Features

The P6BX-Me mainboard features a slot-1 Pentium-II processor socket and support
for a 100 MHz system bus, plus backward compatible support for a 66 MHz system.
This means that the mainboard will support the first generation of Pentium-II
processors (clocking from 233 MHz up to 333 MHz) and also the latest generation of
Pentium-II processors (clocking from 350 MHz to 450 MHz and beyond).

The P6BX-Me also has an accelerated graphics port (AGP), built-in PCI stereo sound
system and three usable expansion slots. In short, the P6BX-Me is a very flexible
mainboard that supports a wide range of performance options from low-cost Celeron
through to the most powerful PC processor available from Intel.

Selectable Performance

The combination of a slot-1 Pentium-II socket and support for both 66 MHz and 100
MHz system bus means that this system will support all variations of the Pentium-II
processor. As well as the low-cost Celeron processor (with no level 2 cache), the board
can support the following Pentium-IIs; 233/66, 266/66, 300/66, 333/66, 350/100,
400/100, and 450/100. This board can be configured for entry-level, small office/home

3

office, mainstream business, and power user performance levels. Changing processor
configurations is easily accomplished using firmware settings.

Highly Integrated Design

The system features a high degree of integration based on the Intel 440BX chipset.
The Intel 440BX chipset comprises the 82443BX AGPset and the 82371EB PCIset.
Together they provide the system logic for the Pentium-II board with 66 MHz or 100
MHz system bus. Support for a Rev. 1 compliant AGP graphics adapter is provided. In
addition, the chipset enables Ultra DMA bus-mastered PCI IDE channels, USB ports,
Error Correction Code (ECC) memory modules, and ACPI (advanced configuration
and power management interface) functions.

Keyboard Power On Option

Using the system BIOS settings, you can configure the system to turn on using
keyboard hot keys or password. A green keyboard is not required.

Three Memory Sockets

Unlike many competing ATX-micro mainboards, this board has sockets for three
SDRAM memory modules. The sockets support 3.3V 168-pin SDRAM memory
modules which can be PC-100 compliant, using a 100 MHz memory bus, or using a 66
MHz memory bus. With standard SDRAM, each socket can support a module with 8,
16, 32, 64, or 128 MB for a maximum capacity of 384 MB. Using Registered SDRAM,
the capacity can be doubled to a maximum of 768 MB. The sockets will support
memory that has no error correction, memory with EC (error correction) and memory
with ECC (error correction code).

Four Usable Expansion Slots

The board has a total of five expansion slots; one AGP slot for an accelerated graphics
port display adapter, two 32-bit PCI slots, and two 8/16-bit ISA slots. However, one of
the PCI slots is shared with one of the ISA slots so that only one of the slots can be
used at any one time. Since this mainboard has integrated audio, two built-in IDE
channels and a floppy disk interface, plus a full set of I/O ports including two USB
ports, four usable expansion slots provide enough potential for full system expansion,
such as the addition of a network adapter, a fax/modem and so on.

Integrated I/O Ports

The board features a full set of I/O ports – PS/2 keyboard, PS/2 mouse, parallel, two
serial, two USB, Game/MIDI, and audio jacks for stereo in, stereo out, and
microphone. Optionally, an infrared port can be installed as an alternative to the
second serial port. The ports are arranged in a two-tier array which is supported by
standard ATX I/O templates.

4

Built-in PCI Audio

The built-in PCI audio chip provides a full duplex sound system that is compatible
with the Sound Blaster and Windows Sound standards. It allows simultaneous
recording and playback, and can record at CD-quality sampling rates of 44 kHz.

Programmable Firmware

The mainboard includes Award BIOS which allows BIOS setting of CPU parameters.
The fully programmable firmware enhances the system features and allows users to set
power management, hardware monitoring (optional), LAN and Modem wake up
alarms, and so on.

