Hmmm... very strange. Which FakeSMC do you're using? I am using V 2.5 . Maby this is the key to your SpeedStepping?

I'm using V2.5 too, but did add two SMCKeys (BEMB & MSDS) ... can't remember why ;)
I will try out the original one later this evening ...

Edit: no difference with the original fakesmc (beside OpenHaltRestart, LegacyHDA and JMicronATA in /E/E)

Please excuse the delay, I was on a weekend trip. After your post I've downloaded VoodooMonitor to check my CPU Temps and I was a litle bit surprised about the results. You were absolutley right! Without further DSDT modifications SpeedStep seems not to work properly. This is a screenshot taken before modifying my DSDT ...

Posted Image

The screenshot looks exactly the same like you described your results. After modifying the DSDT it looks a little bit different ;) ...

Posted Image

To verify the results I downloaded CPUCooL and booted into Windows without the modified DSDT ...

Posted Image

As you can see, it looks very similar to the screenshot I made on Mac OS.

Because of PStateChanger was not working on my machine, I searched for the E8400 values on the Internet and used them to do the modifications. So could you please do me a big favor and post your PStateChanger results here? This would be very healpfull to verify the edits. Furthermore it would be great if you could test the DSDT.aml attached below and give me feedback.* But note, this is just the first testversion using "GenericScopePR".

Part 2: Installing Snow Leopard using a retail 10.6 DVD on the GA-E7AUM-DS2H

When I get to this step:

17) Rebuild your Extensions.mkext file running the following commands in a terminal window (thanks to rbonon/zhell):

sudo rm /Extra/Extensions.mkext 
	  sudo kextcache -v 1 -t -l -m /Extra/Extensions.mkext \ 
		 /Extra/Extensions /System/Library/Extensions


Terminal says this:

rm: /Extra/Extensions.mkext: No such file or directory

What did I do wrong?

Seems like the install is working EXCEPT for audio (I have none).

@olegischinski

I made some other edits on the DSDT and the results are looking better ...

Posted Image

Now Frequency, Multiplier and Voltage are changing dynamic depending on CPU load. Could you please test the newer version?

@all
If there are more Core 2 Duo E8400 (C0) users, please feel free to test the new DSDT.aml. To verify if it is working in the right way, please download VoodooMonitor and voodoopstate.v4.zip from this thread and post your result here.

You are getting this message because I suspect that you are don't using a Extensions.mkext. By the way, I 'm not using Extensions.mkext too. :)

Which Bios, DSDT and Leagacy.kext do you are using?

hi e60,

speedstep with your new DSDT is working!

I attached some screenhots:
PStates with VoodooPState.kext by PStateChanger and CPU-i (they shows different proposals)
and Status with CPU-i (normaly both Cores are at 40°C)

Status with your DSDT.

Don't know how exactly these Voltage values has to be, but I think there will be a tolerance.

Which DSDT did you use? The newest one I have uploaded today @ 08:27 PM or the one before? And could you please make a screenshot using VoodooMonitor and voodoopstate.v4? CPU-i is not more up to date.

... using your latest DSDT (8:27)

here are the results from VoodooMonitor (they are the same).

May be this results from our different CPU stepping (mine is E0)? That would mean, that OSX override the P-State givin by your DSDT?

Edit: And an other test - making my own DSDT with the P-State values proposed by the PState-Changer (attached screenshot above). Perhaps you could test this one.
It brings the same values in VoodooMonitor for P-States but the Voltage in Status is lower. (screenshot attached)

Oh man, I totally missed that you're using E0 Stepping whereas I had assumed you were using C0. That would explain your values differing from mine.

By the way, I've taken a look at your DSDT and was a bit puzzled - the values displayed are different from the ones shown in VoodooMonitor. How did you proceed when calculating them? You should throw all of the Powermanagement kexts out of Extra/Extensions and boot with a SpeedStep free DSDT.

... yes, they are - I took the proposal from PState-Changer.
In PState 3 the voltage is lower now (0,972), nearly the same as under win7 (0,992), but hasn't the value of PState-Changer (0,925).
Edit: under win7 PState 0 shows 1,152 vs. 1,180 under OSX (which is the proposed value from VoodooMonitor - the value from PState-Changer (so in my DSDT) is 1,087)

So I assume, OSX takes the correct one?

Thanks for the info. My eyes are bleeding and my head is exploding from reading the "Vanilla Speedstep" thread ;) but I hope to get a litle bit clearer on this whole thing. So lets keep us up to date about the progress. Maby we could make a little collection of different DSDTs with different CPU Steppings. Before I forget I have one last request. Could you please make a screenshot from PState-Changer "in action"? ;)

@shawndoggy
Could you please also post your complite system spects like CPU, additional cards ... ?

