Hello try this file.Comment

Hello, I'm sorry that it didn't work for you, I would like to tell you what I did using the pictures.
In the HxD Editor I added 00FCAA **00 0000 and 00FDAA ** 0000 and replaced the value AA with 00.
I didn't edit your original BIOS file any further.
Now I don't know what the very experienced user (minhdigital) edited.
In comparison, I saw that he does much more.
Only he knows that for sure.
I then always wait until I get into the BIOS after starting it several times with F2, then I insert the service tag and that should be it.
Maybe you'll have better luck with the new file.
Good luckAttached FilesComment

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... -

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, 😅😅😅... -