Optional Hardware Monitoring

The Winbond W83781D hardware monitoring chip can be specified as a factory
installed option. This chip can provide hardware monitoring of critical internal
temperatures and voltages. This option is useful for large scale network administration
and diagnostic routines. The optional thermal detector, which interacts with the
W83781D monitoring chip, gives accurate information on the actual temperature of
the Pentium-II processor module in Slot-1. This option is useful for large-scale
network administration and diagnostic routines.

Before You Begin

Before you begin to install your P6BX-Me mainboard, take some precautions to
ensure that you avoid the possibility of damage to the product from static electricity.
Ensure too that you are installing the mainboard into a suitable case.

Static Electricity

In adverse conditions, static electricity can accumulate and discharge through the
integrated circuits and silicon chips on this product. These circuits and chips are
sensitive and can be permanently damaged by static discharge.

♦ If possible wear a grounding wrist strap clipped to a safely grounded device

during the installation.

♦ If you don’t have a wrist strap, discharge any static by touching the metal case

of a safely grounded device before beginning the installation.

♦ Leave all components inside their static-proof bags until they are required for

the installation procedure.

♦ Handle all circuit boards and electronic components carefully. Hold boards by

the edges only. Do not flex or stress circuit boards.

Choosing a Case

The P6BX-Me mainboard has a power connector for an ATX power supply. Ensure
that your system is installed with an ATX power unit. The mainboard complies with
the specifications for the micro-ATX system case, although it can also be installed in
most full-size ATX case designs. The micro-ATX specifications include a maximum
size of 9.6” x 9.6” (244mm x 244mm), a reduced number of expansion slots, and
support for a smaller power supply unit.

Some features on the mainboard are implemented by cabling connectors on the
mainboard to indicators and switches on the system case. Ensure that your case
supports all the features required. The P6BX-Me mainboard can support one or two
floppy diskette drives and four enhanced IDE drives. Ensure that your case has
sufficient power and space for all the drives that you intend to install.

2. Some cartridge holders also include a support bar for the heat sink. This bar

installs to the side of the cartridge holder. Some Pentium-II processors have
support struts for the heat sink which lock into the support bar. The
documentation with the Pentium-II processor shows how to do this.

3. Follow the instructions given with your Pentium cartridge to install the processor

cartridge into the cartridge holder.

4. If necessary, connect the power cable from the cartridge cooling fan to the

mainboard CPU fan power supply CPU FAN.

Note: The P6BX-Me does not use jumpers to set the parameters for your
processor, such as the core voltage, the clock multiplier, and so on. You can set
the parameters for the processor in firmware using the system BIOS. After your
system is installed, the BIOS will automatically detect the kind of processor
that is installed and implement the correct setting for it. See the next chapter
for details.

Install the Memory Modules

For this mainboard, you must use 168-pin Dual In-line Memory Modules (DIMMs)
which are installed with SDRAM (Synchronous Dynamic Random Access Memory).
This mainboard supports 3.3 volt DRAMs operating over a 66 MHz memory bus, and
it will also support PC-100 compliant memory which operates over a 100 MHz
memory bus. If you are installing a processor which runs using a 100 MHz bus, you
must use PC-100 compliant memory.

You can install one, two or three modules, and each module can have a capacity of up
to 128 MB for standard SDRAM. If you use registered DRAM, the capacity of the
modules can be doubled to 256 MB. All the memory modules that you install must be
of the same kind. If you only install one memory module, install it in DIMM socket 1.
If you install two modules, install them in DIMM sockets 1 and 2.

1. The SDRAM sockets are keyed with notches and the DIMMs are keyed with cut-

outs so that they can only be installed correctly. Check that the cut-outs on the
DIMM edge connector matches the notches in the SDRAM socket.

2. Push the latches on each side of the SDRAM socket down.

3. Install the DIMM into the socket and press it carefully but firmly down so that it

seats correctly. The latches at either side of the socket will be levered upwards
and latch on the edges of the DIMM when it is installed correctly.

Check the two Jumper Settings

This mainboard only has two jumpers. For most systems the factory defaults will be
the correct configuration. Before you install the mainboard, take a moment to check
that the two jumpers are at the correct setting.

