查看网卡信息，发现网卡运行闪存固件的功能被禁用：

tar zxf preboot_26.6.tar.gz 
cd APPS/BootUtil/
chmod +x Linux_x64/bootutil64e 

./Linux_x64/bootutil64e
Port Network Address Location Series  WOL Flash Firmware                Version
==== =============== ======== ======= === ============================= =======
  1   xxx     5:00.0 Gigabit YES FLASH Disabled
  2   xxx     5:00.1 Gigabit N/A FLASH Disabled

查看闪存固件信息，可见固件内包含PXE功能：

 ./Linux_x64/bootutil64e -IMAGEVERSION -nic 1
Flash firmware on port 1
PXE            v1.3.98

启用在端口1上运行闪存固件的功能：

./Linux_x64/bootutil64e -nic=1 -FLASHENABLE

重启系统就可以使用PXE引导了，查看网卡信息：

./Linux_x64/bootutil64e
Port Network Address Location Series  WOL Flash Firmware                Version

查看preboot自带BootIMG.FLB固件版本信息：

./Linux_x64/bootutil64e -IMAGEVERSION -FILE BootIMG.FLB

更新PXE固件，未经测试。

./Linux_x64/bootutil64e -NIC=1 -up=pxe -FILE=BootIMG.FLB 

开启WOL：

./Linux_x64/bootutil64e -nic 1 -WOLE
