Need Archive of old Dell XPS 8930 CPU bios .

Many years have past, so I have not yet had luck locating these old Intel CPU bios.
I dont want the new bios as its a barrier to system tweaks I want .

Bios sites I remember from the past no longer exist .
Maybe going back to 2015 - 18 ish .
Any help locating these is appreciated.

The Dell support site still has older versions available....

Thanks. However I receive a notice preventing me from downgrading bios .
saying its not allowed. How do i get around this ?

That was never the case as far as I can recall years ago. Now I need to somehow bypass this message.

It'd be beyond my capabilities. The BIOS update files appear to not contain the .bin (or whatever) file as a discrete entitiy, so that would make using a more flexible DOS based flasher difficult.

I think the BIOS chip is soldered to the motherboard, so unless you're prepared to replace a surface mounted device, that path isn't an option.

We see similar questions on the Dell forums. I don't recall seeing any successful BIOS downgrades.
Keep in mind there is no BIOS recovery if its corrupted. The motherboard is toast.
