[piepolitb]

Hi to everyone!
I am almost new to this MAC-AMD-INTEL-x86-etc-thing
I get my AMD pc working with zephyroth 10.5.2, but without audio, usb and ethernet support

All of this stuff is on my motherboard and the only kext choosed during the installation was the SB chipset... what am I supposed to do to get everything working?

this is my configuration
mb asus a8v e se
chipset via k8t800 Pro
amd athlon 64 3200
ram 2 gb
nvidia geforce2 mx/mx 400
ethernet card: marvell semiconductor yukon 88e8001 (mb integrated)
audio card mother board integrated

thanks!
