Firmware archive for the ASUS S400C and S400CA ultrabook, where the name ties it to the CPU onboard version with SLJ8E, the Intel S-spec of the soldered processor. Because boards for these models differ by soldered CPU, matching the S-spec helps pick the right image. Extract the RAR, verify that the image size equals the SPI flash capacity, and write with a programmer. Read and keep a backup of the original chip first so the serial number and UUID can be restored.
