Step1: Power on the switch, and backup the PicOS configuration files.

The prompt appears very soon after the system boots up. User needs to hit the Enter key fast enough to stop the boot process.

Hit any key to stop autoboot: 5 <Ctrl-C>

At the uBoot prompt, enter the following command to bring up the utility program.

=> run framboot

This boots through a Linux kernel
