Introduction
This document describes the procedure for recovering an enable password or replacing enable-secret passwords on Cisco 801, 802, 803, 804, 805, 811, and 813 Series Routers. These passwords are used to protect access to privileged EXEC and configuration modes. The enable password can be recovered because it is displayed in plain text in the configutaion file. The enable-secret password is encrypted in the configuration file and therefore can only be replaced with a new password.

You may encounter booting problems with the Cisco 801, 802, 803, 804, 805, 811 and 813 Series Routers. Cisco 801-805, 811, and 813 routers boot into TinyROM at power-up or after saving any configuration from the console port using Cisco IOS® Software Release 12.1(3) and later. For details of the affected unit serial number and the procedure to solve the booting problem, see Field Notice: Cisco 801-805 and Cisco 811 and 813 Boots into TinyROM.
Note: To recover a password on Cisco 806, 826, 827, 828, 831, or 837 Series Routers, refer to Password Recovery Procedure for the Cisco 806, 827, and 837 Series Routers.
Attach a terminal or PC with terminal emulation to the console port of the router. Use the following terminal …show more content…
Type set at the boot# prompt and record the current value of the configuration register (set by the "ios-conf" variable):
boot# set set baud =9600 set data-bits =8 set parity =none set stop-bits =1 set console-flags =0 set mac-address =0050.7307.C329 set unit-ip =10.200.40.65 set serv-ip =255.255.255.255 set netmask =255.255.252.0 set gate-ip =10.200.40.1 set pkt-timeout =8 set tftp-timeout =16 set boot-action =flash set file-name ="c800-nsy6-mw.122-10b.bin" set watchdog =off set prompt ="boot" set ios-conf =0x2102
!--- This is the value to record
Type set ios-conf = 142 at the boot# prompt.
If Flash is intact, the best setting is 142.
If the Flash is not installed or is erased, use the 141 setting.
Note: With this setting, you can view or erase the configuration, but you cannot change the password.
Type boot at the boot# prompt to initialize the router.
The router reboots but ignores its saved
