When i click the BIOS version i want to download it opens insydeflash normally but then it comes up with an error. IHISI: Flash write error in SMI! SMI Return Code: 0x25 i downgraded to a08 for no reason, just a test, now when i click on any bios version it comes up with the error.. i downgraded my bios perfectly earlier and it worked so i dont understand why this wont.. all i want to do is unlock my bios and disable damn hyperthreading so i can play a game. Any ideas ? i am pretty computer savvy but try and explain it simply!
