Caution
Do not alter any jumpers or switch settings other than those identified here,
unless told to by your supplier or an authorized maintainer. Otherwise, you
may damage the system processor, the motherboard, or both.
There are only a few jumpers on the motherboard that you may
need to alter. All others are set at the factory and should not be
changed.
In this section, “1-2” means the jumper should be fitted across pins 1
and 2, “2-3” means the jumper should be fitted across pins 2 and 3,
and so on. “Open” means that no jumper should be fitted; “Closed”
means that all jumpers should be fitted.
On the motherboard, pin 1 of each jumper block is indicated by a
small triangle marking.
