HP 820 G2变色龙安装10.11.6基本完美
初始状态：
一块ssd硬盘，MBR格式分区，安装了WIN7 64位.
不想动win系统，因此就安装在硬盘的扩展分区
电脑配置：
cpu: i7-5600u
声卡: ALC280
显卡: HD5500
有线网卡: intel 218
无线网卡: intel ac7265(无法驱动，蓝牙免驱)
压缩磁盘、分区这些都不说了，主要就是分出两块来，一个用于写懒人版的cdr镜像，一个分区用于安装系统。
启动办法是使用EasyBCD增加一个菜单，然后在菜单中启动变色龙的光盘镜像。
这么做的目的是尽量少修改windows系统。
镜像取自http://bbs.pcbeta.com/viewthread-1702502-1-2.html

这个镜像里面的smbios是imac，
同时在e/e目录下的FakeSMC在hp 820 g2上运行有问题，我就换成新版本的，进了安装界面
安装后，修改dsdt基本是参照大神RehabMan的github上的说明修改的
参考https://github.com/RehabMan/HP-ProBook-4x30s-DSDT-Patch/blob/master/patches/02_DSDTPatch.txt进行修改
由于笔记本型号毕竟不一样，我基本上是看了这些修改点，然后手工修改dsdt完成整个过程。
其实这些补丁有点正则表达式知识的，都是能够看得懂的。
修改dsdtr的大致步骤如下：
Chameleon_2.3svn_r2839_Enoch_10.12_pkg+wowpc

安装时CDR中的FakeSmc.kext在820上会kernel panic，替换最新版本的FakeSmc后OK
DSDT修改：

修改DSDT及SSDT中涉及HDAU中的layout-id为4
在Extra/Extensions目录下需要放AppleALC.kext
将EC0下面16bit的变量拆分成两个8bit，同时修改使用这些变量的函数，添加B1B2函数（由于没有32BIT的，因此没有B1B4函数）
例如：BDC, 16, => BDC0, 8, BDC1, 8,Store (BPR, Local3) => Store (B1B2 (BPR0, BPR1),Local3)
在Extra/Extensions目录下需要放ACPIBatteryManager.kext
删除之前添加的PNLF设备
在IGPU下添加PNLF设备，相关信息从如下链接中取得
