dilnalomo Posted May 23, 2006 Share Posted May 23, 2006 hi, can someone explain to me what's the status on dual booting with dualcore CPUs? what extra step is needed to get dual boot? is there a dual core patch or something?

bofors Posted May 24, 2006 Share Posted May 24, 2006 Dual core chips work just like single core chips on OS X. Nothing extra is required. Link to comment https://www.insanelymac.com/forum/topic/18181-dual-core/#findComment-118615 Share on other sites More sharing options...
dilnalomo Posted May 24, 2006 Author Share Posted May 24, 2006 i read in some threads that people had to diable dual core in bios to get dual boot, what's that about?

Colonel Posted May 24, 2006 Share Posted May 24, 2006 i read in some threads that people had to diable dual core in bios to get dual boot, what's that about? I think that was for AMD only dual core processors. But even with AMD, there have been ways to make both cores work.

dilnalomo Posted May 24, 2006 Author Share Posted May 24, 2006 you can point me to the thread that has the workaround for it? Link to comment https://www.insanelymac.com/forum/topic/18181-dual-core/#findComment-119012 Share on other sites More sharing options...
mega Posted May 24, 2006 Share Posted May 24, 2006 duo core users have to disable one in the bios or osx86 wont work the kernel used in the hacked versions is too old dual core users are fine though sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist <key>Kernel Flags</key> <string>platform=X86PC cpus=1 idlehalt=0 fn=3 -v</string> that fixes it, I install with one cpu disabled, I modify this file, then I can re-enable the other core, that way dual booting into xp is dual, and osx86 is solo core Link to comment https://www.insanelymac.com/forum/topic/18181-dual-core/#findComment-119167 Share on other sites More sharing options...

dilnalomo Posted May 25, 2006 Author Share Posted May 25, 2006 what's the difference between duo core and dual core? Link to comment https://www.insanelymac.com/forum/topic/18181-dual-core/#findComment-119311 Share on other sites More sharing options...
Colonel Posted May 25, 2006 Share Posted May 25, 2006 what's the difference between duo core and dual core? I assume you mean Core Duo? The Core Duo is a mobile dual core processor from Intel.

dilnalomo Posted May 25, 2006 Author Share Posted May 25, 2006 so a desktop pc with dual core cpu works fine, but for laptops core duo needs to be disabled in order to dual boot natively, am i right?

Fl0 Posted May 25, 2006 Share Posted May 25, 2006 I'am using a Acer Travelmate 8200 , it has da Intel Core Duo Processor . installed a patched 10.4.4 and a 10.4.3 without problems. At least not with the processor. And there are not entrys in the boot.info to disable one core, i checked this. So if it is not disabled elsewhere by the patch, it should work ok.

mega Posted May 25, 2006 Share Posted May 25, 2006 correct, the mobile cpu centrinio core duo does not work for most people with osx86 the desktop dual core does work fine for most, including myself, same hard drive, in the desktop works, in the laptop does not, crash on boot with error on the core duo, on 10.4.5 I can boot, but it'll freeze every 10 seconds, it's a known bug with the mobile cpu and the kernel we are stuck using Link to comment https://www.insanelymac.com/forum/topic/18181-dual-core/#findComment-119443 Share on other sites More sharing options...

sambo60 Posted June 13, 2006 Share Posted June 13, 2006 That doesn't make sense. Doesn't the macbook use the coreduo from Intel? Link to comment https://www.insanelymac.com/forum/topic/18181-dual-core/#findComment-129180 Share on other sites More sharing options...
gwprod12 Posted June 13, 2006 Share Posted June 13, 2006 It's true that it's counterintuitive. Same CPU, sameish motherboard. Most likely the APIC controller in the macbook/pro is different in some way that in standard 479 (I think Core Duo uses 479) motherboards.

boo50 Posted June 26, 2006 Share Posted June 26, 2006 just to inform all of you and gwprod12 first. what he is not alone with D805 have problem with dual core. today i SUDDENLY CAUGHT the STUTTER effect. just use my DC client as always and typing ... typing.. and nothing appears.. after 1-2 seconds letters which i typing appear... after that finder start to stuttering... move window... nothing.. wait 1-2 sec and it's apper in any place suddely... after that i have some crashes with VLC... etc.. etc.... i don't have idea why....just work as alway and ooops... start to stutterng... i have disabled one core too.... and now it works fine.. but... i wish to get both cores working... it's not interesting to have a Dual Core CPU and use only one...

rastaman3d Posted June 26, 2006 Share Posted June 26, 2006 Someone knows what kind of motherboard uses the Dell Inspiron 9400? Does it means that the centrino duo processors will never work together with OSX?

drib Posted June 26, 2006 Share Posted June 26, 2006 The Dell Inspiron 9400 works great (Xbench score 75 for the GMA950 T2400 version). But you will not be able to use both cores at the moment.

Dr Wu Posted July 14, 2006 Share Posted July 14, 2006 I have a core duo laptop (using the intel 945 chipset -- same as macbook) and both cores work fine, out of the box. So do I with my FE Vaio .

vinayp Posted July 14, 2006 Share Posted July 14, 2006 So do I with my FE Vaio . So I should be fine heh ? I think you should be fine, but judging from the other responses in this thread, having close-to-macbook specs may not be enough to guarantee that both cores work.

So what dictates if it works or not ? I mean the guy I quoted has the 945 chipset , as do I . So it should work . Unless it some weird juju .
