BIOS firmware for the ASUS X552CL laptop, board revision 2.1, labelled as tested fix. ASUS usually names its mainboards after the model with a revision number, so confirm the rev 2.1 marking on the PCB before using the file. A dump like this is used to repair no-boot or no-display faults caused by corrupt firmware through external SPI flashing. Extract the 3.5 MB archive, read the original chip first and keep a copy, then write the image and verify it, checking that its size matches 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 @generalbios. Enginerys does not host this file.
