Chapter 1. Introduction of SX7-533 Features
1-1. Features of SX7-533 Motherboard
This motherboard is designed for use with Intel’s latest generation of Pentium® 4 478 pins processors.
Based on the new SiS 645DX chipsets (SiS 645DX & SiS 961B), this motherboard supports 400 MHz /
533 MHz system bus (100 MHz / 133 MHz Quad Data Rate) and SiS MuTIOL
Technology connecting with SiS 961B MuTIOL
®
Media IO. The In tel® Pentium® 4 processors feature the
new NetBurst Micro-architecture, which enriches the user experience in Net surfing and Multimedia
activities.
The AGP interface can support an external AGP slot with AGP 1X/2X/4X capability and Fast Writes. A
high bandwidth and mature SiS MuTIOL
961B MuTIOL
®
Media I/O together. SiS MuTIOL® technology is developed into three layers. The
®
technology is incorporated to connect the SiS 645DX and SiS
Multi-threaded I/O Link Layer delivers 1.2 GB of bandwidth to connect embedded DMA Master devices
and external PCI masters to interface with the Multi-threaded I/O Link layer, the Multi-threaded I/O Link
Encoder/Decoder in the SiS 961B to transfer data with 533 MB/Sec of bandwidth to/from Multi-threaded
I/O Link layer to/from SiS 645DX, and the Multi-threaded I/O Link Encoder/Decoder in SiS 645DX to
transfer data with 533 MB/Sec to/from the memory sub-system to/from the Multi-threaded I/O Link
Encoder/Decoder in SiS 961B.
The SiS 645DX chipset used in this motherboard supports three DDR DIMMs for a maximum of up to 3
GB. The memory controller can support both DDR (up to DDR PC 2700, it running on 166 MHz and
triggered by rising and falling edge) and SDR. It can offer bandwidth up to 2.7 GB/Sec under DDR 333
and 1 GB/Sec under PC 133 in order to sustain the bandwidth demand from the host processor, as well as
the multi I/O masters and AGP masters. DDR SDRAM is the newest memory standard, and it provides
maximum translation bandwidth and also greatly improves data transaction delays. This feature improves
whole system performance and speed, especially in multimedia environment applications.
The SX7-533 has a built in Ultra DMA 133 function. This means that it provides speedier HDD
throughput boosting overall system performance. Ultra DMA 133 is the new standard for IDE devices. It
enhances existing Ultra DMA 33 technology by increasing both performance and data integrity. This new
high-speed interface almost doubles the Ultra DMA 66 burst data transfer rate to 133 Mbytes/sec. The
result is maximum disc performance using the current PCI local bus environment. Another benefit is you
can connect four IDE devices in your system through either Ultra DMA 66 or Ultra DMA 100 and Ultra
DMA 133. You will have more flexibility to expand your computer system.
SX7-533 includes newest ALC650 6-channel audio CODEC. The ABIT 6-channel kit called CA-20
(Optional), which includes extra 4-channel signal output jack, S/PDIF Out and two USB ports (USB 1.1).
This motherboard also supports six PCI slots and one AGP slot. In addition, this motherboard gives users
enormous flexibility through ABIT’s SoftMenu
™
III with plenty clock frequency selections. The user is
able to alter both the FSB speed and the multiplier to get the CPU processing speed of your choice. This
motherboard has built-in hardware monitoring functions that monitors and protects your computer,
ensuring a safe computing environment.

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
like 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.
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, don’t worry, you can still attach the spacers to the mounting holes. Just
cut the bottom portion of spacers (the spacer they may be a little hard to cut, so be careful with your
hands). 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, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact
any 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. Install Pentium® 4 Processor and Heatsink Supporting-Base
This motherboard provides a ZIF (Zero Insertion
Force) Socket 478 to install Intel
®
Pentium® 4
processor. The processor you bought should include a
heatsink and cooling fan kit along with. If that’s not
the case, buy one specially designed for Pentium
®
4
Socket 478. Please refer to figure 2-3 to install the
processor.
1. Locate the Socket 478. Fasten the heatsink
supporting-base onto the motherboard.
Attention
If you are using chassis specially designed for
Pentium® 4, please pay attention to the location of
metal studs or spacers if they are already installed
on the chassis. Be careful not let the metal studs
or spacers contact the printed circuit wire or parts
on the PCB.
2. Pull the processor socket lever sideways away
from the socket and then upwards to 90 degrees.
Insert the processor with the correct orientation.
Do not use extra force to insert processor; it only
fits in one orientation. Push down the socket lever
while holding down the processor.
3. Put the heatsink face down onto the processor until
it completely covers the processor.
4. Put the heatsink supporting-cover onto the
heatsink. Make sure all four locking clasps on each
side of the supporting cover reach in the locking
holes.
5. Push down the retaining clip on both sides of the
supporting cover to lock together with the
supporting base. Watch the direction you push
down on the clip.
6. The heatsink supporting cover and base should
now firmly lock together with the heatsink inside.
Attention
Do not forget to set the correct bus frequency and
multiple for your processor.

