Noob here looking for some help just got a new Toshiba PS305D-S8818 specs. below. I have been trying for a few weeks now to get leopard up and running with no luck. First using leo4allv3 and kept getting hung at "Waiting for root device" although for some reason every now and then on retry's it would load a bit further until I got the now dreaded "calibation failed" message. I have since gave up on leo4allv3 and started working with Kalyway amd-intel10.5.2 which was almost an effortless install on my old dell insprion5160 with a p4.

Kalyway- Here is the issue I get the same issue as with leo4all with the Calibation but not the root devise problem and if I type cpus=2 at the darwin prompt it will load for a while and then hang at ntfs disk??????. Hopefully someone can help point me in the right direction here. And Just before the hang this is the screen message "
CODE SIGNING: cs_invalid_page: p=102[lssave] clearing CS_VALID

And yes I have spent countless hours searching the forums and have found no solutions
Thanks.