- Jon55's patch of Rosisoft's DSDT work into the Gigabyte f3a BIOS and kexts - in post #89 of this thread HERE

@shawndoggy
- have look at my post here
- instead of the DSDT.aml posted there, take the last one by e60. Speedstepping will work, if you have the same CPU - otherwise try out VoodooPstate.kext at first placed in /S/L/E (set ownership and rights!)
- for sound take LegacyHDA.kext (in /E/E), (You must set Output in Systemsettings to intern.)
BTW: with the patched Bootloader you don't need PlatformUUID.kext and the Kernel Flag key in com.apple.boot.plist anymore. But don't forget to set the key GraphicsEnabler to yes in com.apple.boot.plist. At the moment I only have OpenHaltRestart.kext, LegacyHDA.kext, fakesmc.kext in /E/E (and JMicronATA because I'm using two ATA-Drives - smbios.plist is in /E)

rm: /Extra/Extensions.mkext: No such file or directory

rm stands for remove, but there is no mkext if you didn't create one
A mkext is a cache-file, it speeds up the boot process and the creation with kextcache will proof all kernel dependences.

... Before I forget I have one last request. Could you please make a screenshot from PState-Changer "in action"? ;)

... first screenshot here. PStateChanger needs the VoodooPState.kext. You can load and unload it with your new DSDT too. (on the fly without reboot)

Yes, this Vanilla Speedstep thread is really wahnsinn ;-)

Customizing the DSDT for CPU-specific info (including speedstep) should be unnecessary. The upcoming version of Chameleon allows you to load your various ACPI tables including the SSDT tables that give proper info for speed step.

You trade mucking around trying to find the right DSDT with doing the leg-work to dump your ACPI tables using a linux bootCD, but in the end you wind of with a more generic solution.

I Poke around and you'll find a thread by Valv that discusses AnV's chameleon booter. I certainly hope that AsereBLN picks up this work of integrates his work into the Chameleon trunk.

BTW did AsereBLN ever make AdidasPrince's patch part of his standard booter? If not please ask him to.

Too bad this board is unavailable anymore it makes a good Hack. Also if anyone know where the MCP79/7a chipset, which is the GA-E7AUM-DS2H southbridge, dataset can be had, please post, we could fix a lot of things if we knew the offset to the various registers.

Thanks for the advise, I didn't knew that. In that case I deleted the SpeedStep Scopes from DSDT and I will wait patiently for the new release.

No, he didn't, but he is thinking about it. I don't want to reveal too much, but he is working on a completely new bootloader. So let us look forward for his new release.

Part 2: Installing Snow Leopard using a retail 10.6 DVD on the GA-E7AUM-DS2H

Last Updated: 11/17/09


By the way, would you be so kind and please update your Guide to point the people to the new DSDT, Asere's booter and this whole updated stuff here? Your last update is form 11/17/09 and since than a few things happend like there is no need for Jon55's Bios etc. :)



@all
I updated all files needed for SL. You will find a GA-E7AUM-DS2H.zip below, containing AsereBLN 1.1.9 Booter, F4 Bios, smbios.plist (updated to iMac9,1 identifier), com.apple.Boot.plist, DSDT.aml, an edited fakesmc.kext to prevent BEMB and MSDS messages on boot, LegacyHDA.kext and OpenHaltRestart.kext. I would recommand to use the newest DSDT, because there was a little mistake in the RTC section.

- For Bios stettings please take a look on this post

- For installation methods you can check dlach's version on the first post, Maharajamd Guide or use tonymacx86's ##### & AsereBLN 1.1.9 GA-E7AUM-DS2H Installer* located below. Alternatively you can use ##### with Chimera** and / or ##### also provided by tonymacx86. For more informations check tonymacx86's blog and start with "STEP 2: INSTALL MAC OS X". When you reach to the end of "step 2", please install "AsereBLN 1.1.9 GA-E7AUM-DS2H Installer" and have fun or go further and use #####. By the way, if you are unsure how to install the AsereBLN package, check the "how to" inside of the Zip file.

Note! Olegischinski pointed me to a important issue. If you want to use #####, please remove all RAM greater than 2 GB. After installing AsereBLN's booter, you can use all of your RAM.

* AsereBLN 1.1.9 GA-E7AUM-DS2H Installer ist able to boot up Mac OS 10.7 Lion

** Please note that Adidasprince's Chameleon patch is not integrated into Chimera. If you want to use it with our Board, you have to install a discrete Graphic Card or remove all RAM greater than 2 GB.

I will try make a quick Guide on how you have to do this later in the week.


Would love the guide... I'm just a script monkey who followed the script in the first post to a T and I don't have audio. Have to confess ignorance about how most of this stuff works, so if you could pretty please just make it simple for the newbs....

(BTW, running q6600 cpu, 2gb ram, no extra cards)

dang, seems like I've got everything working but audio. Any thoughts on where to start from a troubleshooting perspective or should I just start over with the maharajamd guide? Want to be able to do some light movie editing and without audio it's a deal breaker.

hi shawndoggy,

What is the status of your installation? (BIOS, Bootloader)

Do you have a loudspeaker icon in your menu?
Did you change Output to intern in systemsettings? Where are your loudspeakers/headphone plugged in?

It's a little bit difficult to help you, without further information.
