ROM Monitor

Thisappendix describes the Cisco 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 perform certain configuration tasks, such as
recovering a lost password or downloading software over the console port, by
using the ROM monitor. If there is no Cisco IOS software image loaded on the
router, the ROM monitor runs the router.

router to a PC or terminal.
