Firmware package for the ASUS X200LA mainboard, revision 2.1, delivered as a 3.33 MB ZIP archive. It most likely contains an SPI flash image for restoring a board that fails to start because of corrupt BIOS data. Extract the archive and inspect the binary in a hex editor or the programmer software before writing it to the chip. Read and archive the original flash first. Check that the board revision on the PCB is 2.1 and that the file length matches the chip density, otherwise it will not program correctly.
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.
