Firmware archive for the Sony VAIO PCG-71211M, sold as the VPCEB1Z0E, with the MBX tag referring to the Sony main board designation; no exact MBX number or revision is given. At 1.63 MB packed it most likely holds an SPI BIOS image, possibly with EC data, for recovering a dead or locked VAIO. Unpack it, check the image size against the flash chip fitted on the board, compare the MBX number printed on the PCB, and save a backup of the original chip contents before programming.
