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