So basically i need to try the different bios setups combined with the different binaries in order to capture an Image of this Dell XPS13?
As I said, it’s probably a lot easier than debugging why undionly.kpxe doesn’t work at all and undionly.kkpxe has transfer issues…
So it’s all about the combination of Laptop, firmware and USB dongle. Here is a forum thread where someone was able to PXE boot in BIOS legacy (undionly.kpxe) with a USB dongle also based on the RTL8153 network chip. But as I said, it’s always a bit different as soon as you change one component in the equation.
And here Dell is saying that “The XPS 13 with BIOS A05 or higher, supports PXE boot with LAN7500 chipset based USB NICs.”
Just want to show you that there are many different ways and people were able to PXE boot the XPS13 but you can only know for sure when you test with the components you have at hand.
Edit: Hope this is not causing too much confusion. Just wanted to show you that there are different solutions out there and trying to do plain UEFI might be the easiest one or at least worth a try. Here is a thread where the same issue as yours is described and was solved by switching to UEFI.
