Title: DECbrouter90: Recovering from a lost "enable" password.

Product: DECbrouter90 V9.14/V10.x

Question: I've lost/forgotten the enable password for my DECbrouter90. How can 
          I recover this?

Solution:


        Recovery from a lost or forgotten "enable" password on the 
DECbrouter 90 is possible, as detailed below. Remember, like most systems,
*physical* access to the DECbrouter is as important as *software* safeguards.
The following information is taken from the DECbrouter90 documentation.

        To recover from a lost password:

1. Reboot the DECbrouter 90. While it is booting, hit the "break" key (usually
F5 on a DEC terminal). This will put you into ROM command mode, at the ">"
prompt.

2. Modify the configuration register from its default value of 102 to 142, as
follows:

        >e/s 2000002            !To examine value of config register
        >o/r 0x142              !To deposit 142 into config register
        >i                      !To initialize DECbrouter with new value

3. When the DECbrouter boots, it will ignore the existing configuration file,
and bring you automatically into setup mode. Answer "no" to the question "would
you like to continue with setup?" 

4. You will now be at the "Router>" prompt. Type "enab" to get enabled. You
will not be required to enter a password. You may now examine the existing
configuration file via the "show config" command, and can view the enable
password.

5. Type "config t", and enter the following command to restore the 
configuration register to its original value:

        config-reg 0x102
        ^z

6. Reboot the router via the "reload" command. You may now use the correct 
enable password to become enabled, and modify DECbrouter parameters as 
necessary.

        For more information on ROM mode commands, see Chapter 5 in the
DECbrouter 90 Getting Started guide, and page 4-21 in the Configuration and
Reference, Volume 1, or hit "?" at the ROM mode prompt (">").
