Hi, respectful developers. I am having trouble getting the iPC OSX 10.5.6 Universal Final to work on my computer: HP XW8200

After installing I get the "Still waiting for root device" and instructions said that I need to select a chipset driver while installing in order to solve this. My chipset is Intel E7525 chipset (supports an 800 MHz FSB) but there is no exact driver for exactly this model in the choices. Are there any alternatives that I can pick from the list?

Thank you.

Maybe if you could be so generous and help me to pick the most optimal settings to install Mac?
I also want to add that the os is installed on an IDE hard drive... NOT SATA.
