I have to be very surprised because no one noticed that the original BIOS uploaded here is total junk.
The user should first learn to correctly read out and compare a BIOS file.
But now he has already overwritten his BIOS, which is very bad because he no longer has a functioning original.
Everything that was patched is based on its bad original BIOS.
And now they say it doesn't work, now it can't.Comment

Blaze Tech and hoaca388 carried out the patch correctly, it just won't help because the initial BIOS arrived here already damaged.
The patching doesn't check the correctness of the original BIOS file.
I just want to make it clear, not that anyone feels insulted.Attached 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, 😅😅😅... -
