hello akcent, instand flash does not work. the asrock UEFI bios build in flash tool automatically searches all storage devices for matching bios files, even in subfolders. you have no choice to manual select a bios file. 1) asrock original files are found and working 2) yes, i have extracted the archive 3) mod bios is not recognized by buios build in flash tool i need either a mod bios which is recognized from instand flash flunction or a flash tool i can manually start from DOS. does the original bios has "special header" fro beeing recognized?
