BIOS firmware for the ASUS X750LN laptop motherboard in a 4.51 MB ZIP archive; the name gives no board revision. The image is intended for direct programming of the SPI flash chip when the notebook shows no display or will not complete POST. Since ASUS mainboards come in several revisions, compare the revision printed on the PCB before use. Back up the existing chip first to preserve the serial number and MAC address, and confirm the image size equals the flash capacity.
