ASUS BIOS ROM covering the X553MA and X453MA laptops, with the name pointing to board revision 2.0 and version 210. The image is 1 MB, which is unusual for a full chip dump on this class of machine, so it may be an update image or partial region; compare it with the size of the installed SPI chip before programming. Technicians use such files to recover boards that no longer boot. Check the revision silkscreened on the PCB and back up the original contents first.
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.
