Hello guys
I managed to updae cpu microcode
next step for the register does not work'
.2) MSR 0xE2 register unlock for OSX Kernel Write
On a real Mac with native OSX XCPM power management, the MSR 0xE2 register is unlocked and therefore writeable. However, on ASUS mobos this register is usually read only. This is also the case for all ASUS X99 mobos. When the kernel tries to write to this locked register, it causes a kernel panic. This panic can happen very early in the boot process, with the result that your system freezes or reboots during the boot process. We can circumvent the MSR 0xE2 register write with a dedicated KernelToPatch entry in the config.plist, namely "xcpm_core_scope_msrs © Pike R. Alpha" and by enabling the "KernelPM" in the config.plist in Section "Kernel and Kext Patches" of the Clover Configurator. See Section E.1) for further details.
However, thanks to CodeRush's Longsoft UEFIPatch distribution and sophisticated MSR 0xE2 Register patches, we are able to successfully patch any ASUS X99 mainboard BIOS distribution and unlock the MSR 0xE2 register. This makes the "xcpm_core_scope_msrs © Pike R. Alpha" KernelToPatch entry obsolete and allows full native read/write MSR 0xE2 register access by the OSX kernel. The patched ASUS mainboard BIOS firmware finally can be uploaded each specific ASUS X99 mainboard by means of the ASUS EZ BIOS Flashback Procedure.
The individual steps for the ASUS X99 BIOS Patching are detailed below:
1.) Download and unzip the
CodeRush's UEFI patch to your Desktop.
2.) To unlock the MSR 0xE2 register for kernel write copy the BIOS firmware file modified in section B.1.1) to the "UEFIPatch_0.3.9_osx" directory on your Desktop.
4.) Open a terminal; type "cd " and drag the "UEFIPatch_0.3.9_osx"-folder on your Desktop into the Terminal window and press "Enter". One can also use the terminal command equivalent:
Code:
cd ~/Desktop/UEFIPatch_0.3.9_osx/
Note that this step is important to successfully execute the UEFI-Patch procedure! You must be in the UEFIPatch directory on your terminal, in order to successfully execute step 5.) below!
Once in the UEFIPatch directory on your terminal, drop the "UEFIPatch"-executable into the terminal window; Also drop the actual BIOS CAP file into the terminal window; Press enter to execute the "UEFIPatch"-procedure.
The equivalent terminal command in case of the ASUS X99-A II BIOS firmware is:
Code:
./UEFIPatch X99A2.CAP
For other mobos, please adapt the adequate BIOS CAP-filename in the command!
During the patch procedure, you will see something like the following message, which can be simply ignored:
Code:
parseImageFile: Aptio capsule signature may become invalid after image modifications
parseSection: section with unknown type 52h
parseFile: non-empty pad-file contents will be destroyed after volume modifications
parseSection: section with unknown type 52h
parseFile: non-empty pad-file contents will be destroyed after volume modifications
patch: replaced 6 bytes at offset F69h 0FBA6C24400F -> 0FBA7424400F
Image patched
6.) You will now find a "***.CAP.patched" BIOS-file in the UEFIPatch folder, which is your patched (MSR 0xE2 unlocked) BIOS file.
wheni run./UEFIPatch X99A2.CAP nothiing happens, except an error
