When using any of the downloaders, the Handy Board must first be put
into its bootstrap download mode. This is done by first turning the
board off, and then turning it on while holding down the STOP
button (the button closer to the pair of LEDs to the right of the
buttons). When the board is first turned on, these two LEDs should
light for about 
of a second and then both should turn
off. The STOP button must be held down continuously during this
sequence. When the board is powered on and both of these LEDs are
off, it is ready for bootstrap download.
