I have an HP Pavillion p6203w that I want install Mac OS X Leopard. I download the iPC_OSx86_10.5.6.iso file from thepiratebay.org and burnt it to a dvd+r. I set my bios to boot from the DVD Drive. I boot to the verbose mode by pressing "F8" while loading and type in " -v". That works. However, it stays stuck in "waiting for root device" and repeats it over and over after a while. I really want to install it. My BIOS doesn't have AHCI, but my DVD Drive and HDD are both SATA. The HDD is on the White slot of the SATA connector and the DVD Drive is on the one next to it (I forget which color it is) I don't have any other things attached to it.
Here are the specs of my computer:

1. AMD Athlon x2 2.7GHZ with these Instructions: MMX(+), 3DNow!(+), SSE(1,2,3,4A), x86-64, AMD-V
2. NVIDIA GeForce 6150SE nForce 430 Integrated (could it be that it's integrated ) with 256MB of Video Memory
3. 500GB SATA HDD
4. DVD+-RW SATA
5. MotherBoard:
Manufacturer: PEGATRON CORPORATION
Model: NARRA5 5.0
Chipset: NVIDIA MCP61
Southbridge: NVIDIA MCP61
LPCIO: Fintek F8000
BIOS:
Brand: Phoenix Technologies , LTD
Version: 5.55
Date: 12/08/2009
6. RAM: DDR2 4096MBytes (4GB) from Micron Technology
7. USB Mouse and Keyboard
8. Windows 7 Ultimate 64-Bit
9. 6 USB Ports- 3 used
10. VGA Monitor- HP vs15c

I only have one other DVD+R disc, so i really don't want to use it unless I have to.

Thanks for your help, I have been trying to do this for over 6 months.
