ATA-Problems

Hello! First of all, I'm from germany, therefore my english is not so good, but I'll give my best

I have successfully installed the LawlessPPC 10.5.4 on my system. Almost everything works fine, instead of my graphics adapter (not so bad) and my dvdrw-drive, connected to the (p)ata-controller (really bad).

Some informations about my system:
Mainboard: MSI K9N Neo-F v2
Chipset: nVidia nForce 520
CPU: AMD Athlon64X2 4000+
RAM: 2GB Dualchannel
GFX: XpertVision GeForce 9600GT 512MB
HDDs: 2x 250GB connected to the SATA-Controller (AHCI mode)
DVD: LG GSA-H54L (i guess) connected to the PATA-Controller (first port, slave - I also tried master)

I've installed MacOSX using this DVD drive. After finishing the installation, the System-Profiler doesn't even find any ata-controller besides my sata-controller.

I've searched the web for a long time, but I couldn't find any reason or solution for this problem. It seems to me, that I'm either the only person who has got this problem, or I am the only person who doesn't know that my controller isn't supported

If anyone could give me some hints or tips that would be great.

Greatings from Germany, thanks to those who made it possible to run OSX on my system and sorry again for my english!

Stefan
