Sony VAIO firmware image in BIN form, zipped to 6.92 MB, with the name referencing EM_IW522 and version 6.0. The exact VAIO model is not stated, so confirm compatibility from the board markings or existing chip contents before use. BIN images like this are usually written straight to the SPI flash or EC chip with a hardware programmer when a laptop fails to power on or POST. Always read and save the original chip first, and verify the image size matches the chip capacity before flashing.
