Firmware package for the ASUS VivoBook 15 X542BA, the AMD-based version, containing the BIOS and the EC firmware according to the name. It is a 3.89 MB RAR archive. With both images, a technician can reprogram the main SPI chip and the embedded controller, which handles power-on, charging and the keyboard, when the notebook is dead or behaves erratically after a failed update. Use a hardware programmer, save the original contents first, and check that each image fits the capacity of its target chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
