操作步骤

在Opencore 0.6.6尝试了此方法，以帮助那些不希望介绍Ati图形卡的朋友

1.首先，我们将下载amd7000controller.kext文件，放在我给OC对应的驱动文件夹中

2.然后，我们使用OpenCore Configurator打开config.pls，并将AMD7000Controller.kext放入Karnel中。

3.继续用OpenCore Configurator来创建bot参数：Radpg=15 -lilubetaall

4.然后到DeviceProperties-device部分-PciRoot(0x0)/Pci(0x2,0x0) - AAPL，AAPL,ig-platform-id ，最后是value部分： 683F1002并保存config.pls。

5.它可以在我的显卡上运行，希望它对您有所帮助，不仅dvi可以工作，而且只有显示端口也可以在HDMI显卡上工作
