How do I enable dual graphics with my following information?


Cleared previous drivers with DDU.  Installed APU Crimson 16.3 with dGPU removed.  Installed dGPU.  Still no option for crossfire or dual graphics.  R7 250 shows up in Crimson but shows as disabled.


Instructions from motherboard manufacturer:

There is no dual graphics under the bios option. The new bios have option hidden.

sorry about the confusion.
