Firmware image named only 0188b, 4.00 MB in raw binary, with no brand, model or board number in the name. The meaning of the token is not clear, so the file must be identified by its content. A 4 MB size fits a 32 Mbit SPI flash chip. Open it in a hex editor or BIOS tool to search for model and version strings, then compare with the laptop and board you are working on. Always read and store the existing chip content before programming anything over it.
