    The problem is how do I use 8 pin clip on this bios chip with 16 pins. I have ordered a 16 pin clip and is on the way..but another question arises...how do I connect this 16 pin clip to the Ch341a?

    Thanks for any solution
    I have same problem as yours. How to connect 16pin clip to Ch341a?

      Google for pinout and match it with soic8 pinout. They have those same 8 pins.

        The chip with no scratches is not original, bought on ebay, and caps lock blinks 7 times with it. Is it because the numbers arent the same? The scratched one has a password and boots fine

          The chip is exactly the same, so if you have problems, check the soldering (try to resolder the chip), or simply the chip is not programmed correctly.

            Compare the picture on the left where the chip is on the pads, and lined up with the white silkscreen line on the left. Now compare to the second picture,the chip is too far to the right and too far up, by over a milimetre or two

                                    No, I haven't. The last time I tried using HPUnlocker, I wasn't successful. I guess I don't know how to use it correctly.
