Cisco 2600 Series Routers Hardware Installation Guide

Appendix C      Using the ROM Monitor

ROM Monitor Commands

Verifying ROM Monitor Mode

To verify that you are in the ROM monitor mode, check that the prompt displayed on your screen is the 
ROM monitor mode prompt:

rommon # >

The 

#

 is the line number and increases incrementally at each prompt.

From the Cisco IOS software, you can configure the router to automatically enter ROM monitor mode 
the next time the router boots by setting virtual configuration register bits 3, 2, 1, and 0 to zero. From 
the console, enter the following configuration command:

configuration-register 0x0

The new configuration register value, 0x0, is effective after the router is rebooted with the reload 
command. The router remains in the ROM monitor and does not boot the operating system.

As long as the configuration register value remains 0x0, you must manually boot the operating system 
from the console. Refer to the boot command in the 

“Command Descriptions” section on page C-3

.

ROM Monitor Commands

Enter ? or help at the ROM monitor mode prompt to see a list of available commands. For example: 

rommon 1 >  ?

alias       set and display aliases command

boot        boot up an external process

rommon 2 >

The Cisco 2691 has these additional ROM monitor commands:

iomemdef 

set IO mem to a default 25%

rommon-pref select 

ROMMON

Note

You can end any command by pressing the Break key at the console.
