#################################  安装原理  ########################################

- 从DHCP服务器获得IP地址，pxelinux.0文件和tftp服务器的位置；            ---> /etc/dhcp/dhcpd.conf
- 从tftp服务器获得pxelinux.0文件并启动                                  ---> /etc/xinet.d/tftp  &  pxelinux.cfg/default
- 从tftp服务器上获得memdisk和win7 pe iso                                ---> pxelinux.cfg/default
- 权限交给win7pe，执行install.bat                                       ---> install.bat  & winpeshl.ini
- 挂载samba服务器位置，并执行setup.exe开始安装程序                      ---> install.bat  &  /etc/samba/smb.conf
