Copying Bootable Images between Flash Memory Cards
When the system reloads, it will boot the new.image file from the Flash memory card.
This completes the procedure for copying a bootable image onto a Flash memory card.
Copying Bootable Images between Flash Memory Cards
As future releases of Cisco IOS images become available, you will receive these images either as a file
booted from a network server, a file on floppy disk, or a file on a Flash memory card.
The following scenario describes how to use a newly released image on a Flash memory card in a system
that has an older image on a Flash memory card in slot 0 and a default boot image in the onboard Flash
SIMM.
For this scenario, the filenames are as follows:
•
The new image on the new Flash memory card is new.image.
•
The old image on the Flash memory card in slot 0 is old.image.
•
The bootable image in onboard Flash memory is boot.image.
You will copy the new image from the new Flash memory card onto the Flash memory card that contains
the old image.
Note
The scenario assumes that the new image will fit on the Flash memory card in slot 0, alongside the old
image. If there is not enough available space, use the delete command to delete files from the Flash
memory card to make sufficient room for the new image; however, do not delete the old.image file. Then
use the squeeze command to remove these deleted files from the Flash memory card. If, after you have
deleted files and used the squeeze command, the two files cannot coexist on the Flash memory card in
slot 0, remove this card (place it in an antistatic bag and store it in a safe place), then insert the new Flash
memory card (with the file new.image) in slot 0. Proceed to Step 5 and use the command boot system
flash slot0:new.image to designate the file new.image as the default boot image.
Step 1
Boot the Cisco 7204. By default, the file boot.image is used.
Step 2
Enable the router as follows:
Router> en
Password:
Router#
Step 3
Insert the new Flash memory card in slot 1.
Step 4
Use the following command to copy the file new.image in slot 1 to the Flash memory card in slot 0, only
if there is enough memory space for the two images to coexist. If there is not enough memory space,
proceed to Step 5.
Router# copy slot1:new.image slot0:new.image
Note
You can also enter the preceding command as copy slot1:new.image slot0:
