BIOS firmware for the Sony VAIO VPCCW2S1E notebook, linked to the MBX-226 motherboard following Sony board numbering. The 1.01 MB RAR contains an image for reprogramming the BIOS flash when the laptop powers up without video or fails after an update. The name gives no version or chip type, so check the image size against the flash chip fitted to the board. Confirm MBX-226 on the PCB label, read out and keep the original contents, then write with an SPI programmer.
