zYou cannot modify the file type of the type S application image file, but you can modify the file type of type M or B and N/A application image files in the Boot Rom menu or using commands after the application image boots.

zSecure boot file is the last system boot resort. You can download it in the Boot Rom menu and must name it secure.bin. However, you cannot modify this file or change the type of another file to S. If you change the name of the secure boot file with the rename command after the system boots, the file is removed from Flash memory. To use the secure boot file after that, you need to download it again.

For example, after you select option 3 from Boot Menu, the console screen displays a menu similar to the following:
