Small ZIP archive of 332 KB labelled Quanta Z8I-C, apparently tied to the Quanta Z8I board family; the name gives no device model, revision or content type. At this size it most likely holds a boardview or similar layout data rather than a full firmware image, so check what is inside before use. Quanta project codes like Z8I appear in their DA-prefixed PCB numbers, which are printed on the motherboard itself. Match that marking against your board before using any part locations or measurements from the archive.
