BIOS image for the ASUS X553SA notebook, an 8 MB binary; the name gives no version, board revision or notes on whether the ME region is cleaned. An 8 MB file normally matches a 64 Mbit SPI flash chip, which you would write with a programmer such as a CH341A after reading and saving the original contents. Check that the chip capacity on the board matches the file size, and keep the original dump, since it may hold serial numbers and other unique data that this image lacks.
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 @afsbiosfree. Enginerys does not host this file.
