BIOS firmware for the ASUS X555U notebook, packed as a RAR archive of 3.34 MB and labelled as tested and working. The name gives no board revision, so compare the revision silkscreened on the mainboard before writing anything. Technicians use such dumps to recover a board that will not post or shows a blank screen, writing the image to the SPI flash with a programmer such as a CH341A. Always read and save the original chip contents first, and confirm the image size matches the flash chip capacity, otherwise it will not fit or boot.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
