I am trying to PXE boot a XPS 13 9350 with a Dell USB 3 to Ethernet adapter (470-ABBT, which according to Dell is supported on the 9350 and able to use for PXE boot).
UEFI and SecureBoot is enabled.
I went in to the UEFI BIOS and under "Advanced Boot Options" checked "Enable UEFI Network Stack".
Saved and Restarted the machine.
Pressed F12 at the Dell logo, chose "USB NIC(IPV4)" under "UEFI BOOT".
The following appears in the top left corner:
>Check Media Precense.....
>>Start PXE over IPV4.
Then after a second or two the screen goes black and Dell SupportAssist appears, and starts running a system scan for hardware problems?!
Doesn't make any sense...
Thank you for writing to us!
We would suggest you to update the BIOS and then check if you have the same issue. If you do then there could an issue with the main system board ( motherboard )
Kindly private message the service tag and email address.
I just tried on another Dell XPS 13 9350 and on my Dell XPS 13 9343.
Both 9350 experience the same issue, SupportAssist starts scanning. The 9343 show that it couldn't start using PXE and gives me a few choices; F1 to restart etc.
Both 9350 use BIOS v.1.4.4 (which currently is the latest).
Since both the systems have the same issue kindly private message the service tags and email address and also mention the tags according to the systems. Also let us know if you have performed any troubleshoot steps.
Found that Dell released a new BIOS for the 9350 yesterday (22/11), version. 1.4.10.
Installed it, but it did not solve my problem. It delayed the start of the SupportAssist with maybe 10 seconds, but it still started when PXE boot didn't start fast enough. Very strange behavior.
