    2102 is normal startup.
    2142 makes the router boot from flash without using NVRAM. It will start in setup-mode, so you can do certain stuff from there. This is what you wanna do if you need to recover your password.

    Funny book you have there if it doesn't mention that.

    Read the documentation and use this decoder. You can find the answers with Google and it'd be much quicker than posting here and waiting for a reply...
