              I had used the https://github.com/chromebreakerdev/DellBIOSTools script, but it gives me an error, that the Intel signature not found.
              Think i perhaps know why, wanted to read the bios file with my EZP2019 programmer and pushed the wrong button 😣 (AUTO > auto recognize the chip brand and size).

              Corrupt backup, slow the programmer speed to 6Mhz and try again.

                I have read the bios chip again with 6Mhz.

                The first time was wanted to read the chip, I pressed the Auto button. I noticed it was starting to erasing, I removed the USB cable

                  If the file is still corrupt, is there a solution ?
