image from the CompactFlash Disk. For more information, see "Rebooting the Router" in the Cisco IOS

Configuration Fundamentals manual.

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. Note that the config-register command 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.

The result of this configuration file entry is that the configuration register is set to hexadecimal

0x102. For more information on the configuration register, see the Cisco IOS Configuration

Fundamentals manual.
