Stuck iPXE initialising devices - .efi pxe boot

[philthynz]

Ok, i tried ipxe.efi from http://boot.ipxe.org/, and it has the same issue, it just stops at "iPXE initialising devices". snponly.efi boots, and i get the shell by pressing ctrl + b. But there are no network devices. ifstat does not show any device. I imagine the issue is still ipxe not being able to boot this particular network firmware. I can't see there is an issue with the Grub chainload, because on other devices it boots ipxe.efi fine, and on the shell ifstat shows the network devices.

I made a uefi ipxe usb with ipxe.efi, and that boots and ifstat shows the network adapter. So it seems to be related to network booting. Possibly with Grub's chainload which does something to the network adapter.

Is there another way to load ipxe from Grub? Or even boot Wimboot from Grub without ipxe?
