Firmware archive for the ASUS X556UJ laptop, a 3.72 MB RAR whose name gives no board revision, BIOS version or working status. Extract it and check whether it holds a raw chip dump or a vendor update file before deciding how to use it. A raw dump is written to the SPI flash with an external programmer to recover a board with corrupted BIOS. Confirm the board revision on the PCB, read and keep the original chip, and make sure the image size equals the capacity of the flash.
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.
