Bios corrupted mobo biostar a70u3p due to unintended bios update, it happens after pc rebooted then automatically updating bios. Trying to reflash using external tool ch431a eeprom, since the bios size is 8mb for this mobo needed to convert to lower size. I can't find any uefi tool image viewer editor for this mobo. Or someone got backup bios file for this model plox send me a link. Thanks
