Found this nice Mobo: Gigabyte GA-73PVM-S2H
It has NVIDIA GeForce 7100 / nForce 630i Chipset and a RTL 8211B chip (10/100/1000 Mbit)

If someone has experience with these components on Leo, please tell me your results!

Thank You!

for network

try forcedeth.pkg from zephyroth 10.5.2 dvd and edit info.plist in forcedeth.kext after installation
locate strings



and insert 0xYYYY10DE (YYYY=dev_id and you can find it in .inf from win driver or in device manager, for realtek 8211BL YYYY=0450)

after that use
sudo kextload -v /System/Library/Extensions/forcedeth.kext

known problems: to prevent ethernet vs firewire conflict you may need to disable ieee1394 onboard in BIOS

this sollution tested on Gigabyte GA-M56S-S3 (Nforce 560, Realtek HD Audio ALC888, PHY RTL 8211BL), Amd x2 BE-2350, Geforce 7600GS 256MB, 2x1Gb DDR2-800 and Leopard 10.5.2 (Zephyroth 10.5.2 for AMD)

im try to 8029(as)

I do the above, and it detects the ethernet card (Rtl8211) but when I plug it in, it is unable to communicate with my router. Just assigns itself a ip adress that is not from my router, and nothing works...any suggestions?

I've RTL 8211 on GA-M56S-S3 mobo, and i've tried so many forcedeth's

still not have internet connection :-(

Well I have been successful with getting online with verizon's vz access manager software and my blackberry acting as a modem...still no luck with any sort of a NIC
