CRM is used to refer to the graphics hardware of the O2 an O2+ systems. One distinct feature of the O2/O2+ is the Unified Memory Architecture (UMA). Because of this the graphics hardware is highly integrated with the host system. Also, unlike other systems the O2/O2+ has an integrated mainboard which includes CPU, memory, graphics and of course I/O. The only option relating to the O2/O2+ graphics hardware is the Dual Display Option which includes an add-in board and splits the output of the O2/O2+ across two screens.
