NOTE: Dell Docks that utilize Display-Link drivers (for example, the D6000 series and D3100) will not allow PXE boot. Drivers for these docks do not load in a pre-Windows environment. While Dell does not recommend you PXE boot through a dock connection, you can accomplish this using a USB Type-C to Ethernet dongle (such as Dell SKU# 470-ABND) to complete PXE boot.
