sorry... Strange, but this method works fine for all Asrock x270 series mobo try BIOS recovery : 1. copy official (non modified) bios into the root directory of a USB flash drive (FAT formatted). (try a DOS bootable USB flash drive too). 2. Plug that USB flash drive into the your board (use USB 2.0 port), 3. plug in power cord & boot it up. System must start "BIOS Recovery" automatically. (try also 3. press Ctrl + home, plug in power cord & boot it up.)
Hello Serg008, "ASRock Crashless BIOS" does not recover with above methods. I flashed Bios Chip with "Flashrom" . 2nd Modded Bios works!! #2_Asrock H270M-ITX ac_2.50_Dell24_.rar thanks
