ROM Monitor
This chapter describes the Cisco Catalyst 4500 series switch 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 use the ROM
monitor to perform certain configuration tasks, such as recovering a lost password or downloading
software over the console port. 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
• ROM Monitor Command Descriptions
• Configuration Register
• Console Download
• Debug Commands
• Exiting the ROM Monitor
Note For complete syntax and usage information for the switch commands used in this chapter, see the Cisco
Catalyst 4500 Series Switch Command Reference and related publications at this location:

If a command is not in the Catalyst 4500 Series Switch Command Reference, you can locate it in the
Cisco IOS library. See the Catalyst 4500 Series Switch Cisco IOS Command Reference and related

Entering the ROM Monitor
To use the ROM monitor, you must be using a terminal or PC that is connected to the router over the
console port. Refer to the installation chapter in the Cisco 806 Router Hardware Installation Guide that
came with the router to connect the router to a PC or terminal.
