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.

JC1: Speaker Connector
The speaker connector is a 4-pin connector for connecting
the system and the speaker. (See the following drawing for
jumper position.)
JC2: Reset Switch
The system board has a 2-pin connector for rebooting your
computer without having to turn off your power switch.
This prolongs the life of the systemÕs power supply.

JC5: SMI Switch
Toggle this jumper force the system to sleep and the system
wonÕt wake up until the hardware event is coming. (The
BIOS Power Management setting must be Enabled.)
JP15: Power On Switch
Connect the power switch to this connector (depend on your
ATX case).
HD1: IDE LED Activity Light
These connectors connect to the hard disk activity indicator
light on the case.
