                                    can't find it, then make a new thread..
                                    read the forum rules..

                                          Dell Latitude 7420 BIOS Unlock Gone Wrong
                                          by Jeff'sTech
                                          Hello everyone.

                                          I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make...

                                          Dell Latitude 5400 Chromebook UEFI bios
                                          by jhanra
                                          Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                                          so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                                          in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...
