User Friendly Instructions

Our objective is to enable the novice computer user to perform the installation by him or herself. We have attempted to write this document in a very clear, concise and descriptive manner to help overcome any obstacles you may face during installation. Please read our instructions carefully and follow them step-by-step.

User’s Manual

2-2	Chapter2

2-1. Installing the Motherboard to the Chassis

Most computer chassis will have a base on which there will be many mounting holes that allows the motherboard to be securely attached and at the same time, prevents short circuits. There are two ways to attach the motherboard to the base of chassis:

!with studs

!or with spacers

Please refer to figure 2-1, which shows the studs and spacers. There may be several types, but all look similar to the figures below:

In principle, the best way to attach the motherboard is with studs. Only if you are unable to do this should you attach the board with spacers. Take a careful look at the motherboard and you will see many mounting holes on it. Line these holes up with the mounting holes on the base. If the holes line up and there are screw holes

this means you can attach the motherboard with studs. If the holes line up and there are only slots, this means you can only attach the motherboard with spacers. Take the tip of the spacers and insert them into the slots. After doing this to all the slots, you can slide the motherboard into position aligned with the slots. After the motherboard has been positioned, check to make sure everything is OK before putting the casing back on.

Figure 2-2 shows you the way to affix the motherboard using studs or spacers:

SL6

Installing the Motherboard	2-3

Note

If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are no slots to attach the spacers, do not despair, you can still attach the spacers to the mounting holes. Just cut the bottom portion of the spacers (the spacers may be a little hard to cut , so mind your fingers). In this way, you can still attach the motherboard to the base without worrying about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard PCB surface as the circuit wire may be too near the hole. Be careful. Do not let the screw contact the printed circuit wire or parts on the PCB that are near the fixing hole. Otherwise it may damage the board or cause board malfunctioning.

2-2. Installation of the Pentium III CPU

The installation method for the CPU is printed on the package of the retention mechanism that comes with the motherboard. You can refer to it while you install the CPU.

Note:

!Installing a heat sink and cooling fan is necessary for proper heat dissipation from your CPU. Failing to install these items may result in overheating and damage of your CPU.

!Please refer to your boxed processor installation or other documentation attached with your CPU for detailed installing instructions.

User’s Manual

2-4	Chapter2

2-3. Installing System Memory

This motherboard provides three 168-pin DIMM sites for memory expansion. The DIMM sockets support 8Mx64 (64MB), 16Mx64 (128MB), 32Mx64 and (256MB) DIMM modules. Minimum memory size is 64MB and maximum memory size is 512MB SDRAM. In order to create a memory array, certain rules must be followed. The following set of rules allows for optimum configurations.

!The memory array is 64 or 72 bits wide. (depending on with or without parity)

!Those modules can be populated in any order.

!Supports single and double density DIMMS.

Table 2-1. Valid Memory Configurations

Bank		Memory Module	Total Memory
Bank 0, 1		8MB, 16MB, 32MB,	8MB ~ 512MB
(DIMM1)		64MB, 128MB
Bank 2, 3		8MB, 16MB, 32MB,	8MB ~ 512MB
(DIMM2)		64MB, 128MB
Bank 4, 5		8MB, 16MB, 32MB,	8MB ~ 512MB
(DIMM3)		64MB, 128MB
	Total System Memory		8MB ~ 512MB

Generally, installing SDRAM modules to your motherboard is an easy thing to do. You can refer to figure 2-3 to see what a 168-pin PC100 & PC133 SDRAM module looks like.

Figure 2-3 PC100/PC133/VCM Module and

Component Mark

DIMMs may be "snapped" directly into the socket. Note: Certain DIMM sockets have minor physical differences. If your module doesn't seem to fit, please do not force it into the socket as you may damaged your memory module or DIMM socket.

The following procedure will show you how to install a DIMM module into a DIMM socket.

Step 1. Before you install the memory module, please place the computer power switch in the off position and disconnect the AC power cord.

Step 2. Remove the computer’s chassis cover.

SL6

	Installing the Motherboard		2-5
		Step 3.	Before touching any electronic
		components, make sure you first touch
		an unpainted, grounded metal object to
		discharge any static electricity stored on
		your clothing or body.
		Step 4.	Locate your computer’s 168-pin
		memory expansion DIMM socket.
		Step 5.	Insert the DIMM module into
		the expansion socket as shown in the
		illustration. Note how the module is
	Figure 2-4. Memory module installation
		keyed to the socket. You can refer to

figure 2-4 for the details. This insures the DIMM module will be plugged into the socket in one way only. Firmly press the DIMM module into the DIMM socket, making certain the module is completely seated in the DIMM socket.

