Archive with both BIOS and EC firmware for a board marked GK5CN6X, version 1.1, about 4.99 MB as a rar. The GK5CN naming is used on Tongfang-made barebone laptops sold under various brands, though the file does not say which retail model it belongs to. Having the embedded controller firmware alongside the BIOS is useful when a machine shows no power or charging faults caused by a damaged EC image. Flash each image to its own chip with a programmer and back up both originals first.
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.
