Rom Monitor - Cisco Catalyst 4500 series Administration Manual

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.
