HD4000EFI String驱动法，抛弃改版变色龙
附上HD4000的EFI String驱动法。
大概说一下，我看到了坛子里已经有了改版变色龙驱动的方法，这个方法不需要改版变色龙，只需要修改org.Chameleon.Boot.plist这个方法是在国外论坛上看到的，我尽量简单地去描述，让大家都看懂。
10.8已经正式对hd4000进行了支持，我的macbookAir就是用的这个显卡。我前不久更新换代买了Z77x up4 TH，但是回来发现ML貌似并不会自动给HD4000加载驱动，坛子里有不少朋友也碰到了这个问题，后来用改版变色龙解决了。但是改版变色龙并不一定能够驱动所有HD4000，如果您不想使用改版变色龙的话可以适用这个方法。
想驱动HD4000必须注入一个叫AAPL,ig-platform-id的东西才能加在10.8原生的驱动，否则驱动不会自动加载。这个方法如果使用正确的话一定能够驱动HD4000的，其实原理一样，只不过可以使用任意版本的变色龙或者奇美拉引导。
首先请看平台列表：

ig-platform-id: 01620005, Stolen RAM for FB: 32MB, Pipes: 2, Ports: 3, FBMem: 2
这些都是不同的管线端口配置的HD4000，至少有一个能成功注入驱动！而且台式机笔记本都可以使用！
如果你不知道该用哪个，首先你可以试试01620005，我的主板就是用05驱动的
使用方法：把以下其中之一代码填入到你的org.chameleon.Boot.plist里，并且按照表明的FB修改BIOS里的共享显存大小。
记住是显存（Internal Graphics Memory Size）的大小，不是DVMT的大小！DVMT大小永远设为MAX！并且在org.chameleon.Boot.plist 设置GraphicEnabler＝No

下面为举例：
比如我想试用05驱动我的HD4000
那么org.chameleon.Boot.plist的样子应该是这样的：
- <?xml version="1.0" encoding="utf-8"?>
- <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"[]>
- <plist version="1.0">
- <dict>
- <key>GraphicsEnabler</key>
- <string>no</string>
- <key>device-properties</key>
- <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string>
- </dict>
- </plist>
复制代码
然后在BIOS里设定显存大小为32M，重新启动，如果幸运的话，就应该能看到全分辨率的桌面了！
