What to you mean nothing?
You cannot even connect to the serial port or you cannot managed to
change the Configuration register to be able to make enable mode
password free and the change the one that you need.

Hi Bojan,

You may wish to investigate Cisco ROMmon Recovery Procedures.

http://www.bradreese.com/cisco-rommo...procedures.htm

Routers may go into ROM monitor ( ROMmon ) mode for any of these
reasons:

1. Boot failure.

2. The setting of the virtual configuration register forces the router
to stop in ROMmon mode during the boot.

3. A break sequence is sent to the console. The console will normally
ignore the break, except during the boot. However, the virtual
configuration register of the router may be configured to allow a break
sequence at all times.

For more information about the virtual configuration register, refer
to:

Configuration Register
