I installed SL 10.6 to my Dell Mini 10. (installed on my external usb hdd)

Apparently, the trackpad isn't working, there is no sound and my internal harddrive is not recognized.

Some people who have SL on their Dell Mini 10 had their trackpad working out of the box. SL on Dell Mini 10

I already tried VoodooPS2 and ApplePS2 but those didn't work. I also tried VoodooHDA but it didn't work as well. For the internal hdd, OSX can recognize my internal harddrive only when it is not shut down properly. (When this happens, it boots very slowly... will be stuck at "Waiting for DSMOS..." for around 5-6 minutes... then continues booting)

Any ideas?

I got it to work. I just had to install the kexts in S/L/E.
