Firmware dump packed in a 2.18 MB zip whose name, simply 8.bin, gives no hint about the device, board number or version it came from. Treat it as an unidentified binary until its contents are inspected with a hex editor or a BIOS tool to find vendor strings. Never write an unknown image to a working machine without first reading and backing up the existing chip with a programmer, and check that the extracted file size equals the capacity of the target SPI flash before attempting any write.
