ROM-Monitor Command-Line Interface
The ROM-monitor is a ROM-based program that executes upon platform power-up, reset, or when a fatal
exception occurs. The router enters ROM-monitor mode if it does not find a valid software image, if the
NVRAM configuration is corrupted, or if the configuration register is set to enter ROM-monitor mode.
From the ROM-monitor mode, you can load a software image manually from Flash memory, from a
network server file, or from bootflash.
You can also enter ROM-monitor mode by restarting and pressing the Break key during the first 60
seconds of startup.
Note The Break key is always enabled for 60 seconds after rebooting, regardless of whether the Break key is
configured to be off by configuration register settings.
To access the ROM-monitor mode through a terminal server, you can escape to the Telnet prompt and
enter the send break command for your terminal emulation program to break into ROM-monitor mode.
Once you are in ROM-monitor mode, the prompt changes to rommon 1>. Enter a question mark (?) to
see the available ROM-monitor commands.
For more information about the ROM-monitor commands, refer to the Cisco 7600 Series Router Cisco
IOS Command Reference publication.
