No, for reasonable definitions of "properly". But the performance of a 32-bit CPU will suffer from the extension mechanisms needed to handle memory space bigger than 2^32, so if you are buying a new machine and plan to have over 4GB of RAM, a 64-bit CPU and OS would be preferable. -- Tapani Tarvainen -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
