Hello there,

Have you tried to install any of newer linux distros on that laptop, like ubuntu? Telling you that cause it would tell you at booting process if there is a BIOS bug at your laptop. Its pretty much usual nowadays at some laptops even at some desktop motherboards. The bios bug means that bios is simply not releasing some of the functions needed by the OS. Some laptops that come with pre-installed Vista have that kind of bug in their bios'. Linux would report it but then skip it and continue with installing process. OSX is definitely not, which leads to immediate system hang.

I am not 100% positive but it seems to me that's the case. So if you tried all the methods and booting options, and you are not even reaching 'waiting for root device', and there are a very few options in BIOS to experiment with, IMHO that laptop can't run OS-X. Of course, this doesnt mean its true, you can still try with some newer Leo distro or search some forums like insanelymac for posts with similar problems.

Take care bud!
