Kext 2 should list a dependency on kext 1. When your startup item runs and attempts to load kext 2, the load will block until both kext 1 and kext 2 have loaded.

You'll have to give more information before you can get a meaningful answer. Alternatively, explain why this ordering is important and perhaps we can suggest a way to ensure that it's guaranteed to be correct. Kext 1 is a fake I/O Kit Driver whose purpose is to be loaded as soon as the network stack is available (and even before in theory, though I've never seen it). Kext 1 seats in /System/Library/Extensions and is automatically loaded by the OS. Kext 2 seats in /Library/StartupItems and is loaded through the StartupItems script. On the current OS release (10.4), Kext 1 is alaways loaded before Kext2 so everything is fine. But if, hypothetically, one day in the distant future, there was a major update to the OS, I'm wondering what could happen in such a situation._______________________________________________ Do not post admin requests to the list.
