BIOS dump for a Sony VAIO laptop with mainboard MBX-218, compressed in an 883 KB RAR file. No model, revision or version appears in the name, so match the MBX code and part number printed on the board itself. Sony uses MBX numbers to identify VAIO motherboards, and one MBX code can cover several retail models. A technician writes such an image to the SPI BIOS chip with a hardware programmer after a failed update or corruption, always after backing up the original chip and checking the image size against the flash capacity.
