Hello everyone,

I would like to get Broadwell support on ASRock H81 Pro BTC R2.0 (low-cost board for crypto mining).

Main goal:
- insert BDW microcode (40671h) and HSW microcodes (306C1h to 306C3h)

- update VBIOS EFI GOP for iGPU


I have:
- Haswell: Celeron G1840, Core i5-4440
- Broadwell: Xeon E3-1265L v4 (ordered from Aliexpress, still on the way)

I was insert GPU modules to this pre-modified BIOS, but it doesn't work at all.

Please read this post. I asked this some time ago and to this time the manufacturer needs to add ME FW 9.1. Without it will not work.

So did you or anyone never tested inserting 9.1 yourself on this board, sounds like some might be OK with it?

I didn´t try cause I sold my broadwell cpu before mod was finished.

Anyone that has flash programmer can try this ME swap to test if it's OK or not. I would do this with older regularly compatible CPU and stock BIOS (no other mods done). That way you are only testing ME version change working or not.

Thanks! Now I see. Sadly, from the first reply it may not be possible due to the ME issue.
Do you have flash programmer? If yes, then you can test ME 9.1 insertion (By itself, all other mods aside) to see if it fails or not.

Yes, I have Chinese programmer TL866CS.

I was flash official BIOS 1.40. Then update MEI to 9.0.31.1487 and to 9.1.37.1002 via Intel ME System tools v9.1. r7. Always with same result - board is bricked after flashing modified BIOS. Do you know better option?



Funny response from ASRock support:

Dear Jan,

Thank you for choosing ASRock and contacting us.

For system stable, we suggest referring to CPU QVL to install supported CPU.

Besides, we start Broadwell CPU support in Intel 9-series MB : )

Thank you,
Sincerely,
ASRock TSD

Create BIOS from 1.40 with clean ME from repository following the guide, using 1.40 BIOS as setting source and clean ME 9.1 from repo. You mentioned system tools, what did you use in system tools in the test you mentioned, Flash image tool and the ME Clean guide?
It may not work, as they mentioned on the previously linked threads.

I wonder if now, that 3 years has passed since then, if either @SoniX or @plutomaniac know how to better accomplish this, or if it's still just impossible

What is that image, I see ME 9.1, is that showing what's currently flashed in the board or what's in the BIOS you loaded to flash?

@plutomaniac I think Lost_N_Bios was refering to this post from you in the past.

Plutomaniac - yes, I meant now that three years has past, is there any change for this situation based on what you guys said three years ago in that post linked at #2 [Discussion] UBU Tool related Questions, Reports and Suggestions (107)
Mainly, since it's been three years now, has anyone found new or working method to insert 9.1 when 9.0 was original ME? This mod stuff aside, I was only concerned about the ME change and you guys comments in the above linked post.

@JanCerny - yes, I meant using that guide, but I mentioned that before knowing there was possible issue doing 9 to 9.1 change. Even so, that would be how I would attempt to test that, and do the test by itself with older CPU and no other changes to BIOS regarding this mod, only if you know you can recover

I gotcha now, thanks! I know several bclk related settings can be adjusted within the ME settings, but I'm sure it's much more than that. I don't have a similar system so I can't dig into this
