Hi I just installed leopard iAtkos release 10.5.7 which i think is the newest. The installation went fine but when i restart it goes to that grey apple startup screen and does nothing both keybaord and mouse don't work at this point. I tried going to utilities and installing chameleon and the only difference is now theres this cartoon lizard loading screen where it gives me the option to choose which disk i want to boot then it goes to a somewhat different apple startup screen where it freezes again. I have a pentium 4 2.5ghz with 1gig of ram and my motherboard is an msi 845E max (or MS-6566E as it says in dxdiag). Can anyone please help me out I want this to work so badly.
