                                      IS THERE THE POSSIBILITY, EVEN IF YOU PAID, FOR YOU TO EDIT A CLEAN FILE DIRECTLY FROM THE SITE? THE NOTEBOOK ONLY HAD A PASSWORD IN THE BIOS, NOW IT DOESN'T TURN ON ANYMORE. I THINK THERE WAS AN ERROR WHEN BACKING UP THE ORIGINAL, I WAITING FOR YOUR RESPONSE SERVICE TAG DQ3F873

                                        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, 😅😅😅...
