Manuel Andres Velez Velez Posted January 6, 2012 Share Posted January 6, 2012 Hi everyone, I tried everything and I can't install Snow Leopard in my laptop! I tried with some distros like iAtkos, iPC etc. In my last try I used Empire Efi for AMD (Legacy Boot) + retail... but i get kernel panics! Usually it stucks in: Unable to find driver for this platform: \"ACPI\".\n"@/Extra/builds/xnu/xnu-1456.1.26/iokit/Kernel/IOPlatformExpert.cpp:1393. I tried with -x cpus=1 busratio=19,20,21 but it don't works! Can anybody help me? Specs: Chipset AMD RS880M AMD Athlon II Dual-Core P320 (2,1 GHz, 1 MB L2 cache) ATI Mobility Radeon™ HD 4250 HP 425 Laptop http://h20000.www2.h...odTypeId=321957 Infinitely thanks!

jakealley26 Posted January 7, 2012 Share Posted January 7, 2012 Take a look at this. http://www.mac-forums.com/forums/os-x-operating-system/181506-kernel-panic-wont-boot-os.html There are two suggestions. One is that ACPI has something to do with power managements. The other one that seemed to work is fiddle with system memory.

PookyMacMan Posted January 7, 2012 Share Posted January 7, 2012 Check out the guide in my signature. That uses the OSx86 ModCD, which is now recommended by Prasys (the creator of EmpireEFI).

Manuel Andres Velez Velez Posted January 7, 2012 Author Share Posted January 7, 2012 Ok, I try with nawcom but this is what I get after "darwin x86 press any key to continue..."... it remains also with -x screencapture: Link to comment https://www.insanelymac.com/forum/topic/274330-cannot-install-on-amd-mobo-hp-425/#findComment-1784059 Share on other sites More sharing options...
PookyMacMan Posted January 7, 2012 Share Posted January 7, 2012 Is this actually a retail DVD or a distro? The ModCD only works with retail discs (bought or downloaded), not any distro (like iAtkos, Hazard etc.) Link to comment https://www.insanelymac.com/forum/topic/274330-cannot-install-on-amd-mobo-hp-425/#findComment-1784082 Share on other sites More sharing options...

PookyMacMan Posted January 7, 2012 Share Posted January 7, 2012 I think you may need a different kernel. I'll look one up and post it here with instructions.

betam4x Posted January 9, 2012 Share Posted January 9, 2012 try doing what it says for modcd. Type rd(0,0)/Extra/legacy_kernel or whatever it says (can't remember off hand). If it still gives you problems, type that again and append -force64 to the end.
