Small RAR archive of 2.16 MB filed as BIOS firmware and named only 64 alt 2. The 64 likely refers to a 64 Mbit flash, but that is not certain, and no brand, model or board number is given. Treat it as an unidentified alternative image. Inspect the contents after extraction before use. Confirm the target board, match the image size to the chip, and save a full read of the original chip before programming.
