I have been fighting with this the last couple of days. My pc is a Gateway gt5016

Pentium D 820
Intel (Cortez)945G
2 Gig Ram
ATI X800 GTO2

Now my problem arises when I start playing around trying to get my audio to work. When I edit my applehda.kext to try to get the sound to work, it solved another one of my problems. My Ethernet was discovered and connected. A bonus for sure, but leaves me baffled as to how to continue. As soon as I edit that .kext I loose my Ethernet connection. Any help would be greatly appreciated.

Any help with the video card would be appreciated as well.

Thank you
