PXE-E51 only on USB dongle

[seth.jones]

Hello Everyone,
I am working on getting the Lenovo X1 Carbon in our environment, and I am having issues getting the pxe to pick it up. The only difference with the x1 is that i must use a USB NIC. I am getting PXE-E51 errors when it tries to boot from the NIC. I have the bios booting from legacy mode. When booting in UEFI mode I do get an ip address from the server to confirm that dhcp is working.

Additional Notes:
No other machine has had this issue
I have tried all of the usb ports just to be sure
DHCP/PXE options are in the dhcp server


I am convinced its an issue with the pxe server. Does anyone have any experience with this? Or suggestions?

Hi,

if no other client has this issue I don't think it is an issue of the pxe.
Do you use the Lenovo USB-Dongle?
Do you see a valid MAC-Adress on startup? With the Lenovo-Dongle I have a "00" in front of every octet which is ok.
