Dear ellnic,

Depends what method you used to install snow leopard. a vanilla install will not work because i5 is not supported but check this out http://tonymacx86.blogspot.com/2009/...ctly-from.html

if it has realtek or soundmax (analog devices) you can easily get the kexts also the LAN card has to be compatible, so it you can find out if you can what LAN device in this laptop. the easiest way to get the airport working is to use an official or compatible card e.g. BCM4321XX (Official Airport Extreme card works on PC and mac) or Atheros 5008 again works on PC and MAC.

Tell me if you confident to take the dive.
Regards,
Ash
