Despite combining the heritage of Mandrakesoft and Connectiva, Mandriva is usually considered a second-tier Linux distribution. Nevertheless, the latest version, Mandriva Linux 2006, is well packaged and includes support for both 32-bit and 64-bit systems. The software comes on seven CDs, or one DVD (you actually get two DVDs -- one for 32-bit and one for 64-bit systems). Alternatively, you can download it from <a href="http://www.mandriva.com/">Mandriva's Web site</a>.
