I have tried several versions of the qube 3, but with no luck. Any ideas to get it to work. I usually geta kernal panic or it just reboots. I have tried different 3i with no success.
You may need to upgrade the ROM first... I know others had problems putting the RaQ 4 OS on an early RaQ 3 due to the old ROM not supporting newer features... downside is you'll have to restore it back to a RaQ 3 first, upgrade the ROM, then restore it as a Qube.
You can check the ROM revision when you have the RaQ 3 OS installed by doing cmos -c romrev
