GTX295显卡Mac完美驱动了现在放出驱动文件
Geforce GTX295是双核心显卡，显存也是分两份，和论坛上一般的范例都是单核心显卡不一样，所以无从借鉴，问题关键是要在显卡的两个物理位置各驱动一次，经网上搜索资料，终于找到了EFI驱动GTX295的方法，现在放出驱动文件，我亲自实践可行，QE/CI和分辨率全部开启。
希望对各位网友有用。
使用方法：先解压，用Kexthelper安装Kext文件（根据说明这个Kext实际上是GTX285的驱动，GTX295本身就是两组GTX285硬件组合起来），然后根据需要选择自己需要的Plist文件，双核心的用DualPCB,单核的用SinglePCB（295有单核心的我还没听说），我用的是DualPCB，根据实际的硬件位置用文本编辑它（注意是有两个位置的）。然后用GFXutil指令把.Plist文件生成.hex,（指令文件在压缩包里面）具体操作参考威廉第三的教程在用文本查看.hex文件，复制里面的代码，写在com.apple.Boot.plist的<key>device-properties</key>下面<string>......</string> ,重起，OK
加了以下dsdt，因为显卡是双芯片的，所以，我加了两种dsdt，但是去除了efi驱动，都不能驱动，可以进入系统，显示器信号中断，郁闷的要死！再就是加入dsdt后，我的pci设备显示出来n个gtx295卡，更是让我费解啊！希望懂的人帮我看看，提点一二，让我早日完美！
如下：我加入的dsdt显卡信息（双芯片）
