Making a CompactFlash Disk-Based Software Image the Bootable Software Image
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.
If there is no
boot system
command in the configuration file, the router will try to load the default file
image from the CompactFlash Disk. For more information, see “Rebooting the Router” in the
Cisco IOS

manual.
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. 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.
