2. To enable your router to boot properly, do one of the
following:
• Configure the software configuration register of the router
using the config-register value global configuration
command.
Set the boot ROM jumper to permit booting.
•
Include the correct boot system global configuration
•
commands to boot the system.
Set bit 0 to a value of 1 to force booting from ROM.
