crimsonredmk, before you contact Pere let me send you a guide to do it. I just figured out how to do it yesterday with Pere's help. It is one thing to have Pere do it but if you ever change your hardware you will need to learn how to do it yourself.

I will post back in a bit, I am loading Windows 7 on my other hard drive right now so once this is complete I will post back.

uofamis, did you get all four cores working, and is your VoodooHDA working?

Yeah, as long as Speedstep is disabled, I can install the VoodooHDA kext and my sound is great. I am going to post a very lengthly Dell Studio 540 Install Tutorial shortly that should help people get this up and going from the begining to the end. Let me know if you have any feedback.

Dell Studio 540 Installation Guide Using iAtkos v7

• In order for this installation guide to work appropriately, you will need to have near similar hardware configurations than what I posted below:

System: Dell Studio 540
Memory: 8GB DDR2_800 DDR SDRAM
CPU Info: Intel® Core™2 Quad CPU Q8200 @ 2.33GHz (7 x 333)
Sound card: Realtek ALC888/1200
Display Adapters: NVIDIA GeForce 9500 GT 1GB PCI-e
Network Adapters: Realtek RTL8168C(P)/8111C(P) Family PCI-E GBE NIC
CD / DVD Drives: D: PLDS DVD+-RW DH-16A6S
USB Controllers: 10 host controllers.
Motherboard: Dell Inc. 0M017G

• Go into the bios and change the Integrated Peripherals from RAID to ATA. Additionally, disable SpeedStep. This is critical, it will not work without doing this.

• Load iAtkos v7 Install Disc.

• When Darwin boot loader screen appears, press F8 rather quickly.

• You will receive a boot prompt, type in the following: -v cpus=1.

• Once the screen below shows up, please read carefully.

• If a hard drive does not appear under the Select a Destination, click on the following: Utilities > Disk Utility. Select a hard drive > click on erase tab > select Volume Format “Mac OS Extended (Journaled) and click erase.

• Now the “Select a Destination” is back and a hard drive should appear. IMPORTANT. You must select Customize. The install disc (iAtkos v7) will have pre-selected drivers. Only install what is listed below for a Studio 540 with the same specs as those noted above:

iAtkos V7 Main System
Chameleon v2
/Extra directory
DSDT
AppleDecrypt
AppleSMBIOS netkas
APIC driver
Disabler
DVI/DVI (nVidia)
Intel SATA/IDE
Voodoo HDA driver
Realtek R1000
Post-Install Actions

Install the Video driver that corresponds to your video card. I had a 1GB Nvidia 9500GT (dual DVI) card and installed the DVI/DVI driver under Nvidia.

9. Once installed you will need to boot off of the hard drive with the OSX. Hit any key once Cameleon starts to load. Until you patch the OS, you will have to boot into the OS each time by using the following commands: cpus=1 –v or you can probably boot using cpus=2 –v as well.

10. Now you should be in the OS. You will need to patch the DSDT.aml file which is hidden under your root drive. To unhide folders/files, go into your root drive and within the search, type in hide. You should be provided with an Application called Show-Hide Files. Click on this to show hidden files.

