1-2 Chapter1
Sets You Free From the Y2K Threat
The potential threat of Year 2000 (Y2K) problems are making everyone very nervous. The
Y2K issue applies to almost any device, firmware, or software that operates on or with year
based dates. This problem is caused by a design flaw in the Real Time Clock (RTC) unit.
The RTC only changes the last two digits of the year code, but not the century information.
As a result, when it comes to 12:00 AM January 1, 2000 the RTC will switch from
December 31 11:59 PM 1999 to 12:00 AM January 1 1900.
Y2K compliance deals with the date change over from 31 December 1999 to 1 January 2000,
and with recording and reporting of all dates from the RTC including leap year dates. This
motherboard is free from the Y2K problem because its BIOS are Y2K compliant.
Please Note
If the operating system or application software cannot handle Year 2000 dates, you will
still be facing the Y2K threat because it is not a hardware problem that relates to the
motherboard itself. According to Award BIOS, it is BIOS source code released after 31
May 1995 complies with all known Y2K issues; however, it may still fail the 2000.exe
test. Award has modified its BIOS source code to accommodate the requirements of
2000.exe. Award BIOS source code issued later than 18 November 1996 passes the
NTSL 2000.exe test program.

Chapter 2. Installing the Motherboard
The BM6 motherboard not only provides all of the standard equipment for personal
computers, but also provides great flexibility for meeting future upgrade demands. This
chapter will introduce, step by step, all the standard equipment and will also present, as
completely as possible, future upgrade capabilities. This motherboard is able to support all
Intel Celeron™ PPGA processors now on the market. (For details, see specifications in
Chapter 1.)
This chapter is organized according to the following features:
2-1 Installing the Motherboard to the Chassis
2-2 Installation of the Celeron™ PPGA processor
2-3 Installing System Memory
2-4 Connectors, Headers and Switches
NNNN
Before you install or unplug any connectors or add-on cards, please remember to turn the
ATX power supply switch off (fully turn the +5V standby power off), or take the power cord
off. Otherwise, you may cause the motherboard components or add-on cards to malfunction
or be damaged.

User Friendly Instructions
Our objective is to enable the novice computer user to perform the installation by himself.
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:
l with studs
l or with spacers
Please refer to the figure 2-1 that shows the studs and spacers, they may have several types,
but all look like the figures below:
In principle, the best way to attach the
motherboard is with studs, and 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:
BM6
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, don’t worry, you can still attach the spacers
to the mounting holes. Just cut the bottom portion of spacers (the spacer may be a little
hard to cut off, so be careful of 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 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 Celeron™ PPGA processor
The Intel® Celeron™ PPGA package processor installation, is easy, like Pentium® processors
before. Because it uses the “Socket 370” ZIF (Zero Insertion Force) socket, it can easily let
you fix the processor on to its position firmly.
Figure 2-3 shows you what the 370 socket looks like, and how to open the lever. Its pin
count is more than socket 7. Therefore, the Pentium level processor cannot be inserted into
socket 370.
User’s Manual
When you raise the lever, you have loosened
the socket lock. Please raise the lever to the end,
and prepare to insert the processor. Next, you
need to align the processor pin 1 to socket pin 1.
If you put it in the wrong direction, you will not
be able to insert the processor easily, and
processor pins will not fully go into the socket.
If that is the case, please change the direction,
until it easily and fully inserts into the 370
socket. See Figure 2-4.
When you finish the above, then push the lever
down to its original position, and you should
feel the lever lock up the 370 socket. You have
then finished the processor installation.
2-4 Chapter2
2-3. Installing System Memory
This motherboard provides three 168-pin DIMM sites for memory expansion. The DIMM
sockets support 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64 (64MB), 16Mx64
(128MB), and 32Mx64 (256MB) or double sided DIMM modules. Minimum memory size
is 8MB and maximum memory size is 768MB SDRAM. There are three Memory module
sockets on the system board. (Total six banks)
In order to create a memory array, certain rules must be followed. The following set of rules
allows for optimum configurations.
l The memory array is 64 or 72 bits wide. (depending on with or without parity)
l Those modules can be populated in any order.
l Supports single and double density DIMMS.
Table 2-1. Valid Memory Configurations

8MB ~ 256MB
Generally, installing SDRAM modules to your motherboard is an easy thing to do. You can
refer to figure 2-5 to see what a 168-pin PC100 SDRAM module looks like.
Unlike installing SIMMs,
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 from your computer.
Step 2. Remove the computer’s chassis cover.
BM6
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 keyed to the socket. You can refer to figure 2-6 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 the both sides.

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 connectors, headers and switches here, and tell you how to connect
them. Please pay attention and read the whole section for necessary information before
attempting to finish all of the hardware installation inside the computer chassis.
Figure 2-7 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 on 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.

feature, then you can connect the specific
cable from the audio adapter to this header.
SB-LINK™ combines Intel's PC-PCI and
"Serialized IRQ" protocols. These
technologies can be found in Intel's TX, LX,
BX and newer core logic chipsets. This
technology provides the DMA and IRQ
signals present in ISA Bus today, but not
available on the PCI Bus. The SB-LINK
serves as a bridge between the motherboard and PCI sound card to deliver Sound card for
real-mode DOS games. Check to see if your card supports this.

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 (it’s a 3 1/2” drive used in
Japanese computer systems).
A floppy disk drive ribbon cable has 34
wires and two connectors to provide for 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.
Note
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.
User’s Manual
2-14 Chapter2
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.).
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”,
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
lThe 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. lA 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.
