====== Burning iPXE into Intel network adapters ======

Intel provides a utility called ''BootUtil.exe'' which allows you to update the expansion ROM images on many Intel network adapters.

===== Preparing the tools =====

{{ :clipart:usbkey.jpeg?200x116|A USB key}}

Download and save the two files:

  * A FreeDOS boot disk image, [[http://boot.ipxe.org/burn/dosboot.img|dosboot.img]]
  * Intel's ''BootUtil.exe'' ROM-burning tool, formerly published directly by Intel but now available only from third-party sources such as [[https://dlcdnets.asus.com/pub/ASUS/lan/Intel_Gigabit_V16500_XPVistaWin7.zip|Asus]].

Copy your iPXE ROM image and ''BootUtil.exe'' to the FreeDOS boot disk:

    mcopy -i dosboot.img bin/808610de.rom ::
    mcopy -i dosboot.img Intel*/Driver/APPS/BootUtil/DOS/BootUtil.exe ::

where **bin/808610de.rom** is the iPXE ROM image that you have [[:howto:romburning|built]].

Transfer the bootable disk image to a USB key:

    dd if=dosboot.img of=/dev/sdX

where **/dev/sdX** is the device representing your USB key.  Please note that this will **erase** any existing contents of the USB key.

===== Burning the iPXE ROM =====

Boot from the USB key.  At the DOS ''A:\>'' prompt, type:

    bootutil -e

You should see a list of all Intel network adapters in your system, such as:

    Port Network Address Series  WOL Flash Firmware      Version
    ==== =============== ======= === =================== =======
      1   001B210A7760   Gigabit YES PXE                 1.0.13
      2   00270e0d5678   Gigabit YES PXE                 1.0.8

Identify the network adapter that you want to update.  For this example, we shall update adapter number 1 (which has address 001B210A7760).

Update the ROM on your selected network adapter:

    bootutil -nic 1 -restoreimage -file 808610de.rom

where **-nic 1** specifies your chosen network adapter, and **808610de.rom** is the iPXE ROM image that you have built.  You should see something like:

    A:\>bootutil -nic 1 -restoreimage -file 808610de.rom
    Intel(R) Ethernet Flash Firmware Utility

      2   00270e0d5678   Gigabit YES PXE                 1.0.8

Reboot the machine and enter the BIOS setup.  You should see iPXE show up as an option in your BIOS's boot selection menu.

Congratulations on successfully burning iPXE into your network card!
