Firmware archive for the Sony VAIO PCG-71211W, a Core i3 machine with ATI discrete graphics on Sony board MBX-224. The 6.48 MB ZIP is larger than most single dumps, so check whether it holds multiple files before choosing the one to flash. Technicians use such images to recover a dead board by programming the SPI chip directly. Verify the MBX-224 marking and GPU fitment on the PCB, save the original chip contents, and confirm image size against the flash capacity.
