Booting from a Flash Memory Card
You can configure the router to boot from a Cisco IOS image on the Flash memory card, rather than from

Follow these steps to specify the image on the Flash memory card as the boot image:
Step 1 Enter privileged EXEC mode:
Router> enable
Password: password
Step 2 Enter global configuration mode:
Router# configure terminal
