If you set the boot field value to 0, you must boot the system manually by entering
the boot command at the ROM monitor prompt (rommon>).
If you set the boot field value to 0x2 through 0xF and a valid boot system
command is stored in the configuration file, the system boots the Cisco IOS
software image as directed by that value. If no boot system command is present
in the configuration file, the system computes a default boot filename for booting
from a network TFTP server.
In the following example, the software configuration register has been set to boot
the system from the Flash memory SIMM and to ignore the Break function at the
next reboot of the router:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# config-register 0x0102
Router(config)# boot system flash [filename]
Crtl-z
Router#
With the configuration register set to “0x0102,” the system creates a default boot
filename. In forming this filename, the system starts with the name cisco and
appends the octal equivalent of the boot field number, a hyphen, and the processor
type.
Recovering a Lost Password
This section tells you how to recover a lost password.
Note If the enable password is encrypted, the following procedure will not work for
password recovery and you will have to reconfigure the system before
attempting a reboot. To reconfigure the system, use the displayed
configuration obtained by entering the show startup-config command in the
privileged EXEC mode.
To recover a lost password, perform these steps:
Step 1 Attach an ASCII terminal to the console port.
Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 2 stop
bits (or to whatever settings the console port is currently set).