10

A Note on Jumpers

A jumper consists of two or more pins mounted on the mainboard. Some
jumpers might be arranged in a series with each pair of pins numbered
differently. Jumpers are used to change the electronic circuits on the
mainboard. When a jumper cap is placed on two jumper pins, the pins are
SHORT. If the jumper cap is removed (or placed on just a single pin) the pins
are OPEN.

1. Locate the Keyboard Power On Enable/Disable jumper JP1. This jumper lets you

set KB power source is standby voltage of 5V or Vcc. The standby voltage of 5V
is required if you want to use the keyboard power on feature. The keyboard power
on feature can be turned on using the system BIOS. See the next chapter for more
information.

2. Locate the Clear CMOS jumper JP3. Ensure that the jumper cap is placed on pins

1-2. If you ever need to clear the system CMOS memory, you can do this by
moving the jumper cap to short pins 2-3 for a few seconds. When you clear the
CMOS memory, the system must be turned off and the ATX power supply cable
must be disconnected from the ATX power connector on the mainboard.

Connect Devices, Switches and Indicators to the Mainboard

Note: You might not need to carry out every step in the following procedure. It
depends on the options you are installing, and the features that are supported
by your system case.

Note: Ribbon cables are usually keyed so that they can only be installed
correctly on the device connector. Each connector has the pin-1 side clearly
marked. The pin-1 side of each ribbon cable is always marked with a red stripe
on the cable.

Part One – Internal Connections

1. Locate the floppy diskette drive connector FDD1. Use the ribbon cable to connect

the floppy diskette drive to the mainboard.

2. Locate the Enhanced IDE connectors IDE1 (primary) and IDE2 (secondary). A

single IDE cable is provided with the mainboard. Connect the cable to IDE1 The
cable has two connectors for IDE devices. If you connect two devices, you must
configure one device as Master, and one device as Slave. See the documentation
provided with the devices for information on this. If you need to install more
drives, obtain another IDE cable and connect one or two devices to IDE2
following the same procedure as you used with IDE1.

3. Locate the bank of switch and indicator connectors PANEL1. These connectors

provide control functions to your system case. Use the illustration below and the
following table to make the connections.

4. Locate the ATX power connector ATX1. Connect the cable from your system

ATX power supply into the connector. The connector is keyed so that it can only
be installed correctly.

5. Install expansion cards into the expansion slots. The system will not operate

without a display adapter. If you have an AGP display adapter, you can use the
dedicated AGP1 slot. You can use the two ISA slots, and the two PCI slots to
install a variety of expansion cards in your system, such as a network adapter, a
SCSI host adapter, an internal modem card, and so on. ISA slot 1 and PCI slot 2
are shared. This means that you can use one of these slots, but not both of them at
the same time.

Part Two – Optional Internal Connections

You may install optional items such as an infrared port. If you have installed a
network adapter or an internal modem, you can use the wake-up connectors so that
your system will automatically resume from a power-saving mode when there is
incoming network or modem traffic.

1. Locate the infrared connector SIR1 (Standard Infrared). Use the cable provided

with the infrared device to connect to the IR connector. Secure the infrared device
to the appropriate space in the system case.

Note: If you install an infrared port, it must share a COM port assignment with
the second external serial port COM2. You can select which port is in use by
using the setup utility.

2. If you have installed a network adapter, connect the cable from the network

adapter to the Wake on LAN connector WOL1. This will enable your system to
resume from a power saving mode when there is network traffic. When you use
the LAN wake up function, you must make sure that the 5V standby current from
the power supply is more than 700mA.

3. If you have installed an internal modem,.connect the cable from the internal

modem to the Wake on Modem Connector WOM1. This will enable your system
to resume from a power saving mode when there is an incoming call to the
modem.

4. You may install extra cooling fans. Some ATX power units have a cooling fan.

You can connect this to the ATX cooling fan power connector POWER FAN. If
you have a case mounted fan, you can connect it to the case cooling fan power
connector CHASSIS FAN.