Step 6. Once the DIMM module has been installed, the installation is complete and the computer’s cover can be replaced. Or you can continue to install other devices and add-on cards that are mentioned in the following section.

Note

When you install a DIMM module fully into the DIMM socket, the eject tab should be locked into the DIMM module very firmly and fit into its indention on both sides.

It is difficult to differentiate between the PC100, PC133 SDRAM and VCM DRAM modules from the exterior. The only way to identify them is through the sticker on the RAM module.

2-4. Connectors, Headers and Switches

Inside the case of any computer several cables and plugs have to be connected. These cables and plugs are usually connected one-by-one to connectors located on the motherboard. You need to carefully pay attention to any connection orientation the cables may have and, if any, notice the position of the first pin of the connector. In the explanations that follow, we will describe the significance of the first pin.

We will show you all of the connectors, headers and switches here, and tell you how to connect them. Please pay attention and read the entire section for necessary information before attempting to finish all of the hardware installation inside the computer chassis.

Figure 2-5 shows you all of the connectors and headers that we’ll discuss in the next section, you can use this diagram to visually locate each connector and header we describe.

All connectors, headers and switches mentioned here will depend upon your system configuration. Some features you may (or may not) have and need to connect or configure depending on the peripheral. If your system doesn't have such add-on cards or switches you can ignore some special feature connectors.

Figure 2-5. All Connectors and Headers for the SL6

SL6

Installing the Motherboard	2-7

First, Let’s look at the headers that the SL6 uses, and what their functions are.

(1) ATXPWR1: ATX Power Input Connector

Caution

If the power supply connectors are not properly attached to the ATXPR1 power supply, the power supply or add-on cards may be damaged.

Attach the connector from the power supply to the ATXPR1 connector here. Remember

ATXPR1 you have to push the connector from the ATX power supply firmly into the ATXPR1

connector, ensuring that you have a good connection.

Note: Watch the pin position and the orientation

(2A)/(2B)/(2C): FAN1, FAN2 & FAN3 header

	Attach the connector from the individual
	CPU fan to the header named FAN1. The
	connector from the chassis fan should be
FAN2	attached to the header FAN3 and the
	connector from the power fan to FAN2.
FAN1	You must attach the CPU fan to the
	processor or your processor will work
	abnormally or may be damaged by
	overheating.	To keep the computer’s

internal temperature steady and not too high, connecting the chassis fan is imperative.

Note: Watch the pin position and the orientation

(3) IR1: IR Header (Infrared)

IR1

There is a specific orientation for pins 1 through 5, attach the connector from the IR KIT or IR device to the IR1 header (left row only). This motherboard supports standard IR transfer rates.

Note: Watch the pin position and the orientation

(4)WOL1: Wake on LAN Header

WOL1

If you have a network adapter that supports this feature, then you can connect the specific cable from the network adapter to this header. This feature lets you wake up your computer via remote control through a local area network. You may need a specific utility to control the wake up event, such as the PCnet Magic Packet utility or other similar utilities.

Note: Watch the pin position and the orientation

SL6

Installing the Motherboard	2-9
(5) SMB1: System Management Bus Connector

This connector is reserved for system management bus (SM bus). The SM bus is a specific implementation of an I2C bus. I2C is a multi-master bus, which means that multiple chips can be connected to the same bus and each one can act as a master by

SMB1 initiating a data transfer. If more than one master simultaneously tries to control the

bus, an arbitration procedure decides which

master gets priority.

Note: Watch the pin position and the orientation

(6) RT2 Thermister:
		The RT2 is a thermistor used to detect the
		system environmental temperature. It may
		also be called a system temperature detector.
		You can attach one end of the two-threaded
	RT2
		thermal cable that comes with the
		motherboard to the RT2 header, then tape
		the other end of the thermal cable on the
		CPU’s heat sink. Generally speaking, the
		location you tape the thermistor should be as

near the CPU chipset as possible and avoid having it near the CPU fan.

(7) CDIN1: Internal CD-ROM Drive Audio Cable Header

This header is for the internal CD-ROM CD1 drive audio cable connection. Please check your audio cable attached with the CDROM drive to see which type of connector

you have and then plug it into this header.

Let’s now see the I/O connectors that the SL6 uses, and what their functions are.

(11) FDC1 Connector

This 34-pin connector is called the “floppy disk drive connector”. You can connect a 360K, 5.25”, 1.2M, 5.25”, 720K, 3.5’’, 1.44M, 3.5” or 2.88M, 3.5” floppy disk drive. You can even connect a 3 Mode floppy disk drive (a 3 1/2” drive used in Japanese computer systems).

