You have an I/O controller with a good image in the onboard Flash SIMM so you can start the
Cisco 7206.
The bootable image you want to copy to the Flash memory card exists on a TFTP server to which
you have access (meaning you know its name and have connectivity to it), and at least one interface
is available over which you can access this server.
Note To ensure access to a TFTP sever, you will need to configure at least one network interface
using the setup command facility. For instructions on using this procedure, refer to
Chapter 4, "Performing a Basic Configuration of the Cisco 7206,"
Cisco 7206 Manually Using the Setup Facility" section on page
You know the filename of the image you want you want to copy onto the Flash memory card.
If you have already formatted a Flash memory card, you can use it instead; however, you cannot
boot from a Flash memory card that was formatted on another type of system. You must reformat
the card to use it as a boot source. To avoid potential problems when inserting spare Flash
memory cards in your Cisco 7206, we recommend that you reformat all of your Flash memory
cards on a Cisco 7206 running one of the recommended Cisco IOS software releases. The
