BIOS firmware archive for the ASUS X550LC notebook, packed as a 3.16 MB RAR. The name gives only the model, with no board revision, BIOS version or chip type, so open the archive and check what image it holds before use. Technicians normally write such a dump to the SPI flash with a programmer such as a CH341A when the original firmware is corrupted. Compare the image size with the capacity of the chip on the board, back up the original contents first, and confirm the mainboard revision printed on the PCB matches.
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.