A floppy disk drive ribbon cable has 34 wires and two connectors to provide the connection of two floppy disk drives. After

connecting the single end to the FDC1, connect the two connectors on the other end to the floppy disk drives. In general, people only install one floppy disk drive on their computer system. The end attached to the longer length of ribbon should be attached to the motherboard connector.

User’s Manual

2-14	Chapter2

Note

A red mark on a wire typically designates the location of pin 1. You need to align pin 1 of the wire to pin 1 of the FDC1 connector and then insert.

(12) IDE1 and IDE2 Connectors

An IDE hard disk drive ribbon cable has 40 wires and two connectors to provide a connection for two IDE hard disk drives. After connecting the single end to the IDE1 (or IDE2), connect the two connectors on the other end to the IDE hard disk drives (or CD-ROM drive, LS-120, etc.). Again the connector attached to the longer ribbon length should be attached to the mobo.

Before you install a hard disk, there are

some things you need to be aware of:

♦“Primary” refers to the first connector on the motherboard; that is, the IDE1 connector on the motherboard.

♦“Secondary” refers to the second connector on the motherboard; that is, the IDE2 connector on the motherboard.

♦Two hard disks can be connected to each connector:

The first HDD is referred to as the “Master” and the second HDD is referred to as the “Slave”.

♦For performance issues, we strongly suggest you don’t install a CD-ROM drive on the same IDE channel as a hard disk. Otherwise, the system performance on this channel may drop. (how much depends on your CD-ROM drive performance)

Note

!The Master or Slave status of the hard disk drive is set on the hard disk itself. Please refer to the hard disk drive user’s manual.

!A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to the FDC1 connector pin 1, then insert the wire connector into the FDC1 connector.

SL6

Installing the Motherboard	2-15

The SL6 supports the Ultra ATA/66 (Also known as Ultra DMA/66) specification. It enhances existing Ultra ATA/33 technology by increasing both performance and data integrity. This new high-speed interface doubles the Ultra ATA/33 burst data transfer rate to 66.6 Mbytes/sec. The result is maximum disc performance using the current PCI local bus environment. Figure 2-8 shows you the different between the Ultra ATA/33 and Ultra ATA/66 Conductor Cable.

Figure 2-8. The difference between Ultra ATA/33 and Ultra ATA/66 Conductor Cables

Figure 2-9 shows you a photo of an Ultra ATA/66 Conductor Cable. An Ultra ATA/66capable cable is a 40-pin, 80-conductor cable with a black connector on one end, a blue connector on the other end and a gray connector in the middle. In addition, line 34 on the cable should be notched or cut (this may be difficult to see).

Ultra ATA/66 is backwards compatible with all Ultra ATA/33 systems, but it will be limited in its transfer mode to the Ultra ATA/33 (Ultra DMA Mode 2 - 33 Mbytes/sec) or PIO Mode 4 (16.6 Mbytes/sec). Ultra ATA/66 hard drives are 100 percent backward compatible with both Ultra ATA/33 and DMA and with existing ATA (IDE) hard drives, CD-ROM drives, and host systems.

The Ultra ATA/66 protocol and commands are designed to be compatible with existing ATA (IDE) devices and systems. Although a new 40-pin, 80-conductor cable is required for Ultra ATA/66, the chip set pin connector remains the same at 40. Hard drives that support Ultra ATA/66 also support Ultra ATA/33 and legacy ATA (IDE) specifications.

Figure 2-9. Photo of an Ultra

ATA/66 Conductor Cable

There are four requirements for attaining Ultra ATA/66:

*The drive must support Ultra ATA/66.

*The motherboard and system BIOS (or an add-in controller) must support Ultra ATA/66.

User’s Manual

2-16	Chapter2

*The operating system must support Direct Memory Access (DMA); Microsoft Windows 98 and Windows 95B (OSR2) support DMA.

*The cable must be an 80-pin conductor. The length should not exceed 18 inches. If all of the above requirements are met, you can enjoy the Ultra ATA/66 features of your computer system.

How to install the Ultra ATA/66 Cable Assembly:

Figure 2-10. How to connect an ATA/66 Cable to the Motherboard

&The BLUE connector MUST be plugged into the motherboard or your system will not work.

&Each connector on the Ultra ATA/66 cable assembly has a small polarization tab centrally located on the body of the plastic. This fits into the matching slot on the mating plugs on the motherboard and the drives, thus assuring positive mating (pin #1 to pin #1)

&The red line on the cable should be aligned with pin #1. On the drives this will result in the red line facing the power connector. Attach the BLUE connector to the appropriate 40 pin IDE plug on the motherboard.

&Attach the BLACK connector to the mating plug on the master hard drive. Attach the GREY connector to the mating plug on the slave drive (secondary hard drive, CD ROM, or tape drive). Please refer figure 2-10.
