BIOS image for the ASUS X556UV, board revision 3.1, with the Intel Management Engine region cleaned, zipped to 3.72 MB. A cleaned ME region removes data tied to the previous machine, which helps avoid ME errors and slow boots after transplanting a chip or flashing a generic dump. Write it to the SPI flash with a programmer such as a CH341A. Confirm that the board revision is 3.1, back up the original chip first, and check that the image size matches the flash capacity.
