3.2.4 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 (page 51). 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.
