What is new in Arca OS kernel?
A: In short, the last kernel (core of the operating system) for OS/2 had some remaining issues which will be addressed in ArcaOS. Essentially, these issues involve running DOS windows, unloading modules which have been loaded into high memory, and some other areas affecting stability.
ArcaOS will include a new loader making it possible to run ArcaOS 5.0 on systems which might otherwise only see 512MB of memory instead of the full compliment of RAM installed. In addition, this new loader will allow the configuration of memory above 4GB as a RAM disk.
