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

2.7 MEMORY CONFIGUARTION
When 100MHz Front Size Bus Processor is used. SDRAM DIMMs with PC/100
specification and Serial Presence Defect (SPD) data structure are required. The
mainboard lets user upgrade system memory via DIMM sockets on the mainboard.
On board memory is located in eight banks: Row 0 - 7. Four DIMM sockets are
provided for 3.3V Synchronous DRAM. Table 5 provides the typical memory
configurations supported by the mainboard.

The maximum memory size is up to 1GB. The size of each DIMM can be 8MB,
16MB, 32MB, 64MB, 128MB or 256MB.

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.

3.2 JP10 - IrDA CONNECTOR
JP10 is an IrDA connector that uses UART2 as interface of IrDA Infrared and HP
SIR.
