ZIP archive with BIOS firmware for the ASUS X553MA notebook; the name gives no board revision or version number. At 3.23 MB compressed, it could hold an update file or a full SPI dump, so check its contents and image size first. Full dumps are written with an external programmer to bring back a board that shows no image; update files are applied via the built-in EZ Flash tool. Check the mainboard revision on the PCB and read the original chip before writing anything.
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.
