First it just froze while booting to MorphOS. I could see MorphOS logo but when it attempted to open Ambient screen it just froze. The same when booting from CD until I disconnected stuff from 2nd IDE port and I could boot MorphOS properly from CD again. But after couple of attempts it died completely and can not get OF prompt anymore.

With null modem cable I was able to see it is freezing when configuring legacy drives.