11. Now you will need to download the DSDT_Patcher. You should be able to find the patcher at the following site: http://uphuck.ggrn.de/forum/viewtopic.php?f=7&t=2987
Within, there is another link to directly download the patcher: http://forum.insanelymac.com/index.php? ... t&id=38192
At the time of this tutorial I used DSDT Patcher 1.0.1e version of the patcher. If you are having trouble finding this file you could probably run a Google search. When you open the DSDT Patcher folder, you should have the following files/folders:
- DSDT Patcher (you will also here this called the Parcher)
- Readme
- Tools
Open up the DSDT Patcher file, a terminal will launch. Next it will say, Press any key to continue. Go ahead and press Enter on your keyboard. Now the last line will state the following: Which OS to Emulate [0=Darwin, 1=WinXP, 2=WinVista]. Go ahead and hit 0 for Darwin and press Enter again.
Now if you go back to the DSDT Folder where the three files were originally located (the DSDT Patcher, Readme and Tools), you will notice two additional files/folders were created:
- Debug
- dsdt.aml
Go ahead and open up the Debug folder, locate a file called dsdt.dsl. Right click on this file and open it with TextEdit (this is an application located within the Applications folder). Once this file is open, locate the Alias CPU section (just run a search and type in the word CPU). For my computer, there were only two results which looked like this:
{
Processor (P001, 0x01, 0x00000810, 0x06) {}
Processor (P002, 0x02, 0x00000000, 0x00) {}
Alias (P002, CPU2)
Processor (P003, 0x03, 0x00000000, 0x00) {}
Processor (P004, 0x04, 0x00000000, 0x00) {}
Alias (P004, CPU4)
}
Go ahead and delete/clean the Alias lines so the end result should look something like this:
{
Processor (P001, 0x01, 0x00000810, 0x06) {}
Processor (P002, 0x02, 0x00000000, 0x00) {}
Processor (P003, 0x03, 0x00000000, 0x00) {}
Processor (P004, 0x04, 0x00000000, 0x00) {}
}
Go ahead and save the file and close it. Now drag and drop the dsdt.dsl file to your desktop, or anywhere else for that matter. Go back to your DSDT Patcher folder, delete the Debug folder and the dsdt.aml file (NOT the dsdt.dsl file you just saved to your desktop).
Double click on your hard drive and go to Applications and find the Terminal (just type in Terminal in the finder if you have having trouble). Before opening the Terminal application, make sure the DSDT Patcher terminal has been closed. Now open the Terminal application. Now drag and drop the DSDT Patcher file which is located within your DSDT Patcher folder in the Terminal. Hit the spacebar and drag and drop the dsdt.dsl file (the one you saved to your desktop) into the Terminal. Now hit Enter, it will not look like much happened and you will be back to a similar terminal window that you saw when you first opened up the DSDT Patcher terminal. It will ask you to Press any key to continue. Go ahead and hit enter and then select 0 for the Darwin OS to emulate and hit enter again. Now if you don’t have any errors you should be good to go. Lets go ahead and open up the new dsdt.aml file which has been created within the DSDT Patcher folder once again in TextEdit. Run a search on the word CPU, you should not find anything. My current version, the unpatched version of the DSDT.aml file which is located (hidden) within the root drive looks like this on the fourth line:
ñ L _PR_[É P001 [É P002 P002CPU2[É P003 [É P004 P004CPU4 DP80

Our new patched file looks like this:
ñ 9_PR_[É P001 [É P002 [É P003 [É P004 DP80
Notice CPU has been removed. Okay, now take the patched version of the dsdt.aml file located within the DSDT Patcher folder and rename it to DSDT.aml. Go to your root drive and delete the DSDT.aml file and drag and drop the new, patched DSDT.aml file.
Now restart your computer, you should not have to enter any commands and it will boot automatically using 4 cores.

uofamis you are the man! I want to make sure your contribution do not go unappreciated. i am new to everything mac and have been discovering a whole new world of frustrations, but am quit proud of how far iv'e gotten in the last 3 weeks with the help of folks like you. my new audio workstation is now complete (as soon as my delta 1010 PCIx replacement card comes). I couldn't be more stoked ive been racking my brain an wallet trying to get my quad core running/stable for over three weeks and with a fresh install combining what has been working for me previously and your guide all my cores are rockin. sports guy if you haven't gotten your machine polished up yet i'd recommend starting with a clean slate and following this guide to the t. Thanks again to all who contribute for no other gain than to benefit the community.

CPU intel Q9550
mobo Gigabyte EP35-DS3L w/ onboard Lan and Audio AL888
RAM 8Gb DDR2 667
Nvidia Gforce 7300GT 256Mb video card
dual boot winXP64/OSX86 all completely working...so far

uofamis22, I love you. :P

All 4 cores working! I remember a while ago BIOSes used to be patched like this and rereleased, this is the same exact thing and it works 100% to the letter. Thanks a million dude.

