A P P E N D I X B Using the ROM Monitor This appendix describes the ROM monitor (also called the bootstrap program), the firmware that runs when your Cisco 3700 series router is powered up or reset. 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 isolate or eliminate hardware problems and recover a corrupted Cisco IOS software image.
Appendix B Using the ROM Monitor ROM Monitor Commands The two methods of entering the ROM monitor mode are as follows. Enter ROM Monitor Mode by Using the reload Command Connect to the router from a console, and follow these steps: Step 1 Restart the router with the reload command. Router# reload Step 2 Press the Break key during the first 60 seconds of the system booting.

The first image in CompactFlash memory is invoked if the ROM monitor does not recognize a device ID specified in the boot command. The router cannot boot if there is no Cisco IOS software image in CompactFlash memory.
Appendix B Using the ROM Monitor ROM Monitor Command Descriptions • boot slot1:3: filename—Boots from the specified Cisco IOS software image in the third partition in the CompactFlash memory card in slot 1. • boot filename tftpserver— Boots from the specified Cisco IOS software image on the specified TFTP server (after first booting from CompactFlash); for example: boot c3725-is-mz 172.15.19.

Debugging Commands in the ROM Monitor Most debugging commands are functional only when Cisco IOS software has crashed or failed to initialize (boot). Debugging commands should normally be entered only under the direction of a Cisco engineer.
Appendix B Using the ROM Monitor ROM Monitor Command Descriptions In either case, the new configuration register value is written into NVRAM, but is not effective until you reboot (using the ROM monitor reset command) or power cycle the router. Modifying the Configuration Register in Menu Mode Entering the confreg command without an argument displays the contents of the configuration register, and prompts you to alter the contents by describing the meaning of each bit.
Appendix B Using the ROM Monitor Recovering Cisco IOS Software Images Recovering Cisco IOS Software Images If both the boot and system images have been erased and only the ROM monitor is available, you can use the ROM monitor xmodem command to copy a Cisco IOS software image to CompactFlash memory from the console. The console can be connected directly to the router through the console port, or remotely through a modem connected to the auxiliary port.
Appendix B Using the ROM Monitor Recovering Cisco IOS Software Images Procedure for the xmodem Command To copy the Cisco IOS software image from a console to CompactFlash memory, perform the following steps: Step 1 Connect the console using the instructions in the “Connecting to a Console Terminal or Modem” section on page 3-22. Step 2 Power up the router. The power-on self-test diagnostics run, and the boot ROM searches for a valid boot image and Cisco IOS software image in CompactFlash memory.