DIMM
Generally, installing DDR SDRAM modules to your
motherboard is an easy thing to do. You can refer to
Figure 2-4 to see what a 184-pin PC 1600, PC 2100
& PC 2700 DDR SDRAM module looks like.
Unlike installing SIMMs, DIMMs may be
“snapped” directly into the socket. Note: Certain
DDR 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 DDR DIMM socket.
The following procedure will show you how to
install a DDR DIMM module into a DDR DIMM
socket.
Step 1. Before you install the memory module,
Step 2. Remove the computer’s chassis cover.
Step 3. Before touching any electronic components,
64 MB ~ 1 GB
64 MB ~ 1 GB
64 MB ~ 1 GB
64 MB ~ 2 GB
64 MB ~ 3 GB
please place the computer power switch in
the off position and disconnect the AC
power cord from your computer.
make sure you first touch an unpainted,
grounded metal object to discharge any
static electricity stored on your clothing or
body.
SX7-533
Installing the Motherboard
Step 4. Locate your computer’s 184-pin memory expansion DDR DIMM socket.
Step 5. Insert the DDR DIMM module into the expansion socket as shown in the illustration. Note how
the module is keyed to the socket. You can refer to Figure 2-5 for the details. This insures the
DDR DIMM module will be plugged into the socket in one way only. Firmly press the DDR
DIMM module into DDR DIMM socket, making certain the module is completely seated in the
DDR DIMM socket.
Step 6. Once the DDR 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 DDR DIMM module fully into the DDR DIMM socket, the eject tab should be
locked into the DDR DIMM module very firmly and fit into its indention on the both sides.
It is difficult to differentiate between the PC 1600, PC 2100 and PC 2700 DDR SDRAM modules from
the exterior. The only way you can identify them is to look at the sticker on the DDR SDRAM module.
The sticker will tell you which kind of structure module the DDR SDRAM is.

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
hardware installation inside the computer chassis.
Figure 2-6 shows you all of the connectors and headers that we’ll discuss in the next section, and you can
use this diagram to visually locate each connector and header we describe.
All connectors, headers and switches mentioned here will depend on your system configuration. Some
features you may (or may not) have and need to be connected or configured depending on the peripheral.
If your system doesn't have such add-on cards or switches, you can safely ignore some special feature
connectors.
Note
Please do not change the small DIP switchs setting on SW1, as wrong settings may prevent your
computer from booting. Please go to the BIOS “SoftMenu III Setup” menu to setting CPUs
parameters.

Figure 2-6. All Connectors and Headers for the SX7-533
First, Let’s see the headers that SX7-533 uses, and what their functions are. We will show you all the
connectors and headers.
(1). ATXPWR1 and ATX12V1: ATX Power Input Connectors
The Pentium® 4 requires a power supplier different
from the regular one. It’s a newly designed
ATX12V1 power with 300W, 20A +5VDC capacity
at least for heavily loaded system, and 720mA
+5VSB at least for supporting Wake-On-LAN
(WOL) or Wake-On-Ring (WOR) features.
Attach the connector from the power supply to the
ATXPWR1 and ATX12V1 connectors here.
Remember you have to push the connector from the
ATX power supply firmly to the end with the
ATXPWR1 and ATX12V1 connectors, insuring that
you have a good connection.
Note: Watch the pin position and the orientation.
SX7-533
Installing the Motherboard
Caution
If the power supply connectors are not properly attached to the ATX power supply, the power supply
or add-on cards may be damaged.
One end of AC power core connects to ATX power supply, and the other end (AC plug) will plug into
the wall outlet. Be aware that when facing the wall outlet, the round hole is in the middle. The right
side slot is called ground wire slot. It has a longer slot length than the left side slot. The left side slot is
called the live wire slot. You can use an electroscope to detect its polarity or you can use a voltage
meter to measure the voltage of both slot sides. If you insert an electroscope into the live wire slot, the
electroscope will light up. Using a voltage meter, you will find that the live wire slot will register a
higher voltage.
If you reverse the polarity of AC plug, it may affect the life of computer equipment, or cause an
electric shock when you touch the computer chassis. We suggest that you plug the computer AC plug
to a three-hole wall outlet for better safety and to avoid electric shock.
2-7
(2). CPUFAN1, CHAFAN1 and PWRFAN1 headers
Attach the connector from the CPU fan to the header
named CPUFAN1 and connector from the chassis
fan to the header CHAFAN1. Attach the connector
from the power fan to PWRFAN1 header.
You must attach the CPU fan to the processor, or
your processor will work abnormally or may be
damaged by overheating. To prevent the computer
chassis internal temperature from getting too high,
also connect the chassis fan.
Note: Watch the pin position and the orientation