So I guess that ends my experience with installing Leopard on my Studio 540. Everything works perfectly and 100%. It's been a pleasure working with you guys.

Edit: My Xbench score is 151.14. The hard drive really brought it down (WD Green Power...), but the CPU Test score was 157.91 and thread test was 478.73. Hell yeah. Not bad.

No problem guys, with the help I received at the uphuck forum I was able to take what advice Pere provided and hopefully put it in a format that most people can follow.

I am now trying to dual boot Windows 7 and OSX. Once Windows 7 is installed, I can no longer gain access to OSX. Apparently Windows 7 creates about a 200mb hidden drive that really screws things up and requires tweaking to get this working. I believe there are other forums on this but I haven't taken the time to resolve the problem.

I haven't tested my speeds yet, what program did you use to do this?

Thank you so much uofamis22!! I used your guide and now have all four cores working! I have Q9450 Quad Core CPU and ASUS P5Q-E mobo... Leopard is now fully working One last step is to run Snow Thank you very much and all others on this forum whom post helped me

Writing a Snow Leopard install guide right now. I decided to try out Windows 7 but it's just not right...so I'm writing as I go along. This guide will install the 32-bit, regular ole' mainstream retail Snow Leopard.

You'll need to have 2 hard drives (or 2 partitions, but I haven't messed with that), an exiswting copy of Leopard installed, and obviously a Snow Leo DVD (retail!).

Basically so far...install 10.5 on another HD, one that you won't need anymore (not where you'll install Snow). Format the Snow drive to HFS+, GUID. It has to be GUID.

Boot into 10.5, pop in 10.6 DVD. You can't install from a mounted image file.

In Finder's "Go" menu, click "Go to folder..." and type "/Volumes/SNOWLEODVDNAME/System/Installation/Packages

Open OSInstall.mpkg (not .pkg). Continue to hard drive selection. Choose your formatted, clean Snow drive. Click Customize and UNCHECK ALL PRINTER DRIVERS!!!! IT WILL FAIL UNLESS YOU DO SO. I left only the Base checked. Install. If it fails, reformat and try again, unchecking more Customize options.

Install completes. DO NOT REBOOT YET!!!

You'll need this set of files: http://www.mediafire.com/?zun5nwjyonz

Extract to your 10.5 desktop. Copy over all of those kexts into /Volumes/SNOWLEOHD/System/Lib/Extensions/, chmod 755, and chown root:wheel them. Copy the prefpane somewhere to that volume as well. You'll be double-clicking that once you reboot to install the audio preference pane.

Now, in Terminal, copy over 2 files from your existing 10.5 install to your 10.6 install:

cp -R /DSDT.aml /Volumes/SNOWLEOHD/
cp -R /Library/Preferences/SystemConfiguration/com.apple.Boot.plist /Volumes/SNOWLEOHD/Library/Preferences/SystemConfiguration/

Your EFI Studio settings should carry over to SnowLeopard without a problem. The boot.plist should too, but see the addition you'll need to make at the end of this guide.

FINALLY...update your bootloader.

Install: http://www.insanelymac.com/forum/ind...=post&id=55844

Install that to the SnowLeoHD, not the 10.5 HD you're currently on. It might default to install on the 10.5 drive. In that case, run the installer twice to install on the SnowLeo drive.

sudo reboot. Boot with arch=i386
I recommend adding that to your Boot.plist.

Welcome.

Update to 10.6.1...all updates are safe.

Forgive the crappy quality of this post. It's 12:51AM and I just got done installing Snow Leopard and wrote this as I went along. Ask questions if in doubt.

crimsonredmk ,
Thank you for you wrote that how to install Snow Leopard.

You wrote that instraction next;
You'll need this set of files: http://www.mediafire.com/?zun5nwjyonz

But, it was already Link out...
I can not found that files yet.
What was it? If you know other link. Please help it.

Did you succsess dual boot of Windows7 and Snow Leopard?
