Dell Sandybridge Mobile QM67: Just a Few Tickboxes Left:

[fspkwonx86]

Theres no Page for Sandybridge... I use a laptop so... : Dell Latitude E6520 nVidia Working.. I can edit this like a OP: Originally was using FakeSMC+Plugins, Now am using VirtualSMC and its working just fine for me..

 

So upon first boot : LocalAPIC Processor = Disabled you need to modify your APIC.aml table and remove the CPUS that macOS isnt using for power management....

and they wont show up as a CPU or that theres one thats Disabled...

 

Quirks Section: There are none, you can-should uncheck all these...

 

Persistent Bug: Mouse Cursor (Previous Selector artifacting the Permanent Cursor) as it moves so its moving as its previously selected Bitmap such as a Text Indicator causing you to click as a text indicator on a button for example and thats wrong its click as an Arrow on the button....

 

AICPM Patch : I have a Issue with _PSS says no Local Variables or Arguments are Initialized but when patching AICPM.kext and Dropping SSDT2,CPU0IST/DMAR/MCFG the system will boot............ It says AppleSMC Cant Initialize the LPC, I used the Device ID of an HM55 i think this is HM57 QM57 for the LPC.... and Changed EC back to ECDV and Changed Device VID to IGPU and PEGP I think to GFX0 and nVidia now works..  thats to fix the Dummy Stubbed Interface Error with just a Bar and the Finder Applets that do nothing with a Black Screen... and Injected EDID....

 

The actual EFI: Clover{Duet,REFIT,OpenCore Library Extensions} - When booting in EFI Mode it keeps trying to Enter Boot-Args... , The Mouse and HFS and Audio Driver Work.....

 

The Model Emulated: uses MacbookPro 8,1..

 

Fixing the DSDT/SSDT Tables: it mainly involves consolidating instructural based asl, with syntaxtual equivalent so a little bit of algebra is required..

 

The Point: to use the least amount of tickboxes..... and have it working at the bare minimum with a how to what for this specific SandyBridge

Board...

 

Fix KEXT Stall Error: NVHDA Stalls.. use AppleALC 1.2.8  or youll be booting for 15 Minutes per restart this ones five seconds....

 

This is the EDID:

EDID: 00ff ffff ffff ff00 30e4 d902 0000 0000 0014 0104 9022 1378 0a15 d59e 5950 9826 0e50 5400 0000 0101 0101 0101 0101 0101 0101 0101 0101 7e36 80b0 7038 1f40 3020 3500 58c2 1000 0018 5424 80b0 7038 1f40 3020 3500 58c2 1000 0018 0000 00fe 004d 4336 4a4e 8131 3536 5746 310a 0000 0000 0000 4131 9e00 0000 0002 010a 2020 0030

 

The ALC_ID=12

 

Fix USB: Inject Device IDS into the Root Controllers...

 

DSDT/SSDT Headers and Normalization: MCFG , DMAR I Assume like DSDT/SSDT2 you have to change it to APPLE Properties..

 

CPU0IST - I do not know how to fix this .... but I drop the table as its required..

 

Fix your RTC and IRQs these you have to do by hand and go ok so if these two conflict here i think its just the LPC and HPET... make it so that none of the IRQs

conflict so that each device has one.......

 

CPUPM Fix: still has to patch the kext, and am still working on getting P/CStates working.. but you have to make a CPU Device List in Scope \ ..... and add PSS CST Methods for each CPU where its calling back to CPU0..... and CPU0 has your Package..... the Values are calculated using ReadWriteEverything from windows you take the Hex Value at High Load and Count it Backwards downwards..

 

I have Updated to the Latest Drivers... High Sierra but as im sure its compatible with newer.. I would like to get this working stable first.. is the hard parts

over its actually booting so..

 

The Last Two Errors before you can call it Stable are the _PSS Error _CST Error _LPC Error i think are an All In One, and that it has a KeyStore Error..

 

I gave the post a nice commemoratory picture that reminds me of the effort i put into my last one of these was

a LONNNNNNNG time ago.. <your_favourite_drum_and_bass></goes_here>
