Using The Rom Monitor - Cisco 2800 Series Manual

Using the ROM Monitor

Many users do not use the ROM monitor at all, unless during power up or reload, the router does not
find a valid system image, the last digit of the boot field in the configuration register is 0, or you enter
the Break key sequence during the first 60 seconds after reloading the router.
This document describes how to use the ROM monitor to manually load a system image, upgrade the
system image when there are no TFTP servers or network connections, or for disaster recovery.
