It uses RTL8169 chip, and supports Mac OS X. Looks like it comes with the driver. Can I just install the original for Leopard 10.5.2 AMD or I have to patch the driver somehow before install it? I tried to installed a driver for my sound card ESI Juli@. I download the OS X driver from its website and install it without problem. But then after reboot I got kernel panic. I wasn't sure if it's gonna work and I just want to experiment. Obviously it doesn't work.

My question is: if I want to install driver for a hardware, what is the correct way to do it for a hackintosh? I probably won't use my ESI sound card but I do need to use this realtek 8169 NIC since my onboard one in nforce, which gives me trouble all the time.

Thanks.
