I know that there is some embedded hardware on the market with q81 chipset and broadwell cpu. Maybe I can find which manufacturer offered this system and we can get a bios file. And if I remember correctyl there was some ASRock mainboard, offered only on chinese market, that has Broadwell Support at the product page. But this page dissapeared very fast and I never figured out if it was just false advertising or if they did something that intel didn´t like.

I can offer a lot of time to dig into it and will have a z87 board in a few days. But I need more knowlegde or in other words help from other user, maybe more then they are willing to spend.

That would be good starting point, but may only apply to the brand/board you find it for and it's previous model. Maybe the page you mention can be found in google cache?

Even years ago I never found the page a second time.

Only thing I actually found is that some other people tried the mod and failed, even with changed ME. One user suggested to clean the ME but the thread stopped.

BTW: I found a chinese gigabyte product page from b85 board with broadwell support listed, but can´t find the suitable microcode in bios files that are for download.

http://www.gigabyte.cn/Motherboard/GA-B85M-D3H-rev-12#ov

what can't you find in that BIOS oldirdey? I mean, do you need something extracted from the Gigabyte BIOS you linked above? if yes, what, all microcodes? You can do that with MC Extractor
Does that BIOS have 9.1 ME?

There is only Haswell Microcode and older ME in the bios file, I checked all downloadable versions from all revisions. I mentioned a few posts before thats maybe false advertising what I found years ago.

Yes, maybe false advertising, we'd have to have the board to test. So, maybe I have one of those boards in the lab here, I'll dig around and see. Edit, yes I have one!! Not sure Rev. until I find the board though, but it's here in my inventory list so I'm sure I have it.

But, I'm not sure I have a Broadwell CPU, I normally have at least 1-2 cheap CPU's from each socket series, Celeron or pentiums, what model names would those be for Broadwell?

The most common Broadwell are i5 5675c and i7 5775c, but forget to get one cheap. You are lucky enaugh if you can find one.

At the moment I have some MSI H81 Board here but will try to get few more, at least one B85 and Z87 board.

No, I don't have either of those, I'd recognize the name. Is there any Pentium or Celeron ones? I have lots of boards here, but mainly only top end I7 CPU's or bottom end Pentium/Celeron, for this socket I think I have a few i3/i5 I think, and then Pentium/celeron
I'll see if I can find a complete Broadwell list, if I have a CPU then I can test and confirm the above claim to see if it's false advertising or not, if not we can figure out the key!

I found list on wiki, I don't have any of those I only have Haswell/Kaby Lake

Only these 2 desktop cpu are broadwell. Maybe a user that is fluent in chinese language can help us out. There is some mobile to LGA1150 CPU on taobao available. We could ask the seller if they can do the same with broadwell mobile cpu, they are much cheaper then desktop ones.

BTW: Found a MSI board with ME 9.1.3. This board has 4th and 5th gen support on product page. And even the Microde 40671 is installed in bios. Bingo!

Good hunting job! No Asrock H81 to compare with though, MSI build BIOS different so many things will not be same, I would never be able to find correct/all changes.
Do you have flash programmer? If yes, I can make BIOS with that specific ME and specific microcode for the Asrock H81 and you can test (If you can't make BIOS I mean)

Thank you for stopping in and helping us with your great knowledge on BIOS topics @DeathBringer

I will inspect that BIOS and it's modules you mention above that has "Broadwell Compatible" in it's CPU QVL list, maybe I can see how to edit the Asrock BIOS. If it's done in disassembler/assembler I probably can't do it, still learning on being able to decipher stuff there.

@Lost_N_BIOS, try to copy & past by UEFITool :)

I know, that´s why I wrote to ask the seller if they can solder broadwell mobile cpu to it.
