## Overview

The lanutil.efi utility is used to update the option ROM on Intel PCI and PCI-E network adapters with a UEFI network driver image. The utility can also be
used to disable and enable the option ROM or to configure adapter Wake-On-LAN settings.

## Usage

lanutil [-up] [-nic=X|-all] [-wole|-wold] [-fe|-fd] [-blink] [-auto]

up | Programs selected network port with a UEFI option ROM.
nic=X|-all | Selects a specific port or all ports to perform operations on.
wole|-wold | Enables or disables WOL on the selected port.
fe|-fd | Enables/Disables boot ROM on the selected port.
blink | Blinks the LED on the selected port.
auto | Run all operations without confirmation prompts

| NOTES: If the -up parameter is specified without the -all or -nic=X parameters the utility will upgrade all networks ports previously programmed with an EFI option ROM. The -all or -nic parameters must be specified to reprogram an adapter that was not previously programmed with a UEFI driver. If called with no command line parameters a list of all supported Intel network connections will be displayed. lanutil cannot program LAN-on-motherboard (LOM) network connections with an EFI option ROM image. To use the EFI network driver on a LOM based network connection the driver must be loaded from a local disk partition using the shell "load" command, or be built into the platform EFI implementation by the platform vendor.

## Examples

- To force an update of all Intel network adapters found in the system to the UEFI network driver ROM image embedded in the utility with no confirmation prompts. (WARNING: This operation will erase an Intel Boot Agent or iSCSI Remote Boot option ROM image from the network adapter):

> fs0:\> lanutil -up -auto -all

- To update only the Intel Network Connections which have been previously programmed with an UEFI driver image:

> fs0:\> lanutil -up

- To disable the option ROM on port 1 to prevent the UEFI option ROM from loading during system boot:

> fs0:\> lanutil -nic=1 -fd

- To identify physical port 2 by using the LED blink function:

> fs0:\> lanutil -nic=2 -blink

- To disable Wake-On-LAN on all Intel Network Connections in the system:

> fs0:\> lanutil -all -wold
