I removed 4 GB from my ACER PC and Icaros Desktop (running native) seems to run much more stable than before, now that I have only 4 GB of RAM.. Icaros Desktop doesn't freeze anymore.. and a Filesystem Error that appeared before.. "AROS tried to access Block outside it's Partition" dissapeared and Icaros Desktop boots without Errors! I am talking of ABI V0!
It would be fine if sombody else could test that.. and probably the Bug could be fixed.. so that AROS doesn't freeze anymore if more than 4 GB are installed in the Computer!
