Read of a Winbond W25Q128BV flash chip in a WSON8 package, taken from location U366 on 30 March 2021, giving a 16 MB BIOS image. The name does not state the laptop model or board, so its origin must be confirmed by inspecting the contents. A 16 MB image matches 128 Mbit chips only. WSON8 parts usually need a dedicated probe or hot-air removal for programming. Verify the platform strings in a hex or UEFI editor and back up the target chip before writing this dump.
