hello,today i installed Snow leopard with Iatkos but when i first booted OSX i saw the apple logo and the loading things below it,then the screen goes black as if there was no video input.

so please help me im a newbie and i never did this before.

thanks in advance and sorry for my english(isnt my main language)

First thing to check (if possible) is another methods of video output. I mean the VGA, DVI and HDMI ports.

If it's not possible, then try messing with Chameleon's Graphics Enabler parameter. (to disable it type "GraphicsEnabler"="No" in boot)
