Enable Network Connectivity During UEFI Pre-boot Authentication

For pre-boot authentication to succeed on a computer with UEFI firmware, the PBA must have network connectivity. By default, computers with UEFI firmware do not have network connectivity until the operating system is loaded, which occurs after PBA mode.

The following procedure enables network connectivity during PBA for UEFI-enabled computers. Because the configuration steps vary from one UEFI computer model to the next, the following procedure is only an example.

1. Boot into the UEFI firmware configuration.
2. Press F2 continuously during boot until you see a message in the upper right screen similar to "preparing one-time boot menu."

3. Enter the BIOS administrator password, if prompted.

   NOTE:

   Typically, you will not see this prompt if this is a new computer since the BIOS password has not yet been configured.

4. Select System Configuration.
5. Select Integrated NIC.
6. Select the Enable UEFI Network Stack check box.

7. Select either Enabled or Enabled w/PXE.

   

8. Select Apply

   NOTE:

   Computers without UEFI firmware do not require configuration.

Disable Legacy Option ROMs

Ensure that the Enable Legacy Option ROMs setting is disabled in the BIOS.

1. Restart the computer.
2. As it is restarting, press F12 repeatedly to bring up the UEFI computer's boot settings.
3. Press the down arrow, highlight the BIOS Settings option, and press Enter.
4. Select Settings > General > Advanced Boot Options.
5. Clear the Enable Legacy Option ROMs check box and click Apply.
