Checked and tested. Everything is working now. Thank you all very much.
You are amazing !!!!!! magicians

@dsanke - Thank you! BIOS was already working OK with internal graphics, just needed second link BIOS in post #8 fixed for PCIE, maybe HT too not sure (He didn't let me know yet)?
But anyway, yes thank you for jumping in to help!! Can you please Tell me which are the modified modules only for PCIE fix, so I can compare to originals and see how this one is fixed for PCIE - thanks!

* Edit @kruchydik - I see only 8C/8T, do you have HyperThreading Enabled? Sorry, never mind, I see this CPU does not have HT All along I thought it did

@Lost_N_BIOS Si/PlatformInit(PreMem) , total 4 PEI modules for PCIE fix. I modified that BIOS based on the main thread file, you can compare it.

@dsanke - Thanks, so to confirm >>
1. PlatformInitDXE - C5046EFD-7BC3-4206-987C-32DA45026E6D
2. SiInitDXE - ACD28235-075B-48B5-98A1-DA04FCAF84F3
3. SiInitPreMem - A8499E65-A6F6-48B0-96DB-45C266030D83
4. PlatformInitPreMem - EEEE611D-F78F-4FB9-B868-55907F169280

Correct? I appreciate your help on this!! I just want to see how this one is edited for PCIE fix, since patcher did not work and I only found part of the signature it checks for in some modules (but none of the above)

@dsanke I am having the same pcie 16x issue, my mb is Asrock B365M Pro4 and Processor is Xeon E-2246G(U0). I updated microcode, changed the ME to corporate version and disabled ME, I can boot normally but PCIE under CPU not working. I already patch 4 PEI modules in SiInit/PreMem & PlatformInit/PreMem, but still not working. I dont know if I have done it wrongly or something I missed out. I attached the Original bios file and dump mod bios file link here, please help me fix it, thank you.

@evonnewoon I checked the BIOS , looks well. There might a CPU damaged.

Hello, it is possible to unlock all settings on the Z370H4-EM

Especially the one to adjust the power limits of the CPU and OC would be great too
