Remove kext using install DVD disc Terminal?

[stealthzx]

Keep having to reload system when trying new kext which causes kernal panic crash.

Unable to startup in safe mode, with usb keyboard plugged in, F8 or shift do not work. Have tried repairing permissions with disk utility. Is there a way to remove the kext (IONetworkingFamily, trying to get ethernet to work) with Terminal? ps Terminal noob, if possible type line required to do so please. I have no external drive to backup to, so am I stuck reinstalling system everytime?

cd /Volumes/partition_name/System/Library/Extensions
mv IONetworkingFamily.kext IONetworkingFamily.kext.bad

or

rm -r /Volumes/partition_name/System/Library/Extensions/IONetworkingFamily.kext

If partition name contains spaces, precede spaces with a \ or put the name between "".

 

Example:

 

/Volumes/Mac\ OS\ X/System/Library/Extensions

 

or

 

/Volumes/"Mac OS X"/System/Library/Extensions

[stealthzx]

cd /Volumes/partition_name/System/Library/Extensions
mv IONetworkingFamily.kext IONetworkingFamily.kext.bad

or

rm -r /Volumes/partition_name/System/Library/Extensions/IONetworkingFamily.kext

If partition name contains spaces, precede spaces with a \ or put the name between "".

 

Example:

 

/Volumes/Mac\ OS\ X/System/Library/Extensions

 

or

 

/Volumes/"Mac OS X"/System/Library/Extensions

 

 

Thank you, will come into use quite a bit for me i think!

ps title should have read install DVD disc, not startup disc.

You can edit topic's title clicking on "edit - full edit" in first post.

 

You can use the "tab" key to auto-complete files and folders names in terminal.

I managed to remove the IONetworkingFamily.kext but realised I need to put the original back in place as kernal panic states cannot find required file.

What line of text would I need to replace the original, located on desktop, to replace it in System/Extensions folder?

 

Is there anywhere that teaches the basics of using terminal?

Terminal commands A-Z: http://ss64.com/osx/index.html

 

man pages: http://www.manpagez.com/man/

 

cd to the desktop, then cp-R the kext to /System/Library/Extensions.

 

The following commands restore permissions and rebuild the extension cache:

sudo -s (type your password)
chown -R root:wheel /System/Library/Extensions
chmod -R go=u-w /System/Library/Extensions
touch /System/Library/Extensions/

 

Copying with cp -pR maintains permissions on a file/folder
