I think so, becauce I have problem with MorphOS on my machine. I had been writen about this situation few months ago. On my A1200 MorphOS often freezes. Sometimes after few minutes, sometimes after 1-2 hours.

Here is a link where I wrote about this:

Somebody adviced me than to try to do somethink with my mobo. My brother (electronic engineer) tried to soldered some resistors. But it didn't help too.

So I think maybe my motherboard version is not proper.

So why I asked people what version of mobo they are using...
