Kakewalk: Minimal effort install (EP45, EX58, P55, G41)

[trwoolley]

What is your idle temp (in Celcius, please).

What is your mother board and your Microprocessor?

In my case I have EX58-UD5 + i7 and I have an idle temp of: Core A: 44 Celcius, Core B: 44 Celsius, Core C: 39 Celcius, Core D: 39 Celsius.

Working with ProTools LE in a simple session w/ QuickTime image I can get 51 Celcius in Core A and Core B.

 

I done all as I could to try to lower the temp, flash the BIOS with the last one, replace nullpowermanagement,kext with the last one that CooSee gently linked us in message #1722.

But unfortunately temps remain equal.

 

I was asking to several insanelymac members about their temps (with EX58 mobo + i7) and it is my feeling that this hi temps is normal for this kind of hardware.

 

Hi pepechuelo,

 

I am now using the Extra folder from Swhay's post here:

 

http://www.insanelymac.com/forum/index.php...t&p=1417744

 

It has reduced my idle temps to around 37-40 Celcius. But the included DSDT file is specific for EX58-UD5 only. Nothing left in the E/E folder except FakeSMC.kext. Everything does indeed work!

Hi Trwoolley,

Nice to read from you.

 

So, you just download the extra folder that Swhay posted and you replaced your Extra folder with the Swhay one.

Just that?

No Terminal?

Just drag the original Extra folder that is the Hard Disk to the desktop, for instance, and drag the Swhay one in the Hard disk. Just that?

And may be, correct permissions. yes.

Yes, that is exactly what I did. To be certain it went smoothly I first logged into root before dragging the original Extra folder to a safe storage location and then dragged Swhay's Extra folder into my root level hard drive with Snow Leopard. I didn't touch the boot file. Then I opened Disk Utility, did a get info on my SL hard drive volume, copied the Unique Universal Indentifier (SMUUID), and copied that into Swhay's smbios.plist in his extra folder. You can do that with text edit, then save. Then I just restarted, which logs me back as user instead of root. Very easy!

Thanks trwoolley,

Now it is very late here in my country and tomorrow I have a busy agenda. But as soon as I can I will follow your steps.

Thanks again. I will let you now my luck.

[phlox55]

Possible to use it on Zotac or anything really small ?

 

Awesome work mrjanek.

 

Have you considered to support a really small mobo. Like Mini-ITX ?

[pepechuelo79]

Hi Trwoolley,

 

No. I tried but no luck.

I believe I followed your instructions but:

1st, didn't appeared the green chameleon in boot up.

2nd, during the rest of the process of boot up, the modern grey apple crossed by a light curve line was replaced by a solid grey apple (without any light line). So, no grey apple crossed by a light curve line. Just the solid grey apple.

3rd, After that both screens (I have two monitors connected to Geforce GTX 260 graphic card) became black. Leds into both displays indicated me that no video signal was going to those displays.

 

So I restarted, and using a trick that you taught me, pressing F12 I could reboot from my back up disk (that is a carbon copy cloned from the main one). From there I'm writing now.

 

Given that description, what did I miss? How could I solve my problem?

Thanks a lot, trwoolley

 

EDIT!!!!

Trying to return things to previous stage and having booted from my backup disk, I moved the original Extra folder into the bootup disk and moved to a safe place the Swhay's Extra folder. So, everything should be equal to yesterday. No?

Rebooted but now, F12 and selected my main disk. Suddenly temps look 5 o 7 degrees coolest!

I don't know why now everything is running cooler. My extra folder is the same than yesterday.

I made two snapshots testifying this success.

 

This is my iStat Menu running Geekbench

 

And this is my iStat Menu when idle

 

This idle figures were previously a dream for me.

 

Regarding the figures I get with Geekbench are more or less the same than yesterday.

I will stop here for a time the tuning of this beautifull hackintosh.

May be, could be a good idea mrjanek try to add this Swhay's Extra folder in a effort to get an even better procedure.

 

Thanks a lot, again, trwoolley

[spidey89]

OMG!!! THANK YOU SO MUCH!!! that sounded {censored} but anyway,this is the easiest way to get a hackintosh I've found! Keep up the good work and I'll donate to you as soon as I get my pay

 

You're a huge life saver! I don't know much about all these stuff about EFI for Hackintosh and this really helped me save lots of cash as well!!

