Static Electricity Precaution

Static electricity can easily damage your SQ574 mainboard. Observing a few basic

precautions can help you safeguard against damage that could result in expensive repairs.

Follow the simple measures below to protect your equipment from static electricity damage:

Keep the mainboard and other system components in their anti-static packaging until you are

ready to install them.

Touch a grounded surface before you remove any system component from its protective anti-

static packaging. Unpacking and installation should be done on a grounded, anti-static mat.

The operator should be wearing an anti-static wristband, grounded at the same points as the

anti-static mat.

After removing the mainboard from its original packing, only place it on a grounded, anti-

static surface component side up. Immediately inspect the board for damage. Due to shifting

during shipping, it is suggested that the installer press down on all of the socket IC‘s to

ensure they are properly seated. Do this only with the board placed on a firm flat surface.

During configuration and installation, touch a grounded surface frequently to discharge any

static electrical charge that may have built up in your body. The best precaution is to wear a

grounded wrist strap. When handling the mainboard or an adapter card avoid touching its

components. Handle the mainboard and adapter cards either by the edges or by the adapter

card’s case mounting bracket.

3Installation Preview

Before you install the SQ574 mainboard into the system chassis you may find it convenient

to first configure the mainboard hardware. This section describes how to install memory

modules, and how to attach the various system components. Before using your computer you

must review the following 6 steps:

1. Installation of DRAM modules (SIMM or DIMM)

2. Installation of the CPU

3. Installation of expansion cards

4. Installation of IDE, I/O cables connection., and Power Supply connection

5. Installation of the Power Core to the System.

6. Setup of the system BIOS software

WARNING: When handling the system upgrade or plug in additional Add-On Card, please

be sure your System is Power Off.

3.1 Installation of DRAM modules (SIMM or DIMM)

3.1.1 SIMM (Single Inline Memory Module)

You can configure the system memory size in a variety of ways by using different

combinations of the four 72-pin DRAM SIMM. The memory must be 70ns (nanoseconds) or

faster using either Fast Page Mode or Extended Data Output (EDO) types. The memory

table below shows the different memory size combinations available. Please pay attention to

the following restrictions :

1) You must use one pair of sockets at a time in sequence ( i.e. SIMM1 and SIMM2, or all

four sockets at once).

2) Each pair of modules must be the same size and speed and may be single sided or

double-side. Module sizes: Single-side SIMMs: 4MB, 8MB, 16MB; Double-side

SIMMs: 8MB, 32MB, 64MB

3.1.3 Installation Procedure for SIMM

Insert SIMM into the

SIMM sockets at a 45

degree angle.

1) PIN1 of the SIMM must match with the PIN1 of the SIMM socket.

2) The module will only insert into the socket one way. An orientation cut-out will

prevent you from inserting it the wrong way.

3) Insert the SIMM into the SIMM socket at a 45 degree angle. If pin 1 of the SIMM does

not line up with pin 1 of the socket, the SIMM will not insert into the socket. After

inserting the SIMM module completely into the socket, push the SIMM module into a

vertical position.
