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

2.5 MEMORY CONFIGUARTION
The mainboard lets user upgrade system memory via DIMM sockets on the
mainboard. On board memory is located in eight banks: Bank 0 - 7. Four DIMM
sockets are provided for EDO DRAM or Synchronous DRAM. Table 4 provide the
typical memory configurations supported by the mainboard.

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.