 

I really can't stop thanking you and I have no idea how to thank you enough... Thanks!!!

Pepechuelo -

 

I'm sorry to hear it was not successful for you. Which version of the Kakewalk "boot" file were you using? Mine is Kakewalk v.1.8.1 and I have never seen a green chameleon with any version of Kakewalk bootloader!

 

Also, I have only one video card monitor, you have two monitors. Maybe that is the problem.

 

But then, to the second part of your post - i have no idea why your idle temps were cooler after you restored your first Extra folder! A big mystery! Check your BIOS to make sure nothing was changed.

 

I will look into this further after my second cup of coffee!

 

Pepechuelo -

 

Also, I have always had a solid grey apple, not the apple crossed by a light curve line, with Kakewalk bootloader v1.8.1. Did he change the default Theme in com.apple.Boot.plist I wonder?

 

Or did Swhay make some changes to his Extra folder from the time I downloaded it 10 days ago to when you downloaded it last night? I don't know.

 

And Swhay has an Apple Nvidia GT 120 with one monitor connected - similar to my GeForce 9800GT. He used Kakewalk with Asere bootloader 1.1.8, which is Kakewalk v.1.8.1. Mrjanek changed it to AsereBLN Booter v.1.1.9 in Kakewalk v.2.0. I don't use that version.

trwoolley, you are correct I did not make any changes to the extra folder I uploaded. The changes are minimal anyway and nothing special. The most important part of it is the DSDT.aml file, which is only for GA-EX58-UD5 with F10 BIOS and the 920 i7 processor.

 

The only changes to the DSDT are the fix to use stock apple audio (no extra audio kexts) and a fix for the orange icon fix. All the rest of the DSDT fixes are from d00d's topic (I got the original DSDT from his topic).

[spidey89]

Guys,can I check? Using this method,is it possible to dual boot with Windows 7? Like, with 2 hard disks instead of 2 partitions?

[fobmatik]

i recently picked up the ep45 ud3p with a C2Q q9400. im trying to install via kakewalk. i have not been able to get past the blue screen to continue the setup. i am able to boot verbose mode but after it loads the screen stays blue. i tried 2 retail discs and 1 dmg to DL disc.

 

has anyone had this problem before? my graphic card is evga nvidia gtx 260.

 

 

*UPDATE*

i ended up getting it working. dual booting with win7. thanks!

Hi Trwoolley and Swhay,

I don't know why but after a simple Restart my wonderful low temps vanished. Now I have the same idle 43 Celcius as usual.

Ah! trwoolley, you asked which version of Kakewalk "boot" file I'm using: I'm using GigabyteUSB 1.4. Can't remember which boot file was used in my version.

I don't know how I got 38, 38, 33, 33 Celcius. And why everything went away.

 

Another topic.

 

Into my original Extra folder I have:

 

com.apple.Boot.plist

DSDT.aml

Extensions <-- Folder

Extensions.bak.mkext

Extensions.mkext

smbios.plist

 

And into Extension folder I have:

 

fakesmc.kext

HDAEnabler.kext

IOAHCIBlockStorageInjector.kext

JMicronATA.kext

LegacyHDA.kext

NullCPUPowerManagement.kext

OpenHaltRestart.kext

SleepEnabler.kext

 

But into the Swhay Extra folder I have:

 

com.apple.boot.plist

dsdt.aml

Extensions <-- Folder

Extensions.mkext

smbios.plist

 

And into Extension folder I have:

 

fakesmc.kext

 

As you can see there are many differences. I don't know their importance.

[tanlouis]

Should work just fine!

 

 

When does it crash? In the end of the installation process?

If so, then it should work and you should be able to boot.

 

To everyone:

You can now follow me on twitter if you want (@mrjanek)

If you've got any questions you can ask them there if you prefer.

 

 

Mrjanek, messaged you on Twitter but you didn't reply

 

Anyway, as I mentioned, installation with the P55-UD5 doesn't work. Your new revision has allowed me to actually boot into the installation, install the OS, but it crashes right at the end, stating something about not being able to set the drive bootable. Whatever, doesn't sound too damaging.

 

If you then try to boot into the OS, using either your boot disc, or the partition itself, it just turns itself off....just like how it used to with the old kernel. I've tried several graphics cards to no avail.

