The operating system software image file, identified by its .bin extension, is a non-readable, non-editable file that
executes on the system, creating its runtime operating system (OS).
executes on the system, creating its runtime operating system (OS).
It is important to verify a new operating system image file before attempting to load it. To accomplish this, a proprietary
checksum algorithm is used to create checksum values for each portion of the application stored within the .bin file
during program compilation.

This information can be used to validate the actual file against the checksum values stored within the file during its
compilation. If any portion of the image file has become corrupted (e.g. the file was truncated or was transferred using
ASCII mode instead of binary mode, etc.), then this information is reported and the file is deemed unusable.
