I will test your modified BIOS sometime later. I have no time to test at the moment.

Thanks for your work.

I can't download that PDF file too.

Modify on original BIOS even cannot boot kaby lake.Not the microcode or ME problem.
I don't have such ability to add kaby and coffee support to skylake BIOS.
Even work on kaby BIOS , I cannot make it boot with CPU more than 8 thread.
So port Z370 BIOS is the easiest I can find.

You're welcome! Did you try, original BIOS mod, with update correct microcode for your CPU, and when clean the ME change the SKU to Z370?
This probably all that's needed for original BIOS mod, many guides don't say change SKU, but many users report SKU change help fix mod

If you did not try that, I will make you BIOS for that later to try too, when you have time of course. You have to test though

So no download the PDF for you either? Well, that's no good, who show you that and say "this verb table" stuff fix the BIOS?

Flashed and it wont boot.I guess the PEI module isn't easy to replace.

I tried original bios mod long time ago. Turst me it won't boot any kaby or coffee CPU by just add mircocode and switch SKU to Z370.

how can i to add kaby lake support to bios
i have clevo laptop p775dm with z170 and i want to play with i7 7700
but clevo didn't release new bios to support kaby lake

---

too hard work, you need manualy rewrite some asm parts in about 15-20 pei&dxe modules in uefi, add new cpuid/logic and etc.

I found it's related to verb table in BIOS, but I can't find these code to modify?
Anybody helps?

look for CRB*** modules, pei smm and dxe variants. in 2014 ami bioses, HDA pins assigned in file CRBLib.c, so this is "verb" table.
in modern bioses it may moved to acpi tables

I searched CRB but find nothing.I will look into ACPI tables.Thanks for your advice.

Thanks for testing BIOS and reporting back, I figured it might not boot. Any mod done to this BIOS may cause non-boot due to the Intel Boot Guard.
Maybe it's only certain modules and that Realtek PEI one was a big hassle so I assumed it would probably fail. Then after several ways doing the insert I was finally able to make UEFITool output match for both your mod BIOS and the BIOS I mod so that gave me hope.

I found "CRB" at - AAC9B0AF-A46A-49D8-8016-9B9DAD2C7F5E > subGUID 39045756-FCA3-49BD-8DAE-C7BAE8389AFF (PE32) = DXEBoardConfigInit
Also at 39045756-FCA3-49BD-8DAE-C7BAE8389AFF > PE32 Module = TCG2DXE

lib.c I can only find references in CryptoPkgTest and RAIDModule (Maybe a TPM module too, but knew it wasn't this) - nothing on easy search using CRBLib.c - will keep digging

I thought maybe I found at DevicePathDXE, still checking but I think not

Thanks for the latest update @Mov AX, 0xDEAD - so don't copy/replace module, only edit sections from one to other, or do you think that still crash BIOS?
I do think this one is Realtek, found references to that yesterday. IS this work needed to be done in assembler, or can it be done in hex only? If assembler, I can't do that so I wont be able to help further on this

@dsanke - can you get the hardware ID's for the realtek controller from device manager - right click onto the Controller > "Properties" > "Details" > "Property" > "HardwareIDs"

maybe this is answer, 4 bytes in sequences 01 x7 yy zz looks like in hex dump
in dump also i see incremental NIDs from 11 (01 17) to 1F(01 F7 )

Thank you Movax, I've noticed these hex pattern in modules long time ago but I don't know what they are.
It works!
Now I get my audio work normally.

Thanks you sir,I've fixed that problem.

did you changed platforminit modules or else ?

So audio is now working @dsanke? That's great if it is, very cool, thanks @Mov AX, 0xDEAD
