3.2 Back Panel Connectors
The board complies with the ATX form factor and thus honours the "I/O Connector Area" as defined in the
ATX specification. A range of standard connectors are available: You can connect PS/2 keyboard and
mouse, displays, speakers, microphone, LAN, USB etc. If the board is mounted in a normal ATX compliant
case, these connectors are located on the back side of the case.
3.2.1 DVI Connectors
The CB1056 has one DVI-I connector and one DVI-D connector combined in one component (Foxconn
QH11121-DADF-4F). With an appropriate adapter, you can connect a CRT display to the DVI-I connector.
Digital DVI or HDMI displays can be attached to both connectors. The CPU's graphics system supports up
to two independent displays.
