        if you need a bios, post the model of the motherboard and the original bios of the laptop.

              Thank you very much "SMDFlea" for informing me to use "RCUnlocker"... Never used it before but will surely try & inform you. Is this Unlocker menu driven & easy to understand what to do next?? I will read all the instuctions though.

                Hi all,

                I have succeed to desolder the bios chip, how to read and write bios on this chip as it is different from what I have seen until now.

                I have ezp2019+ and ch341a programmers. What other tool do I need to be able to read and to write on this chip?

                Many thanks

                  you can find more videos in this direction on the net..don't forget to make a copy of the original bios and check it with the HxD program to be ok ..

                      Maybe your programmer doesn't support this chip.

                      Normally the structure of an Intel bios file will look like this.

                          it is not detected because there is no perfect contact between the chip and the adapter ...
                          if you use CH341 A try one of these programs..after reading post the bios ...

                              Don't ask, if there's a broken bios that needs fixing, just upload it.
