BIOS dump for the ASUS X409MA laptop, mainboard revision 2.0, labelled as a working image and packed in an 11.7 MB RAR archive. The working status comes from the name and cannot be independently verified. Such dumps are typically flashed to the SPI chip with an external programmer when a board fails to post because of corrupted firmware. Save the existing chip contents before writing, check the image size against the chip capacity, and keep the original serial and identity data where possible.
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.
