Ok so just to let you know this hardware works on iDeneb! Using 10.5.6!

Intel® Core(TM)2 Quad CPU Q8200 (ICHX Fixed)
Asus P5KPL-AM
Realtek RTL8139 (Used another 8000 family kext)
ATI Radeon HD 4670 (Thinks it is 256mb but it is really 512mb i selected all ATI HD video drivers for safety)

Thanks for all the people here! They didn't help me but OH WELL! I look forward to using this forum for mac after math. All just trail and error with installing.

Now dual booting
FYI, PEACE!