 

ALSO, for the EP45-UD3P board, enabling fastboot breaks it (You see Unable to find SMBIOS when booting...and the OS becomes really unstable)

 

fobmatik: Make sure you set your drives to AHCI in the bios (You need to change 2 settings to AHCI mode) and that your HPET (under power management) is set to 64bit.

 

Thanks again mrjanek

Trwoolley,

 

I have updated to the last KakewalkBoot.

After that my green chameleon with a inverted progress bar (from right to left) and my apple crossed by a light curve line has gone. Now, my boot goes straight to the very same solid grey apple that you see in your hackintosh. And after that my both displays are working healthy.

Then I replaced my original Extra folder by Swhay Extra folder y follow your steps related with SMUUID edition into smbios.plist

 

But temps remains in the same hi level. (44 Celcius in idle)

Geekbench has improved a little bit.

 

So, I don't know how to lower the temps. And why, for a few moments, that I documented, got normal temps earlier today.

[trwoolley]

But into the Swhay Extra folder I have:

 

com.apple.boot.plist

dsdt.aml

Extensions <-- Folder

Extensions.mkext

smbios.plist

 

And into Extension folder I have:

 

fakesmc.kext

Ah, Pepechuelo, I don't have an Extensions.mkext in my Extra/Extensions folder, and neither does the one I downloaded from Swhay. Picture below:

 

 

And I don't ever remember Kakewalk installing one either! The Extensions.mkext is usually a compiled combo of many kexts. Did you do that yourself?

 

Anyway, you should remove it and reboot! Then see what happens. Good that you have a bootable clone as backup.

 

P.S. Make sure you have RealtekR1000SL.kext in your System/Library/Extensions folder. That should have been installed with Kakewalk!

Hi Trwoolley,

I removed Extensions.mkext that I guess it was created by Kext Utility.

Repaired permissions.

Now my new idle temp are quite close to my lowest previous figure I got.

 

I believe this is the best I can do here.

Yes I have RealtekR1000SL.kext in my System/Library/Extensions folder.

My Geekbench figure is around 9200. I have not OCed my CPU.

Some times I get 9380, some times I get 9150.

I feel happy.

It's enough.

 

Thanks again trwoolley and Swhay.

I have a upgrade hardware question.

 

Ok I used this Kakewalk method for installing OSX on my machine months ago.

It's been amazing and the best part about it is, it was stupid simple.

 

Hardware I'm currently running:

 

EP45-DS3L

Q9550 CPU

GTX 260 Video card

8 GB DDR2 1066 RAM

 

500 GB system OSX (GUID)/Windows 7 (MBR), Dual boot MBR Hybrid drive (Windows 7 partition active) 250/250

500 GB data drive, 1 GB partition for the EFI boot (I installed the kakewalk boot upgrade on it), the reset of the drive is just data

1 TB Time machine

 

I want to place these drives in another system (basically just upgrading to an i7 setup)

I got all the hardware already (everything laying on the floor ready to go)

 

I got the supported EX58-UD3R board (I do wish the newer X58 boards were supported at this time, but it's not big deal)

 

My question is how would I go about this, I don't want to have to reinstall anything.

I thought it could be as simple as just installing the kakewalk boot upgrade on the drives in question (but this time using the EX58, and not the EP45); then making Windows 7 partition activate again, but something tells me it can't be that simple.

 

Here is what I'm upgrading too:

EX58-UD3R

i7 930

2x GTX 260's

6 GB DDR3 1600 RAM

New Chassis, new Power supply

 

Can anyone helping me with this, if it's to much trouble, I may just take all this stuff back.

 

Looks like no one responded to my questions...

Seems to be happening to me allot these days

 

I found that when I placed my drives in the new system, it booted up into SL no problems, and almost everything worked.

I noticed an issue with fireWire not working, then it started to click, in that I may need to just reformat, and reinstall SL using the EX58-UD3R.

I was pressed even more to go that route, when I found my system drive some how got converted to MBR, when I was trying to get Wmare back online (which never worked)

 

Lucky for me I already reformatted my 8GB jump drive and prepared it for the EX58-UD3R SL install.

 

Well here is my new problem (which should be a easy issue).

 

After the re-installation of SL on this machine, everything worked, sound, video, fireWire...

But my drives don't look like HD's anymore, they look like external yellowish orange drives.

