原文作者:tluck
说明:本文以Lenovo T420作为原型,可以支持x220/t420/t520,另有额外的t420s提供扩展支持。
(这是原始教程,翻译下来很吃力,很多东西我自己也没办法解释,辅助翻译也是乱七八糟的,如果你成功安装了,参照我的简化版操作一下就行
简要理解就是:
(1).从github下载T420所需的文件,然后使用其中的EFI文件,选择适合你屏幕分辨率的config.plist文件,重命名为config.plist.
(2)恢复bios默认设置,系统更改为仅UEFI引导.
(3)制作USB安装盘,使用下载的EFI文件替换原有的Clover.
(4)使用引导安装系统,(安装盘的ESP分区剩余容量必须大于200M,否则格式化磁盘的时候会提示空间不足,格式化失败)
(5)安装完成后继续把EFI文件复制到本地硬盘的ESP,这时你的系统已经可以正常引导和运行
(6)这时候的系统可能没办法调整屏幕亮度和没有声音输出,再看看对应的部分修复一下
(7)至于其他的,自己慢慢了解之后再去看吧,需要积累一定的知识)
