BIOS for the ASUS X455LJ with onboard memory disabled, supplied as a 1.91 MB ZIP archive. The file name gives no board revision, so verify compatibility against the PCB label and your original dump. Once flashed, the system ignores the soldered DRAM and boots using the memory slot, a typical repair for failed onboard chips. Write the extracted image to the SPI flash using a hardware programmer. Save the stock firmware first, as it contains serial number and MAC address data you may need to restore.
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.
