A P P E N D I X C Using the ROM Monitor This appendix describes the ROM monitor (also called the bootstrap program), which is the firmware that runs when you power on or restart the Cisco 2600, Cisco 3600 and Cisco 3700 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.
Appendix C Using the ROM Monitor Entering the ROM Monitor Mode Tip From the Cisco IOS software, you can configure the router to automatically enter the 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.
Appendix C Using the ROM Monitor Entering the ROM Monitor Mode • If a minus option is followed by a colon (for example, [-s:]) you must provide an argument for the option. • A term in italics means that you must fill in the appropriate information. In the following example, you replace the term in italics with the interface type you are using: command type interface Command Descriptions This section lists some useful ROM monitor commands.
