Having a dummy cell in your saber doesn't necessarily mean you have an XT.
If your USB port is SEPARATE from your soundboard then its an XT. Otherwise it's not an XT.
Is this true even with FOC?
I just got a new saber with FOC and I am hitting the same point on the Obsidian Launcher. The video says it should say 64bit but mine doesn't... (unless its not an XT)
My board does not have a seperate usb port, but it also doesn't appear to have the big capacitor I have seen in all the pictures of non-XT boards...
