Sony VAIO BIOS for the MBX-237 motherboard, revision 1.3, marked as fully working and packed in a RAR of about 4.47 MB. Sony designates its laptop boards with MBX numbers, and repair shops commonly match the MBX code and revision rather than the retail model. The image is used to reprogram the SPI flash with an external programmer after a failed update or corruption. Back up the original chip before writing anything, and check that the file size corresponds to the chip capacity on your board.
