(1) 製作網路開機隨身碟：
(1-0) 置入隨身碟並用df或lsblk指令察看得知為隨身碟的裝置代號為/dev/sdd
(1-1)用parted在/dev/sdd建立出分割區/dev/sdd1：
$ sudo parted /dev/sdd -s mklabel gpt mkpart EFI FAT16 1MiB 100% toggle 1 boot
(1-2)用mkfs在分割區(/dev/sdd1)建立msdos檔案系統：
$ sudo mkfs -t msdos /dev/sdd1
(1-3)將/dev/sdd1掛在$HOME/mnt
$ sudo mount /dev/sdd1 $HOME/mnt
(1-4)重編產生新的 bootx64.efi
$ cd $HOME/ipxe/src
$ vi ipxe/init.ipxe
$ cat ipxe/init.ipxe
#!ipxe
prompt --key 0x02 --timeout 9000 Press Ctrl-B for the iPXE command line... && shell ||
set prefix file:///linux
chain ${prefix}/boot.cfg ||
$ make clean
$ make bin-x86_64-efi/ipxe.efi EMBED=../init.ipxe
$ cp bin-x86_64-efi/ipxe.efi $HOME/esp/efi/boot/bootx64.efi
(1-5)將$HOME/esp目錄檔案全部拷到新掛上的隨身碟中：
$ sudo cp -r $HOME/esp/* $HOME/mnt
(1-6) $ df

(2)設定用戶端機器（client machine）的 BIOS以usb隨身碟優先開機並以剛製妥的usb碟開機
(3-0) 開機過程中，在伺服端執行arp及ifconfig
