BIOS together with EC firmware for the ASUS VivoBook Max X541SA notebook, archived as a 3.59 MB RAR. Having both images helps when a laptop shows no power, no display or keyboard faults, since the embedded controller firmware governs power sequencing, charging and the keyboard. The BIOS image goes to the SPI flash and the EC file to the controller or its own flash, using a suitable programmer. Check that the board revision on the PCB matches the X541SA, and dump the original contents before writing anything.
