ASUS X551M firmware, packed as a ZIP, for the X551MA mainboard at revision 2.0. The name separates the model from the board, showing that the X551M laptop uses the X551MA board. A technician uses this image to reflash a corrupted or blank SPI chip with a programmer when the notebook shows no display or will not power up properly. Before writing, confirm the PCB marking reads X551MA Rev 2.0, save the original chip content and check the extracted image size against the flash chip.