1.2M, 5.25”, 720K, 3.5’’, 1.44M, 3.5” or 2.88M,
3.5” floppy disk drive.
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.

(10). IDE1and IDE2 Connectors
This motherboard provides two IDE ports (IDE1 &
IDE2) to connect up to four IDE devices in Ultra
DMA 133 mode by Ultra DMA 66 ribbon cables.
Each cable has 40-pin 80-conductor and three
connectors, providing two hard drive connections
with the motherboard. Connect the single end (blue
connector) at the longer length of ribbon cable to the
IDE port on motherboard, and the other two ends
(gray and black connector) at the shorter length of
the ribbon cable to the connectors on hard drives.
If you want to connect two hard drives together
through one IDE channel, you must configure the
second drive to Slave mode after the first Master
drive. Please refer to the HDD documentation for jumper
settings. The first drive connected to IDE1 is usually
referred to as “Primary Master”, and the second drive as
“Primary Slave”. The first drive connected to IDE2 is
referred to as “Secondary Master” and the second drive
as “Secondary Slave”.
Keep away from connecting one legacy slow speed
device, like CD-ROM, together with another hard disk
drive on the same IDE channel; this will decrease your
integral system performance.

Ribbon Cable Outline
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.
! To connect Ultra DMA 133 and Ultra DMA 100 devices on IDE1and IDE2, an Ultra DMA 66
cable is required.
! A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to
the IDE connector pin 1 before inserting the wire connector into the IDE connector.

Introducing the BIOS
3-1
Chapter 3. Introducing the BIOS
The BIOS is a program located on a Flash Memory chip on the motherboard. This program will not be
lost when you turn the computer off. This program is also referred to as the boot program. It is the only
channel the hardware circuit has to communicate with the operating system. Its main function is to
manage the setup of the motherboard and interface card parameters, including simple parameters such as
time, date, hard disk drive, as well as more complex parameters such as hardware synchronization, device
operating mode, SOFT MENU
normally, or will operate at its best, only if all of these parameters are correctly configured through the
BIOS.
Don’t change the parameters inside the BIOS unless you fully understand the meanings
(
and consequences
The parameters inside the BIOS are used to setup the hardware synchronization or the
device-operating mode. If the parameters are not correct, they will produce errors, the computer will
crash, and sometimes you will even not be able to boot the computer after it has crashed. We
recommend that you do not change the parameters inside the BIOS unless you are very familiar with
them. If you are not able to boot your computer anymore, please refer to the section “CCMOS1
Discharge Jumpr” in Chapter 2 to see how to discharge the CMOS date.
When you start the computer, the BIOS program controls it. The BIOS first operates an auto-diagnostic
test called POST (Power On Self Test) for all of the necessary hardware. It then configures the parameters
of the hardware synchronization, and detects all of the hardware. Only when these tasks are completed
does it give up control of the computer to the program to the next level, which is the operating system
(OS). Since the BIOS is the only channel for hardware and software to communicate, it is the key factor
for system stability, and in insuring that your system performs at its best. After the BIOS has achieved the
auto-diagnostic and auto-detection operations, it will display the following message:
The message will be displayed for three to five seconds, if you press the Del key, you will access the
BIOS Setup menu. At that moment, the BIOS will display the following message:
™
III features and setup of processor speed. The computer will operate
