APPENDIX

ROM Monitor

This appendix describes the Cisco router ROM monitor (also called the bootstrap

program). The ROM monitor firmware runs when the router is powered up or

reset. The firmware helps to initialize the processor hardware and boot the

operating system software. You can perform certain configuration tasks, such as

recovering a lost password or downloading software over the console port, by

using the ROM monitor. If there is no Cisco IOS software image loaded on the

router, the ROM monitor runs the router.

This appendix contains the following sections:

• Entering the ROM Monitor

• ROM Monitor Commands

• Command Descriptions

• Disaster Recovery with TFTP Download

• Configuration Register

• Console Download

Entering the ROM Monitor

To use the ROM monitor, you must be using a terminal or PC that is connected to

the router by means of the console port. Refer to the installation chapter in the

Hardware Installation Guide for your router, for information about connecting the

router to a PC or terminal.
