Firmware dump for the ASUS X550Z and X550ZE laptop, mainboard revision 2.0, packed in a 3.01 MB RAR file. A dump like this is written to the BIOS SPI chip with a programmer such as a CH341A when the original firmware is corrupted and the board will not start. Read and save the original chip contents first, since they hold serial numbers and other unique data. Check that the image size matches the flash chip capacity and that your board is a Rev 2.0 unit before writing.
