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, printer, display, speakers, microphone, LAN etc. If the board is mounted in a normal ATX

compliant case these connectors are located on the back side of the case. In the following sections we

will discuss each connector, going from left to right (looking onto the rear side of a desktop case) or from

top to bottom (tower case).

3.2.1 PS/2 keyboard and mouse

PS/2 mice and keyboards are connected via standard mini-DIN connectors. If you want to use the

keyboard or mouse to wake up the board from standby or suspend mode you have to activate this

functionality by adjusting the KBPWR jumper settings (see p. 47). With this jumper you can switch from

normal power supply (VCC) to standby power supply (SVCC) for keyboard/mouse. Some relevant

settings will have to be adjusted in BIOS setup.
