I promised feedback to BIOS update. OK… GA-H77M-D3H is fully working and supporting NVMe now 
. Used UEFI tool to insert drivers. Here is link to moded BIOS for everybody else. Used Ali Kingston NVME and Ebay PCIe interface . See speed comparison against Samsung EVO 850/512G. There is picture of BIOS boot choice.
Big thanks belongs to Fernando and everybody who made this nice hints how to…
