Match the phases to the functions during the boot up process of a Cisco router. (Not all options are used.)

There are three major phases to the bootup process of a Cisco router:

1. Perform the POST and load the bootstrap program.
2. Locate and load the Cisco IOS software.
3. Locate and load the startup configuration file

If a startup configuration file cannot be located, the router will enter setup mode by displaying the setup mode prompt.
