ok, thanks for the explanation.
This case probably will not work for me, as I don't think I am allowed
to reprogram the BIOS of the machine(s) I'm targeting.

I wrongly had the impression that it was supported.
Thanks again for the clarification.
The reason I wanted to do it, was to get familiar with the U-Boot
build process and see the differences vs the EFI mode.

So, with the constraint that I have to not modify the existing BIOS,
it seems that the only way to put U-Boot on a disk image for x86 is to
use U-Boot as EFI payload.

Is this correct?
