Num lock, caps lock and scroll lock

The three leds on the right side of the case are connected to GPIO pins. Setting the pin to output and writing a 0 to it will enable the led; setting it to input or writing a 1 will switch it off.

The caps lock led is on pin 27 of port 0; num lock is on pin 22 of port 2 and scroll lock (named "network" in the Linux source) is on pin 9 of port 0.
