Pre-Boot Network Settings

Use this option to configure a pre-boot network interface and related settings.


You do not need to use the Embedded UEFI Shell ifconfig command on a network interface if you plan to run webclient or ftp over the same interface because these interface and IP address settings are automatically selected by the Pre-Boot Network Settings configured in the System Utilities.

If the interface used by ftp and webclient happens to be configured by ifconfig, that setting is erased and, instead, the System Utilities Pre-Boot Network Settings menu is applied on the interface when the commands are run.

  • Pre-Boot Network Interface—Specifies the network interface used for pre-boot network connections.
    • Auto—The system uses the first available port with a network connection.
    • Embedded NIC—The system uses the selected NIC. If the selected NIC has more than one port, the system only uses the first available port with a network connection.
  • DHCPv4—Enables or disables obtaining the pre-boot network IPv4 configuration from a DHCP server.
    • Enabled—Enables DHCPv4 IPv4 network address configuration.

      This setting makes IPv4 address, subnet mask, gateway, and DNS settings unavailable because values are supplied automatically.

    • Disabled—Disables DHCPv4 address configuration, requiring you to manually configure the following static IP address settings.
      • IPv4 Address
      • IPv4 Subnet Mask
      • IPv4 Gateway
      • IPv4 Primary DNS
      • IPv4 Secondary DNS
  • Boot from URL—Specifies a network URL to a bootable ISO or EFI file. Enter a URL in either HTTP or FTP format, using either an IPv4 server address or host name. IPv6 addresses are not supported. When configured, this URL is listed as a boot option in the UEFI Boot menu. Then you can select this option from the boot menu to download the specified file to the system memory and enable the system to boot from the file.

    To use this setting:

    • Configure the pre-boot network settings to access the URL location.

    When booting from an ISO file, use a file that the system can use to boot a preliminary operating system environment, such as WinPE, mini-Linux, or VMware ESX installer. Doing so enables further installation to proceed over an OS network connection. ISO files that contain the full OS installation media are not supported.
