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.

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.

thanks for the answer and effort, unfortunately, the original bios was loaded incorrectly and now there is a problem, I solved the problem with another bios

Can't find anything at Dell under your service tag DLX8X93? It should look like this.
