Many people have been having problems installing OS X on their 790GX computers after a quick google search.

My error is during the boot up of the install cd, I get a "Still Waiting For Root Device error".
I have tried using LawlessPPCs mod of Zephyroth's 10.5.3 DVD that is supposed to work with Phenom but to no avail.

Below are my computer's specs, perhaps a developer could take a look and figure out a simple fix:

Biostar TA790GX Motherboard
AMD Phenom 9600+ Black Edition
3 GB WinTec Ram (2x1 DDR2, 2x512 DDR2)
Integrated Graphics (ATI HD Radeon 3300 Graphics connected by HDMI)
24" Asus LCD Monitor
Sony DVD-RW/+RW Drive (PATA)
500 GB Seagate Barracuda (SATA)
80 GB Western Digital Raptor (PATA)

P.S. I can assist a developer/troubleshooter with any questions they might have about this motherboard.
