RedNalie Posted January 9, 2010 Share Posted January 9, 2010 LS, I'm having issues installing SL on my P5N-E SLI machine; First some specs: MOBO: P5N-E SLI (nVidia 650i) CPU: E6600 GC: nVidie 9600GT MEM: 1024 DDR2-6400 HD: SATA DVD-RW: IDE (master) According to this website I should use OS X 10.6 Snow Leopard Universal v3.5 and everything should just go fine, except it doesn't. I burned OS X 10.6 Snow Leopard Universal v3.5 to a DVD-R Verbatim Single Layer disc and tried to install, but it reboots everytime after trying to initiate the install gui. I'm not getting any errors, the disc asks me how I want to install and after pressing [Enter] the machine reboots after it says something in the line of "Starting <something>". I tried using [F8] and use several different options such as: -v -x -v cpus=1 -v cpus=1 -x -v -32 -v -32 cpus=1 -v -32 cpus=1 -x -v and I believe some others as well but I get the same result everytime, reboot. No errors or anything, just...reboot. Does anyone have any insight in why this is happening? It's starting to get a little bit frustrating that it doesn't give me any error what soever.

aldmo87 Posted January 10, 2010 Share Posted January 10, 2010 I am having the exact same issue; burned the disc booted from DVD drive types "-v" and hit enter computer reboots process repeats I have also tried booting the DVD in Vmware7 workstation and I get the same outcome The screen displays something along these lines just before it reboots Loading Darwin/x86 loading kernel mach_kernel loading HFS+ file [mach_kernel] from 422f300 loading HFS+ file [mach_kernel] from 422f300 LoadDrivers: Loading from [extra/extensions] LoadDrivers: Loading from [/system/library/extensions.m (missing some text, didnt get all the screen photo) Loading HFS+ file [/system/library/extensions.mkext] from (missing some text, didnt get all the screen photo) Loading HFS+ file [/system/library/extensions.mkext] from (missing some text, didnt get all the screen photo) I found another website that says to try type "cpus=1" as you mentioned before the EFI boots, i'm going to try that now. will post results BTW my system is p5n-e SLI Q6600 8gb DDR2 (x4 2gb sticks) Nvidia GTX 260 Sata harddrive I may also try to update the BIOS, just cant find a BIOS flasher that works in windows 7 x64 Link to comment https://www.insanelymac.com/forum/topic/206442-problems-with-p5n-e-sli-os-x-snow-universal-reboots-on-bootloader/#findComment-1381020 Share on other sites More sharing options...
SquareFeet Posted January 11, 2010 Share Posted January 11, 2010 I found that exact same guide, and tried it also. Same result as you guys. Hardware: P5N-e SLI, Q6600, IDE HDD and DVD, XFX 8800GT. I'm wondering if it could be BIOS settings?

aldmo87 Posted January 11, 2010 Share Posted January 11, 2010 Ive tried many things in the bios but nothing seems to help, anyone know if upgrading to a later version would help (cant flash on x64). All the guides mention AHCI but i've never been able to find anything called that.

RedNalie Posted January 13, 2010 Author Share Posted January 13, 2010 I've already flashed my BIOS to the latest version and doesn't do squat. Isn't there anyone who could provide a solution and/or other (easy) way to install Snow Leopard on this motherboard?

Check that your BIOS settings match those you set when using 10.5.6 2. AFAIK Snow Leopard always expects at least 2 cores to be running, so do not boot with cpus=1 (Glad to be proven wrong on this...... ) So try booting with -v -x32 debug=0x100 and then with -v arch=i386 debug=0x100 if one causes fewer problems than the other, then try in turn -v -x -x3 2 debug=0x100 or -v -x arch=i386 debug=0x100 -v -f -x32 debug=0x100 or -v -f arch=i386 debug=0x100 -v -x -f -x32 debug=0x100 or -v -x -f arch=i386 debug=0x100 and see if debug=0x100 halts at any kernel panics...... It is possible that the cached extensions in Extensions.mkext include a "bad" kext for your MOBO and/or that a "needed" kext for you MOBO is not present.....

2600MHz Posted January 24, 2010 Share Posted January 24, 2010 2. AFAIK Snow Leopard always expects at least 2 cores to be running, so do not boot with cpus=1 (Glad to be proven wrong on this...... ) I don't think that's correct. I remember the early Intel Mac Minis having Solo processors, and I'm quite sure Snow Leopard works on all Intel Macs. Plus it seems SL can be hacked to run on just about any processor anyway Link to comment https://www.insanelymac.com/forum/topic/206442-problems-with-p5n-e-sli-os-x-snow-universal-reboots-on-bootloader/#findComment-1394091 Share on other sites More sharing options...

dannonman Posted April 9, 2010 Share Posted April 9, 2010 I just got Snow Leopard running fine on the P5N-E SLI motherboard (with Q6600 and nVidia 8800GTS). Follow verdant's exquisitely detailed guide (here, once again, if you forgot). I, for example, did parts A, B, C, and D. It's not a trivial task, so be prepared. In short, I put the Chameleon bootloader (I used RC4 and PC_EFI v10.6) and the OS X 10.6 install disk onto a USB drive. Then, I booted to that USB drive to install OS X onto my hard drive. Then, I installed the Chameleon bootloader back onto that hard drive. Then, I could boot to Snow Leopard on the hard drive. Don't forget the kexts and the arch=i386 or -x32 flags. Let me know if you have problems and I'll try to help. I'm not expert, but I have now gotten both Leopard and Snow Leopard working on this motherboard before... so I may remember a thing or two.

Hey man, I got a mobo like that lying around. My next project is to try to get fully working snow leo on it...
