I've tried iAtkos v7 and iDeneb v1.3... They both installed properly but after trying to boot for about 10 minutes I would get a Mac symbol with a 'not allowed' cursorbut it would still act like it was loading.. I didn't know how to fix my problem so I tried iDeneb which would give me an error as soon as I tried booting. Here's a picture:

 

Anyone have this same notebook and successfully installed Leopard onto it? Or can anyone point me to or tell me how to do it properly for my machine?

Do I need to get more information on my computer or do I have it all here?

Thanks in advance!
