I can second to that. I installed a SuperMicro X10SLM-F based server last month and did not find any option in the BIOS to PXE-boot FAI into UEFI mode. Ended up using disklabel:gpt-bios and GRUB_PC. I did not try to boot off an USB stick, so it is worth investigating if an option exists for booting that in UEFI mode.
>From my experiments I was left with the impression that it is not easy (or even possible) to "cross-install" UEFI-boot-capable disk if the system was booted into legacy (BIOS) mode. If someone has found a way to do it, I would also appreciate suggestions.

I am pretty sure this depends on how the installation was started. That means you will have to boot your FAI installation using UEFI as well. This can be a bit tricky if you want to install from network - I also tried setting up PXE with UEFI some time ago and failed. Bye, Andreas
