Mac OS X wont install?

[julyjuly47]

I've been trying to install Snow Leopard on a i3-540 and a NVIDIA GeForce GT 210, but when I get to the install it just says that it cant install Mac OS X. I'm using iBoot 3.3.0 and the (non-gray, snow leopard art on the disc) DVD, version 10.6.0. If anyone interested I only used -v for the boot args.

Sorry if this is a noob question, but I couldn't find much online.
