      option ntp-servers <ntp1>, <ntp2>;
      option routers 10.10.10.1;
      next-server <this_pxeserver>;
      filename "/boot/grub/x86_64-efi/core.efi";
    
      default-lease-time 600;
      max-lease-time 7200;
    }

    set timeout=5
    
    menuentry 'archlinux-2017.07.01-x86_64' --class os {
         insmod all_video

         net_ls_cards
         net_ls_addr
         net_ls_routes
    
         set root=http,<this_pxeserver>
         
         echo 'Loading Linux...'
         linuxefi /arch/boot/x86_64/vmlinuz archisobasedir=arch archiso_http_srv=http://<this_pxeserver>/ archisobasedir=arch ip=:::::eth0:dhcp
    
         echo 'Loading Intel micro code, initrd...'
         initrdefi /arch/boot/intel_ucode.img /arch/boot/x86_64/archiso.img

    mount archlinux-2017.07.01-x86_64.iso /mnt
    cp -R /mnt/* /var/www/html
  • Add UEFI Shell:
    mkdir -p /var/lib/tftpboot/boot/uefishell
    curl -OL https://github.com/tianocore/edk2/raw/master/ShellBinPkg/UefiShell/X64/Shell.efi
