Hi @fabiosun

Everything is working fine on my new rig and I am happy with the performance overall. You told me earlier that you have some experience with patching ASUS motherboard with locked mainboard BIOS MSR 0xE2 register.

Is it possible for you to help me with a patch for my mainboard? As I understand it I could get rid of booth Fake CpuId, PM-patch, xcpm_program_msrs (c) Pike R. Alpha-patch and TSCAdjustReset.kext.

With best regards

obus

The first thing you need to know is what name the file with bios firmware should have, since the file name is always special to motherboard. If you just put the file with firmware as it is - it won't be flashed. And "BIOS Flashback" is the only way to write modified firmware into you bios chip.

Also please note that I'm not responsible for any damage/data loss/whatever. You do it all on your own risk.

So you need to do:

Contact ASUS support and ask them about firmware file name to use with BIOS Flashback. Or try to find it by yourself, but as for me, I wans't succesful and asked ASUS support.
Download the latest firmware for your motherboard.
Use latest UEFIPatch with patches.txt from KGP's guide to patch your firmware. These patches unlock MSR 0xE2 and disable writes to TSR, so you won't need Pike's patch and TSCAdjust.
Grab a USB flash drive which should not be larger than 8 GB. Format it to FAT32 and put a file with patched firmware to flash drive root. Make sure it has the proper name from p.1. I'd also suggest to prepare two flash drives where the second should contain unmodified firmware in order to be able to restore the original firmware if something goes wrong.
Shut down your rig.
Plug the flash drive from p.4 with patched firmware into a special BIOS Flashback USB slot. Refer to your motherboard manual to find it out.
DO NOT POWER UP you rig.
Press and hold BIOS Flashback button until a blue LED starts flashing. Wait until the LED goes off (3-5 min).
Unplug your rig from wall and wait for 1 min. Then open your rig case and press 'CLR_CMOS' button on your motherboard. Refer to your motherboard manual to find out the button and clear bios settings.
Power on your rig and you are done.

The patched bios was installed without no problems

I don't think you actually have this installed.

@obus, I also still don't get why you need FakeCPUID. Your Xeon has the CPUID exactly the same as my Core i9 has, and I never used FakeCPUID. Could you please attach your current EFI folder?

Hi @joedm ru

When I flashed the patched (KGP's) bios earlier today I did exactly as you explain in your guide. I'm sure the bios was flashed correctly but as I said in my earlier post nothing changed. I still have to use my clover patch and FakeCpuid to boot. I tried with and without clover patches and FakeCpuid in several different combinations without success. I attach my config.plist only because I still can't upload a zipped EFI map without getting an upload error even if the file is smaller than 10 mb.

My EFI driver is standard clover 4411 AptioMemoryFix + latest APFS extracted with pacifist from my installation USB. Kext only FakeSMC,Lilu,AppleALC and TSCAdjustReset.

SSDT-XOSI in ACPI Patched folder.

Thats it.

Any ideas?

Ps. I know the flash was lucky because I flashed a new "Welcome to iMacPro logo instead of the ASUS incredible or whatever...d.s

config.plist

You are confusing some aspects related to a patched bios role in your hack
1) with a patched bios as you say to have, have you tested if msr is really unlocked?Simply also checking clover bootlog you can create inside clover configurator

2) you miss another part following guide for X type CPU, your is different

3) check in your actual bios in advanced CPU parameter if you have some part related to CFG config or similar, then also check latest 0502 bios if it has this feature which could unlock some msr for you

and so also if you have an unlocked MSR 0xe2 register you should have the need of a msr program kernel patch to boot (only strangeness is broadwell EP fakecpuid you are using now)
for your information in my X99 Xeon I have to use Always MSR program kernel patch (also with a patched bios) so it could be normal also for you if you have tested well without mixing too many things

Also, we see your cpu acts in a different way from X cpu series , so you can try to use applecpuintelinfo to see some usefull stuff and to understand better.

These tests could be done only by you..and no one has a real experience on your Platform here

Thank's for your answer fabiosun.

I will test a little bit more and contact ASUS Sweden tomorrow and ask if they could provide me with an unlocked bios.

ApplecCpuIntelInfo makes my os crash so it's not an option.

