I can't get this thing to install..?

[ottoman673]

Hey, i got the "iPC OSx 10.5.6 Universal PPF5 Final" DVD and i'm having some issues.

Hardware:
Core 2 Duo E8400 3.0GhZ
ASUS P5Q SE Plus
ATI Radeon HD 4850
2GB G.Skill DDR2 1066 RAM
LG Sata DVD burner
WD 640GB HDD
for the purpose of installation, Seagate 100GB external Sata HDD

etc...

i want to install on a Seagate 100GB external HDD since i dont want to format and make partitions..

I loaded the DVD, set the boot priority to the DVD drive, got the install screen, typed in -v and all i got was a reboot. over and over again.

help?
