Copying Cisco IOS Software Updates
As future releases of Cisco IOS software become available, you will receive these
images as a file booted from a network TFTP server, as a file on a floppy disk, or
as a file on a Flash memory card.
This section explains how to use a newly released Cisco IOS software image on a
Flash memory card in a system that has an older Cisco IOS image residing on a
Flash memory card inserted in PCMCIA slot 0 and a default Cisco IOS software
boot image stored in the onboard Flash memory SIMM on the RP.
In this procedure, you will copy an updated Cisco IOS software image from a new
Flash memory card onto a Flash memory card containing an old Cisco IOS
software image. In this example, the following filenames apply:
• image.new—The new image on the new Flash memory.
• image.old—The old image on the old Flash memory card inserted in
PCMCIA slot 0.
• image.boot—The bootable Cisco IOS software image stored in the onboard
Flash memory SIMM. (This image is used by default to boot the system if no
other bootable image is available.)
This procedure assumes that there is sufficient space on the old Flash memory
card inserted in slot 0 for both the new Cisco IOS software image and the old
image. If there is not enough space for both images on the old Flash memory card,
use the delete command to delete files from the old Flash memory card, but do
not delete the image.old file. After deleting files, use the squeeze command to
remove the deleted files from the old Flash memory card permanently. For
information on the squeeze command, see the “Flash Memory Console
Commands” section on page 3-69.
If the two files still will not fit on the Flash memory card in slot 0 after you delete
files and use the squeeze command, remove this card, place it in an antistatic bag
for ESD protection, and store it in a safe place. Insert the Flash memory card
containing image.new in slot 0. Proceed to Step 5 in the following procedure and
enter the command boot system flash slot0:image.new to designate the file
image.new as the new default Cisco IOS software boot image.
