CHAPTER 2 JUMPER SETTINGS
2.1 JUMPERS PRESENTATION
Pins 1 and 2 are shorted with a jumper cap.
1 2 3
Pins 2 and 3 are shorted with a jumper cap.
1 2 3
The jumper is shorted when the jumper cap is placed
over the two pins of the jumper.
The jumper is open when the jumper cap is removed
from jumper.
Jumpers Convention
Different color of jumper caps (mini-jumpers) are used on the board to represent
different usage of the jumpers:
Red: CPU Clock setting
Black: Other

CHAPTER 3 CONNECTOR
CONFIGURATION
Once the mainboard has been fastened into system case, the next step is to connect the internal
cables. The internal cables are wire leads with plastic female connectors that attach to the
connectors. The mainboard connectors have varying numbers of pins and are the points of
contact between the mainboard and other parts of the computer.
