Second copy of an 8.00 MB BIOS image tagged 8440 usoo, likely kept as an alternative read or backup of the same machine. The usoo token is not explained, and no board number or version appears in the name. Compare it byte for byte with the first copy in a hex editor or programmer software; differences can point to a corrupted read or a different configuration. Before flashing an SPI chip with this file, dump the existing contents and verify that the chip capacity matches the 8 MB image size.
