Working BIOS dump for the ASUS X409DL laptop mainboard, revision 2.0, stored in a 10.7 MB RAR archive and described in the name as fully working. Technicians use an image like this to recover a board with corrupted firmware, such as one that powers on with no display or loops at startup, by writing it directly to the SPI flash with a hardware programmer. Before flashing, confirm the model and revision 2.0 on the PCB, back up the existing chip contents, and check that the extracted image size matches the flash chip capacity.
