Here are the steps:
1. Download the ALSA driver package from an FTP site (Google it!!!) and untar it in your home directory.
2. If you really need to configure ALSA for your 3000N100, mail me. I will send you a patch file.
3. Untar the patch file "patch_realtek.c" and replace the same file in the folder "alsa-driver-xxx/alsa-kernel
4. cd to "alsa-driver-xxx" folder.
5. Issue ./configure --with-cards-hda-intel
make
make install
