Those hardware settings are made through the use of jumper caps to connect jumper pins on the
main board.
The following examples show the conventions used in this chapter.
Insert a jumper pack on JP19
Row B-C to set CPU voltage
auto-detecting
Remove jumper pack from JP19
and insert mini on pin 1, 3, 4 on
Row A-B to set voltage on 3.3V
Insert mini jumpers on pin 1-2, 3-4
of JP1
Insert mini jumpers on pin 1-2, 7-8
and 9-10 of JP1
