Need Help>> hardware not installed


1 post in this topic

Recommended Posts

I have a Dell Inspiron 2650 with built in NIC and Audio (AC97), I also have a Linksys wireless PC Card all of which DO NOT WORK.


I would really like to get the built in ethernet working or the wireless pc card; what use is a computer with no network/internet?


The error's I'm receiving are as follows:


The system extension "/system/library/extensions/appleAC97Audio.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.


I also get the same error but for these extensions: AppleAC97AudioIntelICH.kext, ApplePS2Controller.kext, ApplePS2Trackpad.kext, ApplePS2Mouse.kext.


I looked and none of these files exist anywhere.

Also, the NIC is listed as Built-in Ethernet in Network Prefs, but it is grayed out.


What should I do?
