Thank-you for the effort this works for me!

Basically I did what best could be describe as the "noob" install... I paid very little attention to detail, as it going to become a "Mac" for my 8 year old daughter. When I installed it I just checked every option I thought remotely necessary and it works! I then upgraded to 10.5.5 (actually I installed every update available including the JAVA ones) and it still works (using the AMD updater). So my problem after installing all the software and updating is that it will not shut down properly and just hangs or more commonly has a Kernel panic. Otherwise it is brilliant!

A couple of points:
1. To install it I had to have the BIOS option for a USB enabled keyboard and mouse disabled. (The mouse is USB and the keyboard is PS2)
2. It did not work from the SATA drive but did from the IDE drive

Hardware
AMD 939 x2 4200+
MB GA K8N51GMF-9-RH (latest BIOS)
8500GT (runs two displays)
LAN: Generic card with Realtek 8169 (could not get the onboard to work and could not be bothered trying)
2Gb DDR400
160Gb IDE
200Gb SATA2

Thanks in advance
