The MicroCross ADD2 DVI Card is designed to work on Intel Motherboards that have PCI-Express* slots and support SDVO (Serial Digital Video Output) technology. It will not work on motherboards or systems that support earlier DVO-based ADD (AGP Digital Display) cards. The ADD2 card features the SiI1364 SDVO-to-DVI (Digital Visual Interface) transmitter. The ADD2-N card (non lane-reversed) is designed to work with Intel** ATX systems and ADD2-R (lane reversed) card is designed to work with Intel BTX systems. They can be easily distinguished from their color code: ADD2-N is color coded (see Figure 1) and ADD2-R is color coded (see Figure 2). Both cards have been designed to meet the DVI 1.0 standard.
