mikeveli20 Posted January 28, 2009 Share Posted January 28, 2009 I removed my IOPCIFamily.kext from the /System/Library/Extensions folder and before I could install a new one, my power went out and then when it came back and I restarted my computer I got a kernel panic relating to no IOPCIFamily.kext being there. So I booted to the installation DVD (iDeneb 1.3) and opened up a terminal, but I can't seem to figure out how to do anything. I have my replacement IOPCIFamily.kext on my desktop but can't figure out how to move it to my System/Library/Extensions folder or to even access my hard drive for that matter. I tried accessing my hard drive by typing /dev/disk0s2 but it told me Permission Denied. I then tried repairing the permission on /dev/disk0s2 by typing diskutil repairPermissions /dev/disk0s2. The permissions repair seemed to work but I still get the same message when I try to access the drive. Can someone help me get this file to where it needs to go and also let me know if there is a different procedure to install the kext once it's in the proper location since I'm running terminal from the install DVD. Thanks. Link to comment https://www.insanelymac.com/forum/topic/149922-terminal-help/ Share on other sites More sharing options...
Lanceomni Posted January 29, 2009 Share Posted January 29, 2009 Well you can try Single User Mode. Boot using -s Once at the command prompt type: /sbin/mount -uw / You should now be in the root directory of your drive so you can install by doing the following 1. Give yourself root privileges so that you can modify files. I dont think you really need that in single user mode. sudo -s 2. Change directories to your /S/L folder cd /System/Library 3. Copy the kext from your desktop to your extensions folder Replacing MYKEXT with the name of yours. cp -r ~/Desktop/MYKEXT.kext Extensions/MYKEXT.kext 4. Set the proper permissions for the extensions folder. chmod -R 755 Extensions/ 5. Set the proper ownership for the extensions folder. chown -R root:wheel Extensions/ 6. Touch the extensions folder touch Extensions/ 7. Remove the extensions cache to force OSX to rebuild it with our new kext. rm -rf Extensions.mkext 8. Reboot using the boot-flags -v -f -v Verbose Mode displays useful information during the boot process. -f Forces OSX to load kexts from the extensions folder instead of the cache file. We did delete the cache file so this is just a precaution.

mikeveli20 Posted January 29, 2009 Author Share Posted January 29, 2009 Single-User mode when booting from the CD: I booted into single user mode using -s but I can only get as far as cd System/Library. When I type in the next step it tells me, cp: /var/root/Desktop/IOPCIFamily.kext: No such file or directory Also, when in System/Library I typed in "ls" (minus the quotes) to get a directory list and it came up with some directories but the Desktop dir wasn't even listed. Neither was Extensions. Single-User mode when booting from the HDD: Can't even get to anywhere where I can type. There's a bunch of text talking about the missing IOPCIFamily.kext file etc. etc. and then at the bottom it says, Mac OS Version: Not yet set Kernel version: Darwin Kernel Version 9.6.0: Mon Nov 24 17:37:00 PST 2008; root:xnu-1228.9.59~1/RELEASE_I386 Underneath that is a white box and I can't type anything.
