Manually Booting the System
If your router does not find a valid system configuration image, or if you interrupt
the boot sequence, the system might enter read-only memory (ROM) monitor
mode and display the ROM monitor prompt (
rommon>
). From ROM monitor mode,
you have access to a number of commands to locate and boot a valid system
image.
