Entering The Rom Monitor - Cisco Catalyst 4500 Series Configuration Manual

ROM Monitor
This chapter describes the Cisco 806 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 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.
