System/Library/Extensions Doesn't Exist

This is my first install of iDeneb 1.3.

After install, I'm looking at the "No HPETs available" and "Package 0 didn't get an HPET" errors. I've read all over that I should remove the "AppleIntelCPUPowerManagement.kext" file, located in "System/Library/Extensions", but "System/Library/Extensions" does not exist. There is no Extensions folder. "Extensions.mkext" exists, but there is no directory. When I try to remove the Extensions.mkext file, it says that the drive is read-only and I can't delete the file.

Where is the AppleIntelCPUPowerManagement.kext file?

I apologize but I don't quite understand your instructions. When I boot the computer, the Apple logo appears with the rotating icon, and after a while I'm presented with "You need to restart your computer." When I boot the computer using the "-s" flag, I see a console telling me that "Package 0 didn't get an HPET"

When you say "Also check in System Profiler if the AppleIntel - kext is loaded", I don't understand how to view the System Profiler. All I have is a command prompt.

Thanks for the quick reply!

Author Update #2 @Morteo 2009-06-27

Okay, I decided to wipe the drive and start again. This time around there is an Extensions folder, and there's no HPET problem.

Now I have another problem. When I start the system normally it still tells me to restart. When I boot with the -s flag, I'm presented with a lot of "family specific matching fails" errors and a "panic". At this point it shows me a big error and stops working. What should I do now? Would you like a screenshot of the exact error?

Thanks again for all the help.

Field Note #1 @Taisto 2009-06-27

mkext file is just an archive, it contains everything that's used by your system from Extensions folder. You can edit it with this tool :

Mkext Tool (pcwiz computer.com/downloads/MKextTool_1.0.zip)

and see if the kext is there. Also check in System Profiler if the AppleIntel - kext is loaded. If not, the problem is something else. Mkext Tool can also unpack the mkext package for you to recreate the folder with all the kexts.

Field Note #2 @Taisto 2009-06-27

I understand now. I thought you could boot normally.

Ok, so if you want to make any changes on the disk - first, you have to mount the drive. At the prompt write :

mount -uw /

and return. Now you can remove the mkext file, but if you dont have extension folder - it probably wont recreate itself. To unpack the mkext package and see what's inside, or recreate the folder :

mkextunpack -d output_dir file_you_want_to_unpack

hope this will help.
