Quad Core Anyone? - Page 6

Well, I installed this kext for the heck of it: http://www.insanelymac.com/forum/ind...owtopic=132491

Then I rebooted, and it showed up on my whole screen, but all I could get was that light blue screen.
So I think I am going to reinstall it, once again... unless I can get rid of that kext somehow

Yeah, I did get through it and it was due to the VoodooHDA or the SpeedStep. If you installed the exact same drivers that is listed within this forum, then I don't know what the problem is. I was lucky enough to get through it.

I just took a quick look and I did not see what install method or version you are using, but I used iPCOSx86 10.5.6 Uni Final and my quad core works great. Threads was one of my best stats on xbench. I have been up and running for a while and have not done any type of install in a while, but, as I recall, the only time I saw any issue with cpus= was with a patched kernel, ie, not updateable. My updateable install works fine. Check out some of my older posts, see if that helps.

I'm pretty sure most of us are using iAtkos v7

but I can try iPC again. I still have the DVD

So I had to reinstall and kept the voodooHDA kext any my audio is working fine, and I haven't had any kernel panics, either.

Yeah, VoodooHDA sometimes causes kernel panics on boot, but a restart fixes those. They're random for me.

As for everyone trying to figure out the DSDT, rock on. Enabling all 4 cores would be killer. I've seen some modded BIOSes - the point was to remap cores 3 and 4 to another processor, so OS X saw 2 physical processors each with 2 cores.

Hey HappyQuadCore, I've got an iPC 10.5.6 DVD too, what did you check to install? I can't find any combination that works. I'll try it though...

Having installed OS X too many times now, I've fine-tuned the guide I posted earlier a bit, so here it is:

System is obviously a Dell Studio 540, Intel C2Q 2.33GHz, 8GB RAM.

Here's what I did:

Disable SpeedStep and make sure SATA operation is "ATA" in BIOS -- IMPORTANT.
Booted iAtkos v7 DVD with arguments: cpus=1 -f -v
Partitioned 1 huge GUID partition, named Leopard.

Check the following packages (in order):
--iAtkos V7 Main System
--Chameleon v2
--/Extra directory
--DSDT
--AppleDecrypt
--AppleSMBIOS netkas
--APIC driver
--Disabler
--Intel SATA/IDE
--Voodoo HDA driver (see below***)
--Realtek R1000
--Post-Install Actions

ATI Radeon 3450 HD isn't included on the DVD, and since I don't have an NVidia, I can't help ya there. I ended up buying an old GeForce 8600GT and using EFIStudio. The kext for the Radeon 3450 you'll find on the insane site won't work, you'll get a blue screen, same with using EFIStudio or OS X86 Tools to add the string to your Boot.plist.

Install, and in Chameleon on boot of your installed system, use the same parameters, cpus=1 -f -v

You can also try to use cpus=2 -f -v as it sometimes works for me.

Voodoo HDA***: This might sometimes cause a kernel panic on boot. Just reboot. It'll eventually work haha.

-----Todo: ATI Radeon HD 3450
Get all 4 cores working

I'm where you're at. I don't know about the whole speedstep deal, so I'm assuming I didn't do it, and I haven't used -f as a boot flag and have been doing fine.

And for the resolution, I used PCWiz's OSx86 Tools to edit com.apple.Boot.plist, and put in my screen resolution (1920x1080) and when I rebooted, the resolution was 1400x1050. It looks a little better, but it still isn't full screen

So I got a patched DSDT.aml and put it in, and it seems like it would work, but it randomly freezes while loading VooDooHDA Driver. Has anyone ran into this or have any solutions?
