2.进入ME刷bios
BIOS的实质是一个程序，驻留在CMOS存储器（重复可擦写），但必须用BIOS厂商出品的专门刷新工具。刷写BIOS的过程就是用新版本的BIOS文件通过专门的刷新软件覆盖旧版本的BIOS文件，从而让相关配件获得一种软升级让你的配件支持更新，更多的协议，提供更好的硬件性能或消除硬件固有的Bug等。

3.树莓派
3.1 系统安装：netstat -antp，arp -a
1.内存卡插入读卡器再插入电脑的usb接口，将u盘格式化为FAT32格式。如果右击格式化没有FAT32，用格式化fat32工具：http://www.ridgecrop.demon.co.uk/guiformat.exe。树莓派系统官网：https://www.raspberrypi.org/downloads/raspbian/。下载完系统(1.9G)，用写盘工具（https://www.balena.io/etcher/或win32diskimager）将系统写入u盘，写完后不要格式化其他盘。
2.树莓派插上内存卡，接上网线或连上wifi（连wifi，eth0信息为空，因为没有连接网线，wlan0显示内网ip）用ifconfig查看网络。service ssh start开启ssh服务，树莓派默认用户名pi，密码raspberry，sudo netstat -antp可查看到当前有22端口即ssh端口被监听，这时可关闭显示器。
3.用自己电脑上的putty/xshell/securecrt新建一个ssh连接，pi@树莓派内网ip，可登录树莓派。如果忘了树莓派内网ip，可用win下cmd中输入arp -a查看局域网下所有ip和mac对应。
4.树莓派网线和要访问的机器网线插在同一个小型交换机上并且树莓派的串口连接机器，本电脑就可以连接树莓派再通过picocom -b 115200 /dev/ttyUSB0连接到机器。如果没有树莓派，本电脑插上机器的串口线（一端USB口，一端网口）后在设备管理器里看到COM号右击添加驱动，下载并安装驱动后，本电脑通过如下连接。
5.如下打开树莓派自带的图像化界面。
win端需安装vnc viewer。
6.如下点击树莓派自带的node red启动。
树莓派是一个完整的个人电脑，树莓派功耗非常大（相比于没有soc的单片机），物联网中要性能弱并能实现功能就行，所以树莓派处于物联网处于尴尬地位，只用于教学或做一个系统先在树莓派上试试。
树莓派4性能更强并有了usb3.0口和千兆网卡，用来做NAS，但做局域网中NAS不需要这么高性能，买个路由器就行且功耗比树莓派低的多。
3.2 花式点亮LED：node red控制如下3.3v这个是树莓派上的排座，连电阻的是自己买的空排座。
1.如下左边拖进一个gpio和两个inject。inject中选择数字1和0。
如下gpio中选择GPIO04-7管脚。点击右边部署按钮。
2.如下设置闪烁效果，0这个inject也要如下设置。
3.如下通过http接口实现小灯的亮灭。
如下action为on的话赋值为0。
如下点亮小灯，将on改为off，灯熄灭。
