Fixing 290/390/470/480 boot problems with Intel Boards

If you are running this GPU on an Intel motherboard, you may experience boot problems in certain cases. Please see the guide below:

  • Do not use this GPU in the gpu0 slot. Instead, use another GPU.
  • Use a 16x16x ribbon riser in the gpu0 slot.
  • Use onboard video:
    1. set PRIMARY GRAPHICS to ONBOARD.
    2. set SHARE MEMORY to 32MB.

NOTE: If you use onboard video, POST will occur on onboard video, and the ethOS desktop will be displayed on gpu0.
