Jbbrack03 Posted October 24, 2010 Share Posted October 24, 2010 I finally got OSX installed on my work machine. Now I'm trying to install it on my beefier home machine. I get about 10% through the install and I get a kernel panic. Here are my hardware specs: Processor: Intel Core 2 Quad Q6600 2.40 GHz Mobo: Asus P5N-E SLI Chipset: nForce 650i SLI SPP Southbridge: nForce 650i SLI MCP Graphics: Nvidia GeForce 8800 GT (GDDR3 1024 mb) Ethernet: Nvidia nForce Sound Realtek High Definition Audio I'm trying to install iatkos S3 V2 10.6.3 on this system. Under customization, I left the default bootloader checked. I also left all the bootloader options default. Other than that, I just checked the hardware options for the nforce equipment. I also tried changing the bootloader to 32-bit, but that didn't change anything. Can someone that's installed on similar equipment give me some tips? Or if you just have an idea about what might be wrong, I would love some input. Thanks!

be2003 Posted October 24, 2010 Share Posted October 24, 2010 I'm just a newbie too but have you tried using the boot parameter "-v cpus=1"? and did you chose a modified kernel as one of the options?

I tried all the alternate kernels. No luck with that yet. This computer has 4 GB of DDR3 RAM. Can that possibly affect something?

Try booting iATKOS S3 v2 Install DVD with - v arch=i386 cpus=1 maxmem=2048 and follow the iATKOS S3 v2 install guide in my blog........

Thank you for the response. Does this mean that I won't be able to access all 4 cores of my CPU? I was also wondering if it would pick up all 4 GB of RAM...

No, this is just to enable you to install OS X...........from my Snow Leopard Retail Install guide post #1 Furthermore, while slashhack's v0.1 AppleNForceATA.kext (32bit) supports 64bit memory addressing enabling the use of >3GB RAM, some SATA DVDRWs may have problems with this kext......e.g. not being recognized; a SAM Multimedia: Read or Write failed.....error; not being able to burn CDs/DVDs.... So, if this is the case you will need to use MeDevil's AppleNForceATA_Test.kext BUT this kext can only be used with maxmem=3072 in com.apple.Boot.plist or with > 3GB RAM as it does not support 64bit memory addressing.....you may still have issues with not being able to burn CDs/DVDs....... The slashack AppleNForceATA.kext and the AnV variant are in my Snow_Support_Files_V2.3 Quote Link to comment https://www.insanelymac.com/forum/topic/235142-help-with-a-nforce-650i-osx-1063-install-still-need-help/#findComment-1569419 Share on other sites More sharing options...

I'm installing iatkos s3 v2 to put snow leopard on this computer. Is this the best thing to install? Is there a better installer out there that would be more compatible/more stable? Would you recommend using something else? EDIT: Ok here's where I'm at now. I still haven't been successful at getting it to install. I tried this first: -v arch=i386 cpus=1 maxmem=2048 When I did that, a bit list of stuff started scrolling on a black screen. It got to a point where it stopped and kept saying "waiting for root device". It said that about 10 times before I rebooted. I tried again and left out the -v part. This time it started the gray apple screen, but there was a circle with a slash through it above the apple symbol. I waited about 30 minutes and it didn't change. I tried again and just put arch=i386 maxmem=2048. This time I got to the options and hit install. It started installing for about a minute and then went to kernel panic. Any other things that I can try?

Jbbrack03 Posted October 25, 2010 Author Share Posted October 25, 2010 I tried again. This time I used -v -f cpus=1 and it made it all the way through the black screens. It still had a kernel panic after about 5 minutes into the installation. Here is the first part of the panic: panic(cpu 0 caller 0x557e29): "getphysicalsegment () out of 32 GB range 0x1003b000, len 0x1000, class IOGeneralMemoryDescriptor" I'm not sure if that gives any clues as to what might be going wrong. I see that a lot of people are changing their BIOS. Is this something that I need to do for my P5N-E SLI?

Jbbrack03 Posted October 25, 2010 Author Share Posted October 25, 2010 Are you having the same exact problem? Do you have a quad core processor and do you have 4 GB of RAM? I'm thinking about pulling out one of my 2 GB sticks and then trying the install.

I'm thinking about pulling out one of my 2 GB sticks and then trying the install. See post #1 here for Series 6 nForce chipset BIOS settings for OS X............ The kernel panic relates to 32bit versus 64bit memory accessing because you have more than 3GB RAM installed..... So, the system panics with the following message type in the kernel panic log: panic(cpu X caller 0xXXXXXXXX): getPhysicalSegment() out of 32b range 0xXXXXXXXX, len 0xXXXX, class IOGeneralMemoryDescriptor....... AFAIK the reason is that getPhysicalSegment returns a 32 bit address but because the physical memory address cannot fit in 32 bits a panic occurs.....which invariably happens when more than 3GB of RAM is installed on the MOBO..... Hence the need to include maxmem=2048 in your booting instructions..............

It still gives me that error even when I do that. I have two 2 GB sticks of RAM in this machine. If I pull one of the sticks before I do the install, will that fix the issue. And assuming that I do this, will I be able to add the RAM back later and have it all work?

Since maxmem=2048 is not working for you, pull the 2GB RAM module out, then if you install OS X successfully, sort out the AppleNForceATA.kext for > 3GB............

Thank you for all your help. I'll try pulling the RAM and installing again. Now when it says cpus=1, does that make it install with 1 core instead of all 4? Am I going to need to enter these commands to get it to bootup later on? How exactly do I sort out the AppleNForceATA.kext file?

How exactly do I sort out the AppleNForceATA.kext file? cpus=1 enables only 1 core at bootup but if you successfully boot into OS X Installer, install OS X and then boot from OS X on the HDD, then see post #6 above on which AppleNForceATA.kext to install........

I pulled 1 of the sticks of RAM. I didn't use any flags and it installed perfectly. I put the RAM back in and rebooted. It shows up in the system as 4 GB. I didn't have to add or edit anything to get it to work. I really appreciate all your advice. Hopefully this thread will help someone with a similar problem.
