Hardware Setup
This chapter includes sections of setting up jumpers on the
motherboard, the system memory configuration, the cache
memory configuration, and attaching the connectors. Refer
back to this chapter when you need to upgrade or
reconfigure your system and remember to turn off the
power of the system as well as all peripheral devices before
performing any work on the system.
Symbols used in this chapter are described below:
For 2-pin jumper:
Ð Close the jumper by inserting the jumper
cap over the two pins of the jumper.
Ð Open the jumper by removing the
jumper cap.
For 3-pin jumper:
123
Ð Close pins 1 and 2 with an jumper cap.
123
Ð Close pins 2 and 3 with an jumper cap.

System Memory Configuration
This 82440FX motherboard supports 72-pin SIMMs of 4MB,
8MB, 16MB, or 32MB to form a memory size between 8MB
to 384MB. Each bank must have 2 pcs of DRAM modules
(w/i same size and type) installed. 82440FX chipsets
provide ÒTable-FreeÓ function. It means that users can
install DRAM with any configuration and in any bank, and
that is why the DRAM table is not needed.

Cooling FAN Settings
Note: Install a fan facing the heat sink, for better cooling effect,
Installation
1. Place CPU into your socket and put CPU cooler on top of
CPU as shown in the following drawing. Slide one side
hole of clip into the key way of the socket, then
