Raw firmware image with an uninformative name, ZAS with a .fd extension appended to .BIN, giving no brand, model or board number. The binary is 8 MB, the size of a 64 Mbit SPI flash chip, and the .fd suffix is commonly used for UEFI firmware volumes. Without a model, identify the target by opening the image in a hex editor or UEFI tool and looking for version strings. Never write it to a chip blindly; first read and keep a copy of the original contents, and match the size to the installed flash.
