battlmonstr Posted August 12, 2009 Share Posted August 12, 2009 Hello, I'm trying to install Mac OS on my PC with Gigabyte GA-K8N51GMF motherboard, which is based on nForce chipset. It has AMD Sempron 2500 (which supports SSE3), NVIDIA GeForce 6100 integrated video, integrated Realtek AC97 audio, integrated LAN card, 500Mb RAM, SATA HDD and IDE DVD drive. The problem is when I'm booting from DVD it says that it starts loading Darwin, loading system extensions, then the screen becomes black (seems that it tries to change the video mode to graphics mode) and in the next second reboot follows. I've tryed iDeneb 1.3 (10.5.5) with nForce patch (after this guide - http://tgrounds.blogspot.com/2008/10/osx-l...055-on-pc.html) and Zephyroth Leopard-10.5.2-AMD-EFI (after seeing my motherboard here - http://wiki.osx86project.org/wiki/index.php/HCL_10.5.2). Both DVDs produced the same result. With "-v" boot key the last line on the screen is like "Loading HFS+ file [/system/Library/Extensions.mkext]" (no errors and nothing interesting before that line, it's almost at the beginning of the screen, see screenshot), then video mode changes, black screen, reboot. What's the problem? Link to comment https://www.insanelymac.com/forum/topic/179430-black-screen-and-reboot/ Share on other sites More sharing options...
J.B Posted August 18, 2009 Share Posted August 18, 2009 it might be something to do with the fact you have an AMD processor, try looking for more guides about installing OSx86 on an AMD based PC http://www.google.com/search?q=install+hac...;rlz=1I7ADBS_en hope that helps Link to comment https://www.insanelymac.com/forum/topic/179430-black-screen-and-reboot/#findComment-1228970 Share on other sites More sharing options...
battlmonstr Posted August 19, 2009 Author Share Posted August 19, 2009 The first distribution I've tried is iDeneb v1.3 10.5.5, which is a DVD universal for Intel/AMD. The second is called Zephyroth Leopard 10.5.2 for AMD, which should work on my configuration according to the wiki report. Both distributions are said to work on AMD, but both produce the same result. My processor supports SSE2 and SSE3. What should I do? Apply some patches? What patches? Try some boot options? What options? How to diagnose the problem? Does Mac OS ditribution have something like recovery console? Can it be run in text mode? Before I've come to this forum for help, of course I've searched Google for an answer... BTW here's another miserable guy with the same problem on this forum - http://www.insanelymac.com/forum/index.php?showtopic=144491 Link to comment https://www.insanelymac.com/forum/topic/179430-black-screen-and-reboot/#findComment-1229730 Share on other sites More sharing options...
vilpostus Posted August 21, 2009 Share Posted August 21, 2009 I guess it's the kernel selection problem. You should probably try out different kernels. Eg. install them (search the forum for HOWTO) and boot with different kernel flags. I have Intel CPU installed, so do not know which one will be best for you. As for my system I've AnV 1.6 working perfectly. You could try voodoo, ToH or AnV. Just google for them. Once the right kernel is found, don't forget to replace the System.kext in /Systel/Library/Extensiions/ with the one that comes in one package with the new kernel. Or you get USB device insertion problem. Link to comment https://www.insanelymac.com/forum/topic/179430-black-screen-and-reboot/#findComment-1231346 Share on other sites More sharing options...
battlmonstr Posted September 19, 2009 Author Share Posted September 19, 2009 That's not a processor problem, because I've tried distibutions, which should work on AMD. I can add that boot loader reboots before the screen turns black. I've tried iPC with a Voodoo kernel and the result was the same. How to install another kernel? What is /System/Library/Extensions/ ? I don't see it on the DVD. The structure of the DVD image is like this: V:\>dir Volume in drive V is Leopard-10.5.2-AMD-EFI Volume Serial Number is C7A1-5811 Directory of V:\ 16.02.2008 14:53 58 688 BOOT 16.02.2008 14:53 2 048 BOOT.CAT 11.07.2007 14:27 512 BOOT0 11.07.2007 14:27 512 BOOT1H 11.07.2007 14:27 7 168 BOOT1U 11.07.2007 14:27 1 794 BOOTHELP.TXT 16.02.2008 14:53 61 440 CDBOOT 11.07.2007 14:27 512 CHAIN0 8 File(s) 132 674 bytes 0 Dir(s) 0 bytes free And this is iDeneb: D:\>dir Volume in drive D is osx86dvd Volume Serial Number is 734A-28F0 Directory of D:\ 07.08.2008 03:19 19 829 APPLE_LI 07.08.2008 03:19 57 888 BOOT 07.08.2008 03:19 2 048 BOOT.CAT 07.08.2008 03:19 512 BOOT0 07.08.2008 03:19 1 024 BOOT1H 07.08.2008 03:19 7 168 BOOT1U 07.08.2008 03:19 512 BOOT1U0 07.08.2008 03:19 1 794 BOOTHELP.TXT 07.08.2008 03:19 61 440 CDBOOT 07.08.2008 03:19 512 CHAIN0 07.08.2008 03:19 41 752 FDISK 07.08.2008 03:19 2 971 README 12 File(s) 197 450 bytes 0 Dir(s) 0 bytes free Maybe the image is corrupted?
