ASUS BIOS image for the G531GU laptop, a 16.0 MB binary that matches the size of a 128 Mbit SPI flash chip, which suggests a full chip dump. No version number, ME status or board revision is given, so verify those before writing. A raw dump like this is programmed with an external tool such as a CH341A or similar programmer, using a clip or after removing the chip. Read and save the original contents first, since they hold serial, MAC and other board-specific data that a generic dump will overwrite.
