Using the ROM Monitor
This appendix describes using the ROM monitor (also called the bootstrap program), which
is the firmware that runs when you power on or restart a Cisco 2600 series router. During
normal operation, the ROM monitor helps to initialize the processor hardware and boot the
operating system software. You can also use the ROM monitor to:
•
Help you isolate or rule out hardware problems encountered when installing your router.
•
Recover your router’s Cisco IOS image if the image becomes corrupted.

To use the ROM monitor, you must have access to the console port. See the Cisco 2600
Series Cabling and Setup quick start guide for information on connecting the console cable.
