Chapter 1. Introduction of WB6 Features
1-1.Features of This Motherboard
This motherboard is designed for a new generation CPUs. It supports the Intel SLOT1
structure (PentiumII/III and Celeronprocessors), up to 512 of memory, super I/O, and
Green PC functions. The motherboard provides high performance for server systems and
meets the requirements for desktop system for multimedia in the future.
The WB6 has a built in 2D & 3D graphics engines, and the integrated 24-bit 230MHz
RAMDAC can provide up to 1600*1200 resolution in 8-bit color at an 85Hz refresh rate.
The WB6 has 4MB SDRAM built in for graphic memory.
The WB6 uses the new generation Intel®810E chipset for more efficiency and high
integration of thesystem. TheWB6 will support Ultra ATA/66 IDEdevices. Ultra ATA/66 is
the new standard for IDE devices. 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. You can connect either Ultra
ATA/33 IDE devices or Ultra ATA/66 IDE devices to the IDE connectors on this
motherboard. The motherboard has built-in hardware monitoring functions, that can monitor
and protect your computer insuring a safe computing environment. The motherboard can
provide high performance for workstations and meets the requirements for desktop systems
for multimedia in the future.
What are the features of the Intel®810E chipset? It's structure is shown in Figure 1-4. It is a
combination of three chips: the FW82810E, FW82801AA and FW82802AB. The
FW82810E is called the GMCH chip, Graphics and Memory Controller Hub. The GMCH
functions and capabilities include:
!Support for a single Intel®Pentium II/III and Celeron™processor configuration
!64-bit GTL+ based system bus interface at 66MHz/100MHz/133MHz
!32-bit host address support
!64-bit system memory interface with optimized support for SDRAM at 100MHz
!Integrated 2D & 3D graphics engines
!Integrated H/W motion compensation engine
The FW82801AA is also called the ICH chipset, the, I/O Controller Hub. The ICH is a
highly integrated multifunctional component supporting the following functions and
capabilities:
!PCI Rev. 2.2 compliant with support for 33MHz PCI operations
!Supports up to 6 Req/Gnt pairs (PCI Slots), WB6 already share one Req/Gnt signal for

1-2 Chapter1
WB6
PCI audio chipset.
!Integrated IDE controller with Ultra DMA/66 support
!USB host interface with support for 2 USB ports
!AC '97 2.1 compliant link for audio and telephony CODECs
!Firmware Hub (FWH) interface support
The FW82802AB is also called the FWH, Firmware Hub. The FWH component is part of
several integrated Intel®chipsets. The FWH is key to enabling future security and
manageability infrastructures for the PC platform. The device operates under the FWH
interface/protocol. The hardware features of this device include a Random Number
Generator (RNG), five General Purpose Inputs (GPIs), register-based block locking, and
hardware-based locking. An integrated combination of logic features and non-volatile
memory enables better protection for the storage/update of platform code/data, adds
platform flexibility through additional GPIs and allows for quicker introduction of new
security/manageability features into the current and future Intel®architecture platform. It's
available in 8Mbit (82802AC), 4Mbit (82802AB), and 2Mbit (82802AA) densities. It uses
the 32L PLCC or 40L TSOP industry standard packages.
The WB6 has one AMR slot onboard, it is called the Audio/Modem Riser (AMR) slot. The
Audio/Modem Riser is an open industry-standard specification that defines a hardware
scalable Original Equipment Manufacturer (OEM) motherboard riser board and interface,
which supports both audio and modem functions. The specification's main objective is to
reduce the baseline implementation cost of audio and modem functionality. In accordance
with PC user's demands for feature-rich PCs, combined with the industry's current trend
towards lower cost PCs, all of theses functions are built into the motherboard. But
motherboard integration of the modem subsystem hasbeen problematic to date, in large part
due to FCC and other international telecom certification processes that may delay the
introduction of a motherboard. Resolving the homologation/certification issue for modems
is one of the AMR specification's key objectives.
In the future, not only OEM motherboards will have an AMR design, the AMR card will
appearin themarketand you can makea choiceinbuying this kind of card accordingto your
budget. But your motherboard must have an AMR slot to be able to plug an AMR card. The
WB6 insures this expandibility for this issue.
Y2K Problem Free
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.

Introduction of WB6 Features 1-3
User's Manual
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.

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.

2-2 Chapter2
WB6
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 that shows the studs and spacers, theymay have several types, but
all look similar to 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.

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. This
motherboard also supports the Celeron®PPGA processor. If you want to install the Celeron®
PPGA processor, you have to use an additional adapter that allows you to use a Celeron®
PPGA processor in a slot 1 board. For this ABIT makes the SlotKETadapter.
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.

2-4 Chapter2
WB6
2-3. Installing System Memory
This motherboard provides two 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 (512MB using 128Mb technology).
There are two memory module sockets on the system board. (total four banks)
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
(DIMM1) 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 8MB ~ 256MB
Bank 2, 3
(DIMM2) 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 8MB ~ 256MB
Total System Memory 8MB ~ 512MB
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 showyou 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.

Installing the Motherboard 2-5
User's Manual
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 thenext 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.
