You should try that MOD, which was made for You, and post feedback with the results of whether is it working. That's what the MODs are done for. Вот так было бы вежливо.
Thanks. I will try it also. If the bios will not work, how difficult is restore original bios? I know that on old motherboards it was problem. What now? Also can I flash the bios if there will be older version, or is better first flash this not moded version?
