BIOS dump for a Sony VAIO laptop using the MBX-247 motherboard, supplied as a 4 MB raw binary that suits a 32 Mbit SPI flash chip. Sony identifies its VAIO boards with the MBX number printed on the PCB, though the underlying board may come from an ODM. The name gives no revision or version. Write the image with an external programmer to recover a board that does not POST, confirm the MBX number and chip capacity first, and save the existing contents before erasing.
