SportsGuy, how do you generate a DSDT.aml file? All 4 cores work? Voodoo HDA is known to hang on boot, no workarounds that I know of. As for the Radeon 3450, I chickened out and got an NVidia 8600GT for $40 on Newegg. Works flawlessly.

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?

uofamis22 · #65 07-12-2009, 03:04 AM

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

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.

uofamis22 · #69 07-12-2009, 07:48 PM

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?

uofamis22 · #70 07-13-2009, 01:05 AM

If anyone can get the ATi Radeon HD 3450 video card working at full capacity please post detailed steps. As noted above, I have the Nvidia 9500 but I would also like to figure out how to get the 3450 card running. I have no idea how to add or remove a kext so it would need to be detailed steps.
