Looking at the log it seems you already have an storage driver (AppleNForceATA) that seems to work for your hardware as it is being loaded but for some reason it isnt finding any devices attached to the secondary controller thats maybe where you have the DVD drive connected to?

Check the device connections to the motherboard ports, so they are connected in the right order and properly jumpered. If that doesnt work you may try using a different connection DVD drive or installing from an USB drive.
