This motherboard is designed for Intel’s new generation of Celeron™ processors. It supports
the Intel® Celeron™ processor, with the PPGA (Plastic Pin Grid Array package) 370-pin
design. Up to 256MB of memory, super I/O, and Green PC functions. The ZM6 has built-in
hardware monitoring functions (you can refer to Appendix C for detailed information), they
can monitor and protect your computer insuring a safe computing environment. It supports
both the PS/2 keyboard and PS/2 mouse wake up features (you can refer to page 3-33 Power
On Function for detailed information), letting you easily wake up your system by these
devices. The motherboard can provide high performance for workstations and meets the
requirements for desktop systems for multimedia in the future.
The PPGA processor is the next addition to the Intel® Celeron™ processor product line, it
implements a Dynamic Execution micro-architecture and executes MMX™ media
technology instructions for enhanced media and communication performance. The PPGA
processor also uses the same multi-transaction system bus used in the Pentium® II processor.
The processor also supports multiple low-power states such as AutoHALT, Stop-Grant, and
Deep Sleep to conserve power during idle times.
Figure 1-1. Intel® Celeron™PPGA package processor
The PPGA processor includes an integrated 128K second level cache with separated 16K
instruction and 16K data level one caches. The second level cache is capable of caching
4GB of system memory.

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 ZM6 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 Proceeding with the Installation 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.

2-2Chapter2
ZM6
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:
lwith studs
lor 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:

Installing the Motherboard 2-3
User’s Manual
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.
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.

2-4Chapter2
ZM6
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 256MB 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.
lThe memory array is 64 or 72 bits wide. (depending on with or without parity)
lThose modules can be populated in any order.
lSupports single and double density DIMMS.
Table 2-1. Valid Memory Configurations
Bank Memory Module Total Memory
Bank 0, 1
(DIMM1) 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 8MB ~ 256MB
Bank 2, 3
(DIMM2) 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 8MB ~ 256MB
Bank 2, 3
(DIMM3) 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 8MB ~ 256MB
Total System Memory 8MB ~ 256MB
Note: 1.When you install RAM modules, we strongly suggest that you install them in the
order of filling DIMM 1~ DIMM3. If you install RAM modules disregarded this
order, you may encounter some problems. One of problems might be that you can’t
boot up the system. Another possible problem is that the BIOS won’t be able to
detect the memory you installed.
Note 2. DIMM 3 control signals are shared with DIMM 2. Therefore, if you insert a double
sided RAM module into both DIMM 2 and DIMM 3 at the same time, two
situations will occur. One is when you use a PC-100 RAM (with an SPD chip on the
Ram module), you will not be able to boot up the system. The other situation is that
if you use a RAM module without SPD, you will only be able to get one RAM
module memory size used on your system. Therefore, we strongly suggest that you
do not insert a double sided RAM module in both DIMM 2 and DIMM 3. You
should only insert one doubled sided RAM module into DIMM2 or DIMM 3 at a
time, or you can install two single sided RAM modules into both DIMM 2 and
DIMM 3.

Installing the Motherboard 2-5
User’s Manual
Note 3. According this motherboard layout design, DIMM 2 and DIMM 3 share two banks.
Therefore, please don’t install RAM modules that will occupy two banks into both
DIMM 2 and DIMM 3 at the same time. There are two main types of RAM
modules on the market now, one is single sided and the other is double sided. The
single sided RAM module doesn’t mean it only occupies one bank, and double
sided RAM module also doesn’t mean it will occupy two banks. When you want to
install RAM modules into both DIMM 2 and DIMM 3 at the same time, please
make sure how many banks of RAM the modules will occupy. For this issue, you
can refer to the specifications of your RAM module from the manufacturer.
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.
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

2-6Chapter2
ZM6
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.
Figure 2-7. All Connectors and Headers for the ZM6
First, Let’s see the headers that ZM6 uses, and what their functions are.

2-8Chapter2
ZM6
(1) ATX1: ATX Power Input Connector
Caution
If the power supply connectors are not properly attached to the ATX1 power supply, the
power supply or add-on cards may be damaged.
Attach the connector from the power supply
to the ATX1 connector here. Remember you
have to push the connector from the ATX
power supply firmly to the end with the
ATX1 connector, insuring that you have a
good connection.
Note: Watch the pin position and the
orientation
(2A) and (2B) Headers: CPUFAN and FAN2 Headers
Attach the connector from the individual
CPU fan to the header named CPUFAN, and
attach the connector from the chassis fan to
FAN2 header.
You must attach the CPU fan to the
processor, or your processor will work
abnormally or may be damaged by
overheating. Also, if you want the computer
case’s internal temperature to be kept steady
and not too high, you had better connect the
chassis fan to reach this goal.
Note: Watch the pin position and the orientation

Installing the Motherboard 2-9
User’s Manual
(3) IR: IR Header (Infrared)
There is a specific orientation for pins 1
through 5, attach the connector from the IR
KIT or IR device to the IR header. This
motherboard supports standard IR transfer
rates.
Note: Watch the pin position and the
orientation
(4) SB-Link: SB-Link™ Header
If your PCI audio adapter supports this
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.
Note: Watch the pin position and the orientation
(5) WOR1: Wake On Ring Header
If you have an internal modem adapter that
supports this feature, then you can connect
the specific cable from the internal modem
adapter to this header. This feature lets you
wake up your computer via remote control
through the modem.
Note: Watch the pin position and the
orientation

2-10 Chapter2
ZM6
(6) WOL1: Wake on LAN Header
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, like
using the Intel® LDCM® utility or other
similar utilities.
Note: Watch the pin position and the orientation
(7A), (7B) and (7C): RT1, RT2 and RT3 Header
The Thermistors RT1 and RT3 are already
onboard, RT1 (or R317) is usedto detect the
system environment temperature, and RT3
is usedto detect the CPU temperature. The
RT2 is for you to connect an additional
thermistor to detect the temperature in the
location of your choice. You can buy the
thermistor at an electronics store, and ask for
a 10KΩthermistor which should be OK.
Please don’t use too long of a lead wire for
the thermistor.
(8) CCMOS1: CMOS Discharge Jumper
Jumper CCMOS1 discharge CMOS
memory. When you install the motherboard,
make sure this jumper is set for normal
operation (pin 1 and 2 shorted). See figure
