BIOS dump for Wistron board 203037-2 with platform code MEL 8L and Wistron part number 448.0ML04.0021, provided in a RAR archive. The laptop brand is not stated in the name. Wistron's six-digit board numbers with a dash revision and 448-prefixed part codes appear on the PCB silkscreen. Confirm both before flashing. Read the original SPI chip with a programmer and keep the backup, and make sure the image matches the chip capacity so it fits.