I had a feeling this was going to happen, because even in the installer they looked that way, and I remember when I used kakewalk to install SL on my EP45-DS3L machine, the drives looked normal.

I have seen this issue before, and I thought it had something to do with the SATA controller not displaying correctly, but when I look in system profiler they display as Intel ICH10 AHCI, which I guess is correct.

 

All the issues I have been having with this hardware upgrade, has really depressed me

To spend over 1000 dollars in upgrades just to say "I have a i7 system" doesn't appear to be worth all the headaches and sleepless nights. I keep saying to myself my old machine worked just fine. OSX/Windows 7 dual boot same drive, vmware.

 

I'm sorry to vent on here, but I thought maybe someone on here would understand my pain.

Working on a Hackingtosh setup, with my level of knowledge on the subject, leaves me feeling hopeless at times, and what makes it worse is you know if you had a better understanding, you could get it working.

 

I hope someone can respond to this, with a solution to getting the drives to display as normal HD's again.

Then hopefully I can put all the pieces together to get this machine to be close to what my other one was.

"- Removed IOAHCIBlockStorageInjector.kext from multiple motherboards"

 

Thats the problem....

 

looks like this has been removed from the 2.0 version.

I read that it shouldn't be needed when your DST file is corrected populated matching your SATA controller.

 

This maybe the case, but I feel IOAHCIBlockStorageInjector.kext, may need to be added in version 2.1 (at least for my mobo )

 

Anyway adding the file in question to the Extra's (on my jump drive) resolved the problem.

 

Sorry for coming off so "lame" but a system build not going smoothly, added with a lack of sleep can do that.

 

Currently bring my machine back to life via my Time machine drive.

 

Now time to get some sleep....

[le jean]

Thanks a lot for this great effort!

 

Kakewalk seems to be a very simple method to get sno leopard up and running.

 

unfortunately I have a Gigabyte EP-45-UD3, which is not listet to be compatible in the first post oft this thread.

will this still work? I do want to use the CD/DVD install method (as i dont have a 4gb+ usb stick). Which of the motherboard options is best to try out? (i.e. which is the closest one to my EP-45-UD3)?

[ilanza]

Hi, I have had great succes installing OSX Leopard on i7 in a Gigabyte EX58 UD5, with this install method. But I have had a problem upgarding to 10.6.2 with graphics card ZOTAC GFORCE 9800 GT 512 DD3. No dual monitor DVI since I have upgraded. The rest is ok. I need your advice, on changing the VIDEO card. I have tried several methods to make the card work but none have had succes. So Im thinking on switch the car for onre more compatible. I need advice on this. My needoings are 2 Monitors via dvi or HDMI. And the graphics are for Audio Editing, and video HD watching. No gaming just professional audio, and video.

 

I will accept any advice, but tested ones I prefer. Thanks.

SOLVED, Just update to 10.6.1 And repair permissions. Go to /system/library/extensions and copy NVDANV50Hal.kext NVDAResman.kext. Update to 10.6.2 replace the Kexts with the ones that you have copied from 10.6.1 and restart. Repair permisions ane ITS DONE. Just worked for MY ZOTAC, I dont know if for other brands, But just try it.

Hi ilanza,

 

I have de same mobo. But my graphic card is a GeForce GTX 260. I was just a plug 'n' play. I did nothing in relationship with it.

The back of the card has two DVI sockets. In each one I have connected a DVI to HDMI adapter. From there two 15 meters (45 feets) HDMI cables to my two 23" DELL LCD monitors. They are working at 2048 X 1152 each one. That limit is given by the displays, not by the card. As I understand the card could work till more that 2500 x I don't know.

 

I use this hackintosh as host for a Digidesign's ProTools LE v8.0.3.

 

I recommend this card.

 

Good luck

Use an EFI string for your card in the com.apple.boot.plist in /Extra and set the GraphicsEnabler key to NO. I use a Zotac, dual DVI card (9500 instead of 9800) in a machine with 10.6.2. Both DVIs work using an EFI string.

 

You can use OS86tools to generate the EFI string for your card then copy and paste into boot.plist. Be sure to include the device-propertites key.

Thanks for your quick responses. I will try the everdone solution (as long as him give me more details). But if it didnt work I will Go for a GTX 260 as Pepechuelo says is plugnplay. GRACIAS AMIGOS.
