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:
1. 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.
2. If called with no command line parameters a list of all supported Intel
network connections will be displayed.
3. 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 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
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
