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-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 in slot 0.
