Default Startup Characteristics

Each system ships with these default startup characteristics:

•

•

Configured system load paths

•

Enabled command interpreter input (CIIN) function

If the automatic system load is not successful, additional paths for loading are available

in the boot task. Using one load path, the system load task attempts to use another

path and keeps trying until all possible paths have been used or the system load is

successful. These 16 paths are available for loading, in their order of use:
