Network Card should work but dosen't!

Hi,
I posted this in the kexts section but have not got a reply so I thought I'd post it here.

I bought a Realtek RTL8139 Pci Network card which works perfectly in windows.
When I go to install iatkos 7i I select the driver for this card and finish the installation. It then works perfectly for the first boot but as soon as you reboot it reads cable unplugged.

I have disabled onboard lan in the bios.
Any Help Would be Appreciated!!
Have been struggling with it for ages!! :mad:
Thanks

I managed to fix it! I had to use the kalyway distro and if I upgrade past 10.5.4 it stops working. But hey it works!!
So if your having trouble just use the kalyway distro.