5. If you install a CD-ROM drive in your system, you can connect the audio output

of the CD-ROM drive to the audio system integrated on the mainboard. Connect
the CD-ROM drive audio cable to the CD-audio connector CD-IN. If the
connector from the CD-ROM is not compatible with CD-IN, you can use the
auxiliary CD-audio connector J6.

About the Setup Utility

This chapter explains how to use and modify the BIOS setup utility that is stored on
the mainboard. The setup utility stores information about the mainboard components,
and the configuration of other devices that are connected to it. The system uses this
information to test and initialize components when it is started up, and to make sure
everything runs properly when the system is operating.

The setup utility is installed with a set of default values. The default values are
designed to ensure that the system will operate adequately. You will probably have to
make changes to the setup utility whenever you add new components to your system
such as new disk drives. You may be able to generate increased performance by
changing some of the timing values in the setup, but this can be limited by the kind of
hardware you are using, for example the rating of your memory chips. In certain
circumstances, the system may generate an error message which asks you to make
changes to the setup utility. This happens when the system finds an error during the
POST (power on self test) that it carries out at start up.

Starting the Setup Utility

These items show how much memory is available on the system. They are automatically
detected by the system so you cannot manually make changes to these items.

BIOS Feature Setup Option

This option displays a table of items which defines more advanced information about
your system. You can make modifications to most of these items without introducing
fatal errors to your system.

CPU Internal Core Speed Default: 350 MHz

This item should be installed with the rated internal core speed of the Pentium-II class
processor that is installed in your system. The setup utility will then automatically
configure the system with the correct host bus speed, and bus frequency multiplier.

If you set this item to Manual, two new items will appear: CPU Host BUS Frequency and
CPU Core:Bus Freq. Multiple. You can use these two items to manually configure the
mainboard for the speed of the processor. The values available in these two items will vary,
according to the kind of Pentium-II processor that is installed.

18

Note: Using the three items above, you can configure the mainboard so that it
runs a processor faster than the rated clock speed. We strongly recommend
that you do not overclock the processor. Overclocking can introduce excess
heat, recurring instability, or even complete failure in your system.

Virus Warning Default: Disabled

When this item is enabled it provides some protection against viruses which try to write to
the boot sector and partition table of your hard disk drive. This item is disabled as a default

Power Management Setup Option

This option displays a table of items which lets you control the power management of
the system. Modern operating systems take care of much of the routine power
management. This mainboard supports ACPI (advanced configuration and power
interface).

This system supports three levels of power-saving modes; doze mode, standby mode,
and suspend mode. Standby mode uses less power than doze mode and suspend mode
uses the least power.

The power management in the setup utility lets you specify a timeout for each of the
power-saving modes, and a timeout for a hard disk drive power down. A timeout,
means a period of time when the system (or the hard disk drive) is inactive. If the
timeout completes, the system power-saving mode will execute, or the hard disk drive
will power down. You can resume from the power-saving modes by carrying out any
of the activities which are enabled in the list **Reload Global Timer Events**. If the
hard disk has been powered down it will automatically resume to full power when an
access to the hard disk is required (this takes just a few seconds).

22

ACPI function Default: Enabled

ACPI stands for Advanced Configuration and Power Interface. This mainboard supports
this function so leave this item at the default value Enabled.

Power Management Default: Min Saving

This item acts like a master switch for the power-saving modes and hard disk timeouts. If
this item is set to Disabled, all the power-savings modes are disabled. If this item is set to
Max Saving, doze, standby, and suspend mode, will occur after a very short timeout. If this
item is set to Min Saving, doze, standby, and suspend mode will occur after a long timeout.
If the item is set to User Define, you can insert your own timeouts for the power-saving
modes.

Video Off Method Default: V/H SYNC+Blank

This item defines how the video is powered down to save power. As a default, this is set to
V/H SYNC+Blank.

Video Off Option Default: Standby

This option defines which level of power-saving mode is required in order to power down
the video display. As a default, the video powers down in both suspend mode and standby
mode.
