Firmware for the Sony VAIO VPCS11V9R, a Quanta GD3 board in revision D with Sony MBX labelling, stored as a 1.52 MB ZIP; the MBX number itself is not given in the name. Quanta produced the board, while Sony applies its own MBX codes. The image is used to reprogram the SPI BIOS chip with an external programmer when the notebook does not start. Compare the board code and revision printed on the PCB with the name, back up the existing chip and confirm the file size fits its capacity.
