BIOS image for the Sony Vaio VPCCW series built on the Sony MBX-226 motherboard, stored in a 1.00 MB RAR. Sony labels its own laptop boards with the MBX numbering pattern, which is printed on the PCB. Technicians use such a dump to restore a corrupted firmware chip with an SPI programmer when the laptop powers on without display or will not start. Confirm the MBX-226 marking on the board, compare the image size with the flash capacity, and save the chip contents before erasing it.
