ROM, extracted from card0/device/rom

On a Gigabyte GA-A75M-UD2H mainboard with A8 3850 APU connectors reported by
radeon driver don't match those physically present.

The manual lists the following connector usage table:
- VGA   + DVI-D
- VGA   + HDMI    => only HDMI lit
- VGA   + DP
- DVI-D + HDMI
- DVI-D + DP      => only DP lit
- HDMI  + DP

In addition, mainboard allows configuring DVI-D output as Dual Link in which
case all other connectors would be disabled.


For full manual see

are descibed in chapter 1-7 on pages 20 and 21.
