    You can get the rev 2.1 bios from Gigabyte support:

      Actually i have tried all 3 bios file from the official site and they are not working properly .
      the debug card is showing cod 15 and then restarting but to my experience and diagnosis it is the corrupt bios so i request if anyone have working bios please post it.

        The file you posted is 4MB in length: 4194304 bytes / 1024 / 1024 = 4MB
        The length on Gigabyte website is: 8388608 bytes / 1024 / 1024 = 8MB

        Please check what BIOS chip is installed on your board and verify your BIOS chip writer settings.

          All 3 files in official website are 4 mb and so is my chip is 25l32... so it is also 4 mb .
          there is no 8 mb but if you have 8mb bios for this mobo send it i will try with another chip of 25q64... Looking forward for help as Hansson's suggestion.

            The file you posted has a filename of GA-H61M-S1 REV 2.1
            The title of your thread is GA-H81M-S1 REV 2.1
            Please check your actual board model.
            The length I posted above was for board revision 1.0 by mistake, all others are 4MB as you say.

                If flashing the BIOS does not help then probably the problem is somewhere else.
                Or the problem is a hardware fault of the EEPROM, did you try to read it back after programming it and make sure it is the same?

                  It is very common for this type of board for bios corruption or internal byte of chip and actually from experience i got it working if i forcefully keep the psu on at code 15 then after few sec release it and i also boot into windows so my theory regarding it is the bios chip is internally damaged in this process some bits changed because of which i provided that file if anyone can repair it
