Working BIOS for the ASUS Zenbook 13 UX331UN laptop, board revision 2.1, packed in a 16.7 MB RAR archive. No chip type or version is given in the name. The dump is meant for restoring a corrupted firmware by writing the SPI flash with a hardware programmer, for example when the machine powers on with no display after a failed update. Read and keep the original chip contents before flashing, make sure the extracted image matches the flash capacity, and check that the PCB is revision 2.1.
