nkear5 Posted March 23, 2008 Share Posted March 23, 2008 Hi, I've recently installed the Kalyway 10.5.1 Leopard disc. Everything was working flawlessly, dualboot via darwin worked perfectly, everything. Then, just yesterday, I needed to use e-sata to transfer some files in vista. However when I tried to boot into OS X, it immediately gave me a kernel panic that was caused by this error. "Unable to find driver for platform "ACPI"". There was more information in the kernel panic, if it is of any importance I will take a screenshot and upload on request. I assumed that this had happened because of e-sata, so I took out the e-sata nic. However the problem still remained. Now the only way to get into OS X is to boot with the -f flag. This is bearable, but an inconvenience. Any help regarding the issue would be wonderful. I did however manage to get it to start without the kernel panic by installing a backup AppleACPIPlatform.kext from the Kalyway Combo Update, and the reinstallation of the netkas kernel (through NVinstaller). However just this morning the problem returned yet again without any provocation. Thank you in advance. :EDIT: Since -f doesn't seem to restrict any usability, I edited com.apple.boot.plist to automatically start with the -f flag. So it completely bypasses the kernel panic without human interaction.

I am facing the same problem as yours since i modded the AppleACPIPlatform.kext in my iatkos 10.5.1 installation.

jakedman Posted August 2, 2008 Share Posted August 2, 2008 Hi, Can you please give step by step instructions on how to boot automatically with -f flag. I am facing the same problem as yours since i modded the AppleACPIPlatform.kext in my iatkos 10.5.1 installation. Read this to learn about editing the com.apple.boot.plist file: http://apple2pc.blogspot.com/2008/02/darwi...ot-options.html or delete your Extensions.mkext file in /System/Library/ to force the system to recreate a new extensions cache. I had the same problem and this solved it. I replaced some kext files but forgot to delete the cache file so OS X was still loading the old ones. Hope this helps. I know this post is old, but I thought I should reply for hope that it might help some lost soul.
