I have successfully installed iAtkos v7 on my MSI GX620. Everything is working properly except for the wifi card and sound. According to this url OSx86, everything should work out of the box except for the wireless card. But most of the ktext he mentioned is not there so I guess I need to download it and integrate it to the installer.

Now my plan is to use a retail snow leopard disk and manually patched it for my own needs. The question is... how? Most of the tutorials I found here are for specific hardware. I don't know which part to follow. Can anyone here guide me?

Here is my laptop system specs.
CPU: Intel Core2Duo T7350 2.0GHz
Graphic card Nvidia 9600M GT 512MB DDR3
RAM: 2x2 GB DDR2 800MHz
500GB Toshiba MK255GSX
Optiarc DVD-RW
LAN: Realtek PCIe GBE Famile Controller
Firewire: IEEE 1394 @ 400 MHz
Keyboard/Trackpad: ... I don't know but Apple PS/2 works fine for me.
Sound: Realtek High Definition Audio.. I don't know why it didn't work. What ktext should I use?
Wireless: worst part. Intel Wifi Link 5100 AGN
Bluetooth: Bluetooth RFCOMM
