Thank you SammlerG

I have unlocked many different Bios with Uefipatch tool

My question is different

Is it still mandatory to avoid some kernel panic o system freeze as som time ago or now it is patched in some different ways by boot loader?

I am asking because I have a pretty stable system with a locked or unlocked Bios

 

I think, clover can not unlock a CPU register which is locked by bios.

If msr 0xe2 is locked, no one can write to this. If you do, System reboots with Kernel panic.

You must unlock the register in your bios, see the guides for ASUS X99 and X299.

If your bios is locked, and you don‘t use xcpm patches, then the Kernel xcpm routine writes to msr 0xe2, and this ends with KP.

 

I‘m not sure... maybe clover can patch the kernel code with AICPUPM?

 

Edit: and it‘s not mandatory to use other settings for msr 0xe2.

and this is what i discovered f0r MSR 0xE2... it enable or disable C states of your CPU... 

 

have fun  :)

In my rig it is mandatory to boot

a fakecpuid for Broadwell E or a correspond Broadwell E XCPM patch

 

com.apple.iokit.IOPCIFamily (10.12-10.13::IOPCIConfigurator for X99, (credit Brumbaer)

f 4881fb00 000040

r 4881fb00 000080

and

a kernel patch

xcpm_program_msrs © Pike R. Alpha (I think old reboot fix patch)

f 554889e5 41574156 41554154 53504189d64889fb 85f60f84 84000000 

r c39089e5 41574156 41554154 53504189d64889fb 85f60f84 84000000 

 

and this with nothing else flagged 

And this with or without a MSR 0xE2 Unlocked bios

 

Or with newest clover KernelXCPM feature only flag it and nothing else

 

Asking this because early clover version patched KernelXCPM by default and then this feature was set as optional

 

 

 

If your bios is locked, and you don‘t use xcpm patches, then the Kernel xcpm routine writes to msr 0xe2, and this ends with KP.

I‘m not sure... maybe clover can patch the kernel code with AICPUPM?

Edit: and it‘s not mandatory to use other settings for msr 0xe2.

Now is it clear

If I can ask

Is it possible That new efi driver like Optiofix3 or Aptiofixmemory changed this behavior?

Or it is unrelated?

 

Thank you

 

Both, because the patch does not unlock the reg but prevent writes to it.

E2H 226 MSR_PKG_CST_CONFIG_ CONTROL C-State Configuration Control (R/W)

15 CFG Lock (R/WO) When set, lock bits 15:0 of this register until next reset.

Make macOS great again!

I know that this isn't the right thread but I can't post into UEFI section so please forgive me :D


These Gigabyte guys made a BIOS file that's rubbish to say at least. If I want to unlock secret menus I can't because the program crashes (AMIBCP) if I want to patch it using UEFIPatch says nothing to patch.


What's wrong ?


Here is the BIOS file:


http://download.gigabyte.eu/FileList/BIOS/mb_bios_ga-b85m-d2v_f4.zip


It's a gigabyte board GA-B85M-D2V.

this clover log answer clearly at my previous answer:

 

0:104  0:000  BrandString = Intel® Xeon® CPU E5-2696 v4 @ 2.20GHz

0:104  0:000   The CPU supported turbo
0:104  0:000  MSR 0x35              16002C
0:104  0:000  MSR 0xE2 before patch 00008402
0:104  0:000  MSR 0xE2 is locked, PM patches will be turned on
0:104  0:000  MSR 0xCE              20080C3B_F2811600
0:104  0:000  MSR 0x1B0             00000000
 
My sub sequential question is:
Which PM Patches are automatically turned on by clover for mine Broadwell EP Cpu?

UEFIPatch only patches MSR 0xE2 lock (also known as Cpu CFG Lock) older GA boards afaik do not have this.

does latest clover 4394 installer install properly to 10.13.4? it seems to put it on the root of my "High Sierra" volume now.

 

I have to install to my first partition "Sierra" (shared drive for both os) for it to install to EFI. this issue was corrected a while back in clover. was there a code regression?

Clover installer package has issues with installing into ESP right now for 10.13.4 beta 1. Its a known issue.
