Before you install the SQ578 mainboard into the system chassis you may find it convenient
to first configure the mainboard hardware. This section describes how to configure the
jumper settings, install memory modules, and how to attach the various system components.
Before using your computer you must review the following 7 steps:
1.
Jumper settings
2.
Installation of DRAM modules (SIMM or DIMM)
3.
Installation of the CPU
4.
Installation of expansion cards
5.
Installation of IDE, I/O, VGA cables(Option) connection., and Power Supply connection

be sure your System is Power Off.
3.1 Jumper Settings
You can configure the hardware options by setting jumpers on the mainboard. A jumper is a
set of two or more metal pins in a plastic base attached to the mainboard. A plastic “jumper
cap” with a metal (conductive) plate inside fits over two pins to create an electrical contact
or short between them. This contact establishes a hardware setting and is referred to as a
“closed” jumper setting.
Some jumper have two pins while others may have three or more. Jumpers are sometimes
combined into sets called jumper blocks where all the jumpers in the block must be set
together to establish a hardware setting. In this manual, the jumper settings will be
described graphically using a triangle (
s
) always marking pin 1. Those jumpers with two
pins will be shown as closed or open. A jumper is closed by placing the plastic jumper cap
over the two jumper pins and is opened by removing the jumper cap. Some jumpers are
oriented vertically and others horizontally with pin 1 marked as (

=P1).
