BIOS package for the ASUS S400CA laptop motherboard at revision 2.1, compressed into a zip archive of roughly 3.75 MB. The revision printed on the ASUS mainboard should match 2.1 before this image is used, as different revisions may need different firmware. Technicians flash the extracted dump to the SPI chip with a programmer to repair corrupted BIOS or no-display faults. Read and save the original chip contents first, and make sure the image size equals the flash chip capacity so it writes correctly.
