I want this OS to me but

Hello, I saw this OS a long time ago, but I had never used this before. I tryied to use the Beos PE but I have some problems with sound and video and mouse. And I read about this Haiku, where I can find the ISO to download. I have search in main web site but I didn’t find nothing there.
Could some one Help me?
