msingh Posted September 14, 2009 Share Posted September 14, 2009 Hello, Getting tired of the repeated issues booting into SL, I decided to go the reverse route. I dug out the SATA HD out, connected it to the USB port using a convertor cable and power supply, and installed SL on it using the guide at: Installation of Snow Leopard Used just the SL installation parts, specifically. I have used a bunch of different discs to try to boot (I have tried cdboot), but I get a kernel panic each time. However, if I follow the remaining instructions (the added kexts etc.) in the link above, I get to a stage that cdboot just leads to the apple wheel spinning and spinning (waited for an hour before losing patience). So, I get a hang. Then I reinstalled - now cdboot just KPs as well. This means that some of the added kexts in S/L/E there prevent the KP but cannot prevent the hang. Can someone with cdboot knowhow (perhaps the author ?) look the link above over and suggest what might be going on ? I have tried both ATA and AHCI modes. Obviously, I want to modify the existing installation of never booted virgin SL as little as possible. I have read that I might have to add the EFI string for my Nvidia Quadro NVS 140M card. I thought Chameleon RC3 (the latest version) could detect this automatically. This laptop has never had any version of OSX installed on it.

riogrande100 Posted September 15, 2009 Share Posted September 15, 2009 I had the same problem, installation goes fine, patched the bootloader, DSDT and kext but soon as it boots Kernel Panic. installation on a dell xps 420 Link to comment Share on other sites More sharing options...
blitaker Posted September 17, 2009 Share Posted September 17, 2009 I had the same issue with my Dell M4300, it would KP when trying to load IOATAFamily.kext. Apparently there is an issue with the kext that is causing the KP. I replaced it with the one attached here and that resolved the issue. Edit: Here is the link to the original post that got me working: http://www.insanelymac.com/forum/index.php?showtopic=186609 IOATAFamily.kext.zip Link to comment Share on other sites More sharing options...

msingh Posted September 17, 2009 Author Share Posted September 17, 2009 I'm using achi mode. Ok. Did you put all the kexts in /Extra or EFI partition, or did you have to move / symlink some to /S/L/E as well ? I would imagine that the particular kext you list might have to be overwritten.

blitaker Posted September 17, 2009 Share Posted September 17, 2009 I tried adding it to the /Extras/Extensions directory but it didn't seem to work, so I put it in /S/L/E and overwrote the existing files. Link to comment Share on other sites More sharing options...
alex romania Posted September 17, 2009 Share Posted September 17, 2009 Did you set the proper permissions after ? flush kext cash and build new mkext's ? This is what usualy works for me when nothing else does Link to comment Share on other sites More sharing options...
msingh Posted September 18, 2009 Author Share Posted September 18, 2009 I tried adding it to the /Extras/Extensions directory but it didn't seem to work, so I put it in /S/L/E and overwrote the existing files. Thanks for that kext. It was not the solution to my immediate problem, but once I got past my initial "Unable to find drivers" problem by adding kexts to /Extra, this fixed the PIIXATA panic. Now I have a different problem - "No HPETs available...CPU(s) configured incorrectly ... AppleIntelCPUPowerManagement/...-90/pmThread.c:148 Upon reading that this is caused by a faulty dsdt.aml, I did the following: 1. Used a Linux Live CD to get dsdt.aml from the laptop (cat /proc/acpi/dsdt > dsdt.aml). 2. Transferred this to the macbook. 3. Disassembled it. 4. Edited it to fix the RTC length 2. 5. Compiled it. 6. Gave me an error that *pnp0c14 had to be purely alphanumeric. 7. Deleted the *. 8. This time it compiled correctly. 9. Copied this dsdt.aml to / and /Extra. I still get the same problem. Am I missing an /Extra kext ? Link to comment Share on other sites More sharing options...
