Joey, Changes are you are installing it with the wrong permissions and so it won't load. Make sure the ownership and permissions match the one you are replacing. See http://developer.apple.com/techpubs/macosx/ReleaseNotes/ KernelExtensions.html for more info. Hope this helps, - Dean On Monday, April 28, 2003, at 08:18 PM, Joey Echeverria wrote: I'm trying to build the IOATAFamily.kext from the source code to replace the one that Darwin uses. I can build the extension on my Mac OSX partition, but when I try to replace the previous extension, Darwin no longer boots. It gets stuck waiting for the root device. Is there anything special that I have to do to get the extension to work? Are there build dependencies? The installation of Darwin I have is the Apple binary 6.02 release. -Joey Joseph G.
