Making a CompactFlash Disk-Based Software Image the Bootable Software Image

This section explains how to make a CompactFlash Disk-based Cisco IOS software image a bootable image.

After you copy a software image to the CompactFlash Disk, use the following series of commands to make the image bootable (the file named new.image in this example). The software image in this example is located on the CompactFlash Disk in slot 0. Note that the config-registercommand is also a part of this command sequence because you must set the configuration register to 0x2102 to enable loading an image from the CompactFlash Disk.

System# config terminal

System(config)# no boot system

System(config)# boot system flash disk0:new.image

System(config)# config-register 0x2102

Ctrl-Z

System# copy system:running-config nvram:startup-config

System# reload

When the system reloads, it boots the image new.image from the CompactFlash Disk in slot 0.
