I tried some methods today, but nothing....

Guys, the nForce 570 is a bit of a problem right now. From my experience so far I have never managed to get Lan working on my board. I have an MSI K9N SLI with the nForce 570 MCP chipset that includes dual gigabit lan ports. My only advice is to buy a cheap RTL PCI NIC to save yourselves the time and bother and get surfing quickly.

As for audio, mine has the ALC888 chip which worked out of the box using ACLInject and the ALC888 3 port kext. If you're having issues with the included drivers in the 10.5.2 DVD then I suggest going here and grabbing the attached ALC88x packages which also worked for many others.

Rogue, thank you for the answer!
About the sound, I tried this driver that you told me, but didnt work. I use the ALC883. Any suggestion ?

Thank you!

One question
A network card, with chipset Realtek 8139, works ?

Thank you!

The 8139 'works out of the box' so to speak :)

heheh, great!
I found it for 10dollars :P
I'll buy it and later I post the results....now the only problem is the sound.....=/

Some do and some don't, I tried two different 8139s neither of which worked with any kext.
8169s on the other hand are advertised as being osx compatible check out ebay!

i have another LAN card and my network connectivity isn't a problem right now, but i really need sound. How to fix this problem with this audio device in Leopard 10.5.2 ?

I also have ASUS M2N-E and sound is working. Try adding Azalia 8-port digital during installation.

You won't see the Audio details in the About my mac page, but there is audio. You'll be able to play mp3, etc.

As for the LAN, try this:

I have the same problem on this board

i get audio if I select all audio drivers there on the 10.5.2r2 list

but still no lan
