Won't Boot After 10.5.5 update

[jross21]

Last week I finally decided to update from 10.5.4 to 10.5.5 after weeks of hesitation. I thought I followed the right steps but for some reason I ran into the infamous intelpowermanagement problem. Now when I boot it hangs then panics. I can't boot into safe nor single-user mode.

 

I did however back up my extensions before the update but I put them on my desktop thinking I could access then from another computer if need be. Unfortunately I don't have permission to access these folders from my G5(which I plugged my non-bootable hard drive into)....

 

So basically to make a long story short I backed up the extensions folder(post update) onto my G5 and I want to restore it back after I delete the AppleIntelCPUPowerManagement.kext but every time I try this(using OSx86 Tools) it doesn't overwrite the bad extensions folder and I still can't boot. Is there anyway to restore these extensions without the AppleIntelCPUPowerManagement kext? I have the Kalyway 10.5.2 disc if that helps. I really can't afford to reformat the drive - I backed up all my crucial data, but I'd lose a lot of small.

 

Any help is greatly, greatly, greatly appreciated!

 

Thanks

remove the extensions.mkext file from the old drive and remove the PowerManagement kext from the extension folder on the old hdd

Thank you so much, worked perfect. I knew I was missing something.

I didn't use this technique, but the upgrade didn't work for me either.
