covers both the main SPI BIOS and the keyboard/power controller firmware. EC corruption can cause no power, dead keyboard or charging faults, so both images matter. Match the board revision on the PCB, dump each chip before writing, and use the right programming method for the EC.
