Hi Bojan,

You may wish to investigate Cisco ROMmon Recovery Procedures.

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

1. Boot failure.

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

2. 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