I will come back with more info.

March 25, 2018

@obus

Appleintelcpuinfo can crash also in supported system due very and old reasons

you can do a copy of text like you can see in my pictures here and post what is inside it in particular way take look at

0:100 0:000 BrandString = Intel(R) Xeon(R) CPU E5-2696 v4 @ 2.20GHz
0:100 0:000 The CPU supported turbo
0:100 0:000 MSR 0x35 16002C
0:100 0:000 MSR 0xE2 before patch 00008400
0:100 0:000 MSR 0xE2 is locked, PM patches will be turned on
0:100 0:000 MSR 0xCE 20080C3B_F2811600
0:100 0:000 MSR 0x1B0 00000000
0:100 0:000 FSBFrequency = 100 MHz, DMI FSBFrequency = 100 MHz, Corrected FSBFrequency = 100 MHz

If your bios is patched it will be different

I would like also to advice you to try latest bios (0502) I see it in Asus site

Maybe there in advanced CPU option you can find a way to unlock MSR as I see in new X299 ASUS bios release

You have to read your manual flashback name is inside chapter two in your case

and this is for @obus i think

Also with Broadwell E/EP cpu (E are not Xeon Ep are xeon) different behavior so ie 6900 could not use a fake Cupid and xeon 2696V4 must use
I have tried for @obus a non conventional way because all tries he was doing lead him to a ++++++++

obus · March 25, 2018

@fabiosun.

All this stuff with flashing my bios is not a problem for me. I know all about renaming .CAP file to WSCSE.CAP already flashed a KGP patched bios successfully in terms of FLASHING but in terms of unlocking my mainboard with a NEGATIVE result as I wrote in my earlier post. I know the flashing was working because after the flash I had the new Welcome to iMacPro logo during preboot.

What I need to learn is which patch I need for unlocking just my specific mainboard.

I already tried the new bios 0502 and there is no difference in behaviour and no option in bios to unlock MSR.

This is the text in my bootlog you asked for

what do you mean with a KGP patched bios?

Has he your same system?

When you patch your bios have you a similar output from uefipatch terminal?

by the way if you want to check with yours file..this is a patched file for your MB (0502)

https://we.tl/IzdrZgkF28

use it if you Know what you are doing and obviously at own risk

March 25, 2018

other my question / curiosity is..

which problem do you have with your actual working config?

My friend @fabiosun

None. I just want as little as possible in my EFI folder and in my config.plist. This is sickness since Osmozis time. :whistle:

obus · March 25, 2018

OK @fabiosun

Flashed the patched bios 0502 you provided.

KP after reboot without patch: xcpm_program_msrs (c) Pike R. Alpha and FakeCPUId.

This is really weird. I suspect that the patches.txt file you use either incomplete or invalid. Indeed, try to contact ASUS support and ask them to provide firmware with unlocked 0xE2.

March 25, 2018

@obus

so interferenc patches seem are not good for your bios

tomorrow i will use old patches with your bios if you want to try again

in my opinion also with a patched bios you couldnt avoid to use some patches in config

when you have some time post here images of cpu advanced section and cpu bios section of your bios motherboard

thank you

Thank's @fabiosun

I will test. I have all the time in the world (pension).

I will upload some pics from my bios.

Cheers!

Could you please also provide original ACPI tables? Press F4 when Clover bootloader in on your screen. Then find the tables in Clover/ACPI/origin folder. I've got an idea how to get rid of FakeCPUID for you. If the forum doesn't allow you to attach it, please use any file share service like MediaFire or Dropbox.

Try to drop this table and remove fake cpuid. You don't need any cpu tables for HWP enabled mode. If there is a KP, capture it by your phone or any other camera.

KP after preboot.

Hmm... strictly speaking this is not a KP, but boot.efi got stuck for some reason. OK, so far I'm out of ideas, sorry.

Any comments?

for vega I have no experience, sorry

for bios If you want try this

https://we.tl/DQFh5qSdp2

and see of msr is locked or not

this msr if also unlocked does not solve others "problem

It seems that your patch is working but I still needs "msr-patch" in clover and FakeCPUID.

This time I booted without any patch and CPUID and get KP after preboot.

preboot log is showing patching?
