The first question asked is whether you wishto change the configuration, meaning whether you want to change the configuration register values: answer y to continue. For the question "Do you want to ignore system config info "n, if you answer y, the third hexadecimal bit will be 4, so that the router's configuration register value will be 0x2142. Use this value when you want to perform the password recovery process. The penultimate question is "Do you want to change the bootcharacteristics?", and if you answer y, these questions will be repeated. If you answer n, you will exit the script. If you make changes, you will be asked if you want to save the configuration (do you wishto change the configuration?). Answering y will save the new configuration register value. After modifying the configuration register values, reboot the router. On many routers, reboot by simply entering the letter i or b in ROMMON mode.To perform the password recovery process, you need to enter ROMMON mode and change the configuration register value to 0x2142, then reboot the router. When rebooting, the router will ignore the configuration in NVRAM and enter the system configuration dialog. Press Ctrl-C to exit the script and enter user EXEC mode. Enter privileged EXEC mode and use the command copy startup-config running-config to restore the configuration. The command no shutdown is not listed in the router's NVRAM configuration, so you must enable the interface manually. You must also do this when copying and pasting the configuration to a router whose interfaces have been disabled (such as a router that has just booted).Authentication Target 15.0315.3 Disabling Unused Services
