Linux pewnie przy 4MB tez bedzie mial klopoty.
Ciekawe rowniez co w tym PC (procz 8MB ramu) bylo?
 AHA2940W czy IDE , tridend czy paradise64 ?
No i oczywiscie kazdy chyba wie,ze dolozenie pamieci 8->16 ma ogromne
znaczenie, a 20->200 raczej niewielkie (przynajmniej na potrzeby xkobo)

Porownywales dwa systemy na dwoch roznych architekturach.
Jak skomentujesz cos takiego ;-) ????
