* Press Del again to get back into the BIOS
* Your flash drive should now be listed under the boot tab. Make sure Boot Option #1 is set to the flash drive.

Note: The next 3 steps are only relevant for larger Cincoze units. Smaller units such as the DA-1000 and DC-1100 may not have the PCH-FW Configuration menu. If the menu is missing, skip ahead to the Save & Exit step.

* Enable Me FW Image Re-Flash

* Save Changes and Exit
* The unit will now reboot and boot to the flash drive. If it reboots more than once, you will need to go back and enable Me FW Image Re-flash again. It only remains active for 1 reboot. This is a security feature.

* If this error message is displayed, the firmware re-flash setting was not enabled correctly. Allow the process to complete. Go back to that step and try again.
