Hi @hoeman , yes you can.
I will be putting out a [guide] shortly.
Simply use UBU (i used the v1.69.6) to update attached files. (VBIOS, GOP and microcode)

Just run UBU.bat - it provides fine interface.
starters guide can be found here: [Tool Guide+News] "UEFI BIOS Updater" (UBU)

Do you think this will be harder to work for Zx70 Boards?
PCIe x16 will probably be configured differently due to 8x+8x option?
Would be interesting if it is possible to mod the hexa-core ones to work on the Z170 and Z270 boards.

1) I am planning to test this but it will probably take me a month to collect the HW for testing.
Will post results.

2) Zx70 boards should work just fine as well, because the configuration is done as a configuration of pcie-bridges on board and if the main x16 works, they should too. @dsanke even shared a working example of ASRock Z170 Gaming setup.

Sorry, I can't speak English

Hi, thanks for link, good to know that there are other people chasing this topic.
@Sebastian-Sigma If you would be able to provide mod BIOS file binary from the ASRock B250 that migh help us too.

Hello for everyone!
Thank you for you work/
I have start 8100 on GIGABITE H110M-DS2.
But have problems with PCI-E+voltage, same same like LittleHill on his MSI.

Please tell me: alot of info about Core i3 8100/8350K, but no info about Core i5 8400/8600, somebody tried this tricks with Core i5 or you tried only with Core i3? What about ASRock with Core i5?
I have Core i5 8400 but he didn't start (switchON per 2-3 sec and after switchOFF without any signal)

On Baidu there are only pictures of Asrock MB running with functional PCIE x16 slot.

For i5 and i7 you need to integrate other microcode. 906EA needs to be integrated, i3 has different CPUID.

Give me link to this pictures please.
Believe me, I know everything about CPUID and have tried with mc 06EA (latest revision).
I think all problems in ME, because with ME v11.8 I can't start Core i3 8100 too. Same same problem like with Core i5 - start per 2-3 sec and stop. But if rollback ME in this version of BIOS to v11.6 Core i3 8100 works fine.
So, as I think it's need to fix ME for coffee lake support on <3XX chipsets.

hi @mammoht
The baidu-sources posted by @Sebastian-Sigma shows 12 threads in os,
Even through the pictures are shitty low-res i believe it implies use of i7-8xxx on mentioned board. (also asrock:: ASRock B250M Pro4)

I will try to run i5 at least when i will be able to get the pcie working on something else then asrock.

I believe it can be done purely by bios mode because we have multiple unrelated asrock board tested and they work as a charm, what are the others manufacturers bioses missing ?
As this is a question of PCIe from CPU, layout and periferies on PCH should not affect this.

Best regards so far, will post if any porgress is made.

Need version of ME that used with b250M Pro from baidu-sources...

P.S. I think it was fake with 8700 on baidu-sources... cause picture is very bad quality (nokia 3310?)

I was able to force ME region from working ASRock to same PCH MSI/ASUS boards, no change, did not solve the PCI-e issue so far.
@mammoht: if you have a working example of board from other manufacturer then ASRock and with working CPU-PCI-e lanes please share the bios file or at least a method to replicate results.
Thanks

I do not know English, this short story is from Google Translate!
According to your method to add CPU microcode, VBIOS, GOP; can make most of the H110 \ b150 \ B250 \ h170 \ H270 \ z170 \ z270 motherboard lit into the system. ASRock most models set motherboard, voltage, full load frequency, PCIEX16 can be normal! Asus, MSI, Gigabyte are the first PCIEX16 can not work, and some models of voltage anomalies, if there are voltage adjustment options you can adjust does not affect the use. Also tested a number of small factory motherboard: such as Rainbow, Onda, Ming speed, MAXSUN, Somerset and other brands H110 motherboard, there is a problem, CPU frequency can not work full frequency; such as i3 8100 clocked at 3.6GHz, but these small factories Motherboard can only work at 2.7GHz, I tried to replace the ME version, turn off energy and power constraints, doubu

Success in the MSI Z270 motherboard lit 8700K!

Success in the MSI Z270 motherboard lit 8700K! This is really very happy it!

Its GREAT!
Can you tell what GUIDS in BIOS you have change to start this MB with 8700K?
Can you share your bios?
