You will normally leave the jumpers on the CPU card at their
default settings. If you need to use certain peripherals,
you will need to change some of those jumpers.

This also prevents using the external DAC as an audio interface,
and means you can't initialize the on-board QVGA display.

If you change this you'll want an updated boot loader putting
