installing 10.5.7 ideneb/iatkos on new asus p5qpl-am motherboard

i went out and bought a new P5QPL-AM Motherboard by asus built on the intel G41/ICH7 chipset. Everything is detected properly (even the internal sata drives! those weren't even detected in the old factory motherboard).

Question being - seeing that everythings detected properly, why is the install freezing/stopping at about 15% while copying files and not going anywhere? is this a setting ishould change in the bios that would change this? ive just upgraded the bios to the latest version prior to posting this post so i havent even tried to see if that would help anything. Is there any patched bioses that i should get that may benefit me and this board to install osx properly? Please help, It's gotta be something simple!

BTW is the snow leopard retail upgrade cd a bootable cd? Please advise!

ANY HELP AT ALL IS APPRECIATED!
