BIOS archive for the ASUS Vivobook X513EP laptop, with 16MV in the name, most likely referring to a 16 MB flash image. Before programming, read the marking on the SPI chip to confirm its capacity, since an image that does not match the chip size will not fit. Unpack the archive, use a programmer such as a CH341A to read and save the existing contents, then write the new image. Check the board model and revision silkscreened on the PCB to be sure it matches the X513EP.
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.
