Copying a Bootable Image onto a Flash Memory Card Chapter 5 Maintaining the Cisco 7206 Note For this example, an 8-MB Flash memory card was used, and at the line "Formatting sector," the system counted the card's sectors backwards from 64 to 1 as it formatted them. For 16-MB Flash memory cards, the system counts backward from 128 to 1, and for 20-MB Flash memory cards, the system counts backward from 160 to 1. Note For configuration information and descriptions of the commands used in this chapter, refer to the Configuration Fundamentals Configuration Guide and the Configuration Fundamentals Command Reference. Copying a Bootable Image onto a Flash Memory Card Once you have formatted a new Flash memory card, you can copy a bootable image onto it. The copying procedure assumes the following: • 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," the "Configuring the Cisco 7206 Manually Using the Setup Facility" section on page 4-3. • You know the filename of the image you want you want to copy onto the Flash memory card. Following is the procedure for copying a bootable file (called new.image in the examples) onto the Flash memory card: Step 1 Step 2 Boot the Cisco 7206 and allow it to initialize. Insert an unformatted Flash memory card into slot 0 (use slot 1 if slot 0 is not available) and format the card using the procedure in the "Formatting a New Flash Memory Card" section on page 5-9. Then proceed to Step 3. Note 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 "Reformatting a Flash Memory Card" section on page 5-12 section later in this chapter contains instructions that explain how to reformat a Flash memory card. Step 3 Copy the new image (new.image in the following example) to the Flash memory card and make this image the default boot image. Then reboot the router using the following series of commands: 5-10 Cisco 7206 Installation and Configuration Guide OL-5102-02
