Hi! @Tito, all! I have flashed the modified bios, then in other to check if the flashing was successful I have extracted the freshly flashed bios from my motherboard through afudos again and opened it via UEFITool and, In the sencond listed: EfiFirmwareFileSystem2Guild/FV_MAIN_NESTED/Compressed section/Volume image section/EfiFirmwareFileSystem2Guild In the end of the folder I can see NvmExpressDxe Does it mean that I am now good to go? The bios doesn't detect my Nvme drive anyway. Is there anything that I am missing? Thanks for your help! S.
