Burn the image to a CD using image burning software. Be sure the program burns the bootable iso image to the CD.

You should save your GUI configuration before you do the update.

MAINTENANCE -> miscellaneous -> Function: Save settings

Insert CD into CD-ROM drive

Set Bios to boot from CD

Boot System

When this menu appears select 1
1 Update with current settings kept (default)
2 Update with factory defaults settings

Update will take about 10 minutes

When you see this message
“Update performed correctly, please remove ISO-CD from your CD-ROM and reboot the system”

Remove the CD

Reboot system

Change BIOS to boot from USB drive.

System will boot into Open-e software

Upgrade is now complete.
