MMULib: You need to build a MMUConfig for your memory configuration. In MMULib/Install should be an ARexx scipt named "BuildMMUConfig" that can do this automatically for you
Please read the MMU.guide in MMULIb/Docs - the section in that guide you need is called "Installation/Bonus feature for experts/For systems with non-autoconfiguring memory". I found it a very good and understandable read and since then I never looked back for the "2632" command.
