dir flash:
[
partition-number
:
]
Use this command to list files in flash memory:
rommon >
dir flash:
File size Checksum File name
2229799 bytes (0x220627) 0x469e C2600-j-m2.113-4T
Note whether the new system image is the first file or the only file listed in the

command
output. ( is not required if the image is the first file or only file listed.)
Step 2
confreg 0x2102
Use this command to set the configuration register so that, after the next system reload or power cycle,
the router loads a system image from the
boot system
commands in the startup configuration file:
rommon >
confreg 0x2102
Step 3
boot flash:
[
partition-number
:
]
filename
Use this command to force the router to load the new system image:
rommon >
boot flash:C2600-j-m2.113-4T
