Problems with ethernet. Please help.

[chip22]

I do it. Installation successful. Leopardul works very well, but I have two problems.

1. Internet access. My network card is Intel Pro/100 VE Network Connection. Although I selected it in Customise my OS does not see it.

2. sound. Audio sound card (SigmaTel 9220).

 

But the big problem is Internet access, not necessarily sound. I downloaded AppleIntel8255x.kext I climbed in / System / Library / Extensions / I made a few lines of command, described as someone on the net, but still not working.

What solutions exist for access to internal?

 

System Configuration:

DualCore Intel Pentium D 930, 3000 MHz

Intel Sorento D945GNT

3 GB RAM

Seagate SATA HDD 250 GB

nVIDIA GeForce 6200 TurboCache

Audio (SigmaTel 9220)

 

Thanks in advance.
