系统自动化安装

启动菜单介绍

Install or upgrade an existing system 安装或升级

Install system with basic video driver 在安装过程中发现显卡驱动不支持，造成屏幕无法显示，这时选择第二项，加载最基本的显卡驱动，这样让界面能够显示出来

Rescue installed system 救援模式

Boot from local drive 从本地硬盘启动

Memory test 内存的检查

这几项的区别就在于加的参数不同

选择一项，按 tab 键就可进入编辑模式

按 esc 键，在这个画面可以直接输入指令，指令为光盘文件的 isolinux/isolinux.cfg的 label 名

五个标签对应光盘开始菜单的五项

系统安装

询问系统安装源

安装程序启动过程

MBR：isolinux/boot.cat

stage2: isolinux/isolinux.bin

配置文件：isolinux/isolinux.cfg

每个对应的菜单选项：

加载内核：isolinuz/vmlinuz

向内核传递参数：append initrd=initrd.img ...

装载根文件系统，并启动anaconda

默认启动GUI接口

若是显式指定使用TUI接口：向内核传递text参数即可

(1)按tab键,在后面增加text

(2)按ESC键：boot: linux text
