Shaneee Posted December 5, 2012 Share Posted December 5, 2012 If you have added the legacy kernel to your USB then boot without the mod cd and type the following, legacy_kernel arch=i386 -force64 -f -v Link to comment Share on other sites More sharing options...
alibabzo Posted December 5, 2012 Author Share Posted December 5, 2012 This time, it seems like all the kexts load, but then I get a blank screen. Nothing but the backlight. Thanks so much for persevering Alistair Link to comment Share on other sites More sharing options...

alibabzo Posted December 5, 2012 Author Share Posted December 5, 2012 The first one gives me the same kernel panic, and the second one gives me the same black screen. Link to comment Share on other sites More sharing options...
Shaneee Posted December 5, 2012 Share Posted December 5, 2012 The first one gives me the same kernel panic, and the second one gives me the same black screen. Ok boot with the following, legacy_kernel arch=i386 -force64 -s and when you can type the following line by line, mount -uw / cd System/Library/Extensions mkdir IntelBack mv AppleIntelHD* IntelBack/ mv AppleIntelSNB* IntelBack/ exit Thanks to treyhamilton25 if that works.

alibabzo Posted December 6, 2012 Author Share Posted December 6, 2012 Ok boot with the following, legacy_kernel arch=i386 -force64 -s and when you can type the following line by line, When I boot with that there's no 'typing interface', just a blank screen that appears for 2 secs or so, then the computer reboots.

alibabzo Posted December 9, 2012 Author Share Posted December 9, 2012 Any suggestions, anyone? Should I open a new topic? I'm not too sure of the etiquette... has this thread strayed too far from the original question? Link to comment Share on other sites More sharing options...

alibabzo Posted December 9, 2012 Author Share Posted December 9, 2012 No kexts with filenames relating to 'NVidia' or 'GForce' or 'nvdresman' in S/L/E, but there is an 'NVSMU.kext'. There's a 'NVEnabler64.kext' in Extra/Extensions...? Link to comment Share on other sites More sharing options...

alibabzo Posted December 15, 2012 Author Share Posted December 15, 2012 Any thoughts, anyone? I've now tried all the kernels included with Chameleon. Some reboot the computer, some kernel panic with ElliottForceLegacyRTC, but none work. I've changed around drivers, temporarily removed Extensions.mkext from /Extras... I'm at a bit of a loose end... please! Alistair Link to comment Share on other sites More sharing options...
alibabzo Posted December 18, 2012 Author Share Posted December 18, 2012 I'm in the process of attempting to patch my RTC in my DSDT. If this doesn't work I can always try the Tonycopypastex86 method I suppose Link to comment Share on other sites More sharing options...
alibabzo Posted December 19, 2012 Author Share Posted December 19, 2012 No KPs to do with RTC now. Hooray! Not all good news though. Now, I have a panic to do with AppleACPIPlatform: Any help would be greatly appreciated. Link to comment Share on other sites More sharing options...

alibabzo Posted December 20, 2012 Author Share Posted December 20, 2012 With boot flags -v -f, I get this: I'm running Chameleon 2.2, so surely there's no need for an update (if there is one)? Is there any way to force a clock speed if it can't find it itself? do I need to do something with NullCPUPowerManagement? Link to comment Share on other sites More sharing options...
Shaneee Posted December 20, 2012 Share Posted December 20, 2012 What kernel are you using? Link to comment Share on other sites More sharing options...
alibabzo Posted December 20, 2012 Author Share Posted December 20, 2012 The 'mach_kernel'. With the legacy kernel and boot flags -v -f I get the same thing. Link to comment Share on other sites More sharing options...
Shaneee Posted December 20, 2012 Share Posted December 20, 2012 Try with this kernel, mach_kernel.zip Boot with the following, mach_kernel arch=i386 -force64 cpus=1 -f -v Link to comment Share on other sites More sharing options...
