CHAPTER 2 JUMPER SETTINGS
2.1 JUMPERS PRESENTATION
Pins 1 and 2 are shorted with a jumper cap.

Pins 2 and 3 are shorted with a jumper cap.
1 2 3
The jumper is closed (on) when the jumper cap is placed
over the two pins of the jumper.
The jumper is open (off) when the jumper cap is removed
from jumper.
2.2 JUMPER CONVENTION
Different colour of jumper caps (mini-jumpers) are used on the board to represent
different usage of the jumpers:
Red : CPU Clock setting
Black: Other

Installation Guide
1. Mount the two RM Attach Mounts onto the motherboard from bottom side. These mounts
will be used to attach the RM Assembly.
2. Put the RM Assembly on the Slot 1 and use the four screws to fix RM Assembly to the RM
Attach Mount.
3. Install the Heatsink Support Base onto the motherboard, insert the two plastic nail to the hole
in the Heatsink Support Base as following diagram:

2.8 MEMORY CONFIGURATION
The Mainboard lets user upgrade system memory via SIMM sockets on the mainboard.
On-board memory is located in three banks: Bank 0, Bank 1, Bank 2 and Bank 3.
Two SIMM sockets are provided in each bank. User can install either 4M, 8M, 16M,
32M or 64M SIMM in each bank. Maximum memory size of system can be 512MB.
Note: The type of SIMM1/SIMM2 must be same.
The type of SIMM3/SIMM4 must be same.
The type of SIMM5/SIMM6 must be same.
The type of SIMM7/SIMM8 must be same.

Chapter 2

Install memory in any or all of the banks in any combination as following:
Bank 0 (SIMM7, 8) 4M, 8M, 16M, 32M or 64M
Bank 1 (SIMM5, 6) 4M, 8M, 16M, 32M or 64M
Bank 2 (SIMM3, 4) 4M, 8M, 16M, 32M or 64M
Bank 3 (SIMM1, 2) 4M, 8M, 16M, 32M or 64M
