      Here is my BIOS and what I assume is ME (32MB for BIOS and 1MB for ME).
      If someone could remove my BIOS password for me so I can reflash it afterwards.
      It's an 8FC8.

      Thanks.

        Search at your motherboard you will find another chip write on it 256 or 128

          thanks for your answer. I'm going to look for this other chip on the board. would you allow me another question? My computer is not turning on, nothing happens and I can't enter the bios either. what file here on the forum can i use to reset the bios without losing my original service tag and my warranty?

            If its under warranty get it repaired .If you start messing with the bios and it doesn`t work you might not be able to get it repaired,if you have broken any warranty seal, and dell will know youve worked on it. The other chips are WSON type, if you`re using a SOP8 clip ? it won`t work and you could cause further damage

                Did you make a backup of the 25q80dvsig chip,did you erase it or try programming to it ? ,it is not the bios chip as already pointed out by lapfix

                  at this moment, this chip is blank. I read it with ch341 and there is no data recorded inside the chip. I remember I deleted it and I didn't back it up.

                  I messed up huh?

                    yes you messed up but don`t worry. There might be a 25q80dvsig 1MB file posted somewhere on the forum, and if there isn`t then just ask the next member who posts a request in this thread if they would kindly post it.What is the marking on the motherboard next to the chip, U? something

                      I understand friend.

                      can you please guide me to repair my bios?

                      I already understand that this chip is not the bios, when I find the bios chip and can I get any bin here on the forum and use it?

                      having the same specs as mine?

                        Is it possible to program my WSON type bios chip withou a socket?

                        Directly on the board?

                        Is there an adapter to not need to unsolder the chip from the board?

                                          Can you help me to unlock this BIOS?

                                          try another file, but now it turns on and off and sends the display test, white, black, red, green, blue, black screen, restarts.
