Everything except my internet and sound work on my PC after i finished installing osx,

i have a Intel BLKDP965LTCK LGA 775 Intel P965 Express ATX Intel Motherboard
North Bridge Intel P965 Express
South Bridge Intel ICH8
LAN Chipset Intel 82566DC

I selected the intel driver for LAN upon install but it didn't work.

Can anyone tell me what kext i need for my Ethernet to work ? Thanks!
