No Boot without nv_disable=1

[Riad]

Yeah for DVI is not working. My system definition is:

  Model Name:    iMac
  Model Identifier:    iMac11,3

How do I change system definition using clover?

Well figured out how to change the sys def, got it to boot by booting the USB clover but it won't stick. Here's a 5 min crud video, sorry about the long blank screen, basically shows how I booted using the USB and at the end there, how it hangs without the clover USB.
