| If the router is stuck in ROMmon mode, the first setting that should be checked is the value of the configuration register.
| |
| The first four bits of the configuration register comprise the boot field. The value of the boot field defines the source of a default Cisco IOS® software image that will be used to run the router. If the value of the boot field is 0 (configuration register value of XXX0), on startup the system enters and remains in the ROM monitor mode (rommon>), awaiting a user command to boot the system manually.
| |
| If your router keeps entering the ROMmon mode each time the system is restarted, it is probably due to the setting of the configuration register. To verify the configured value of the configuration register, use the confreg command as shown below:
| |
|
| |
|
| |
| rommon 2 > confreg

|
| |
| As indicated by the output of the confreg command above, the configuration register is set to a value that forces the router to go into the ROMmon mode each time it is reloaded or power-cycled. To make the router boot automatically from a default Cisco IOS software image, change the configuration register value as shown below:
| |
| rommon 2 > confreg

|
| By doing this, you have changed the configuration register to a value that makes it look for a valid Cisco IOS software image on startup and boot from the same. The router must now be reset.

| If the configuration register value is set to make the system boot automatically from a default Cisco IOS software image, and if no break signal is sent during start up, the router should boot normally. However, if the router still enters the ROMmon mode, it is probably because the device is unable to locate a valid Cisco IOS software image.
| |
| The first thing you need to do then is to look for a valid Cisco IOS software image. To do this, issue the dir <device> command for each available device, and look for a valid Cisco IOS software image. For example, to look for the IOS in the Flash, use the command shown below.
| |
|
| |
|
| rommon 1 > dir flash:

| Note that if the router returns the "bad device name" message, the device specified probably does not exist. The output above indicates that a valid image is indeed present in the Flash. Try to boot from that image using the boot command.

|
| The router should now boot with the Cisco IOS software image specified in the boot command. However, there are times when a valid image does not exist on any of the devices or the image on the Flash might be corrupted. In these cases, a valid image has to be downloaded using Trivial File Transfer Protocol (TFTP) or by using the Xmodem procedure. Both these procedures can be carried out from the ROMmon mode.
