                      It works fine.
                      After many hours i realized that the memmory was faulty.
                      With other ddr5 memoory is fine. Click image for larger version  Name:	Screenshot_20251003-193946_Gallery.jpg Views:	0 Size:	775.5 KB ID:	3738297
                      So the bios was faulty and the memory replaced by the owner after no power at all.
                      Thank you very much "noname2024", both bios are ok.
                      All the best.

                                        I've also included another BIOS file for that motherboard Version 1.10.1 to try if they don't work

                                          Dell Latitude 5530 BIOS Password Removal Attempted but I Broke the Laptop
                                          by TopPop

                                          I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip...

                                          Hello,

                                          1.
                                          Dell Optiplex Micro 7020

                                          Reg Model: D15U

                                          Service Tag: 129LF54
                                          2.
                                          Dell Latitude 7430

                                          Reg Model:

                                          Service Tag: 8L0LG94


                                          I have 2 computers with admin password on BIOS. Standard code generators don't work on this new platform.

                                          I have dumped both SPI chips from the motherboard (16MB and 32MB). Could someone please help me remove the password or clean the ME Region?

                                          Attached are the original dumps. Thanks a lot for your help!
                                          ​
