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 P6BA-A+ mainboard has a power connector for an ATX power supply. Ensure
that your system is installed with an ATX power 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-A+ 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.

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.
Preparing the Mainboard
Prepare the mainboard by installing the supplied Pentium-II retention module. Then
install the Pentium-II cartridge according to the instructions supplied with the
cartridge. Complete the processor installation by installing the supplied heat-sink
support, and connecting the heat sink power cable to the mainboard connector.
After the processor cartridge is installed, insert your memory modules into the DIMM
sockets on the mainboard. Finish the mainboard preparation by checking that all the
mainboard jumpers are at the correct setting.

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 CPUFAN.
Note: The P6BA-A+ 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)
(SDRAM). This mainboard can support 100MHz SDRAM and also 66MHz SDRAM.
We recommend that you use 100MHz SDRAM with PC/100 compatibility so that
your system can run at the maximum speed.
The DIMMs can hold memory capacities from 8 MB through to 128 MB. You can
install one, two or three DIMMs in any combination. up to 384 MB of standard
SDRAM. Install the first DIMM in the DIMM1 socket. If you install a second or third
DIMM, install them in DIMM2 and DIMM3 respectively.
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 Jumper Settings
This mainboard only has three jumpers. For most systems the factory defaults will be
the correct configuration. Before you install the mainboard, take a moment to check
that the three jumpers are at the correct setting.
1. Locate the Clear CMOS jumper JP1. 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 power cord disconnected.

2. Locate the Keyboard Power On Switch jumper JP2. When this jumper is enabled,
it allows you to create “hot keys” on your system keyboard that will act as a
power On/Off switch. See the Integrated Peripherals Option in the Setup chapter
for information on installing this function. As a default, the keyboard power
switch is enabled. When you have enabled Keyboard Power On, you must ensure
that the 5V standby current of the power supply is more than 200 mA.

Install the Mainboard in the System Case
Use the screws and mounting brackets supplied with your system case to install the
mainboard. Follow the instructions provided by the case manufacturer.
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. There is no key on the mainboard connector
however, so you must manually ensure that the cable is installed correctly.
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.

4. Locate the ATX POWER connector. 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 AGP slot. You can use the two ISA slots, and the five PCI slots to
install a variety of expansion cards in your system, such as a sound card, a
network adapter, a SCSI host adapter, an internal modem card, and so on. ISA slot
1 and PCI slot 5 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 a serial or fast 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) and FIR1 (Fast Infrared).
Determine if your infrared port is SIR or FIR and use the cable provided with the
Page 14

infrared device to connect to the correct connector. Secure the infrared device to
USB1
LPT1
COM1
COM2
the appropriate space in the system case.
2. If you have installed a network adapter, connect the cable from the network
adapter to 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 WOM1. This will enable your system to resume from a power saving
mode when there is modem traffic.
4. If you have installed a Creative PCI Sound Blaster card, you can cable it to the
SB-Link connector SIDEBAND1. The SB-Link connector provides a PCIcompatible solution that allows your Sound Blaster to run real-mode DOS game
applications.
5. 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 PWRFAN3. If you
have a case mounted fan, you can connect it to the case cooling fan power
connector CASEFAN1.
6. If your case supports a detector that indicates when the case is opened, you can
connect the cable to the case open detect connector CASEOPEN1.
Part Three – External Connections
After you have installed the mainboard and completed the internal connections, you
can use the external connectors to attach peripheral devices to your system
KBMPS2
1. COM1 is a serial port which can be used by serial devices such as a mouse, a
fax/modem and so on. Your system identifies this serial port as COM1
2. COM2 is a second serial port. Your system identifies this serial port as COM2.
3. LPT1 is a parallel port which can be used by printers or other parallel
communications devices. Your system identifies the parallel port as LPT1
4. USB1 is a stack of two universal serial bus (USB) ports. Some new devices now
use the USB interface to take advantage of its faster transmission, and the fact that
many devices can be “daisy chained” on a single cable.
5. KBMPS2 is a stack of two mini-DIN PS/2 ports. The lower port is for the use of a
keyboard. The upper port can be used by any PS/2 pointing device such as a
mouse or a trackball.

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
You can only start the setup utility shortly after the computer has been turned on. A
prompt appears on the computer display which says “Press DEL to run Setup” . When
you see this prompt, press the Delete key, and the system will start the setup utility
and display the main menu of the utility.
Using the Setup Utility
When you press the Delete key to start setup, the main menu of the utility appears.
The main menu of the setup utility shows a list of the options that are available in the
utility. A highlight shows which option is currently selected. You can use the cursor
arrow keys to move the highlight to other options. When an option is highlighted, you
can execute the option by pressing the Enter key.
Some options lead to dialog boxes which ask you verify that that you wish to execute
that option. You usually answer these dialogs by typing Y for yes and N for no.
Some options lead to dialog boxes which ask for more information. Setting the User
Password or Supervisor Password have this kind of dialog box.
Page 16
13
Some options lead to tables of items. These items usually have a value on the right
side. The value of the first item is highlighted, and you can use the cursor arrow keys
to select any of the other values in the table of items. When an item is highlighted, you
can change the value by pressing the PageUp or PageDown keys, or the Plus or
Minus keys. The PageUp and Plus keys cycle forward through the available values,
the PageDown and Minus keys cycle backwards through the values.
When you are in the main menu, you can exit the utility by pressing the Escape key.
You can save the current selections and exit the utility by pressing the F10 key. You
can change the color scheme of the utility by pressing the F2 key while holding down
the Shift key.
When you are in one of the options that displays a dialog box, you can return to the
main menu by pressing the Escape key.
When you are in one of the options that displays a table of items, you can return to the
main menu by pressing the Escape key. For some items, you can display a help
message by pressing the F1 key. You can change the color scheme of the utility by
pressing the F2 key while holding down the Shift key. You can press F5 to discard
any changes you have made and return all items to the value that they held when the
setup utility was started. You can press F6 to load the displayed items with a standard
list of default values. You can press F7 to load the displayed items with a highperformance list of default values.
Page 17

Standard CMOS Setup Option
This option displays a table of items which defines basic information about your
system.
Date and Time
The Date and Time items show the current date and time held by your computer. If you are
running a Windows operating system, these items will automatically be updated whenever
you make changes to the Windows Date and Time Properties utility.
Hard Disks Defaults: Auto
These items show the characteristics of any hard disk drives on the four available IDE
channels. (Note that SCSI hard disk drives do not appear here.) You can automatically
install most modern hard disks using the IDE HDD Auto Detect Option from the main
menu. However, if you find that a drive cannot be automatically detected, you can use
these items to select USER, and then manually enter the characteristics of the drive. The
documentation provided with your drive provides the data you need to fill in the values for
CYLS (cylinders), HEAD (read/write heads), and so on.
The documentation provided with the drive may not tell you what value to use under the
MODE heading. If the drive is smaller than 528 MB, set MODE to Normal. If the drive is
larger than 528 MB and it supports Logical Block Addressing, set MODE to LBA. Very
few high-capacity drives do not support Logical Block Addressing. If you have such a
drive, you might be able to configure it by setting the MODE to Large. If you’re not sure
which MODE setting is required by your drive, set MODE to Auto and let the setup utility
try to determine the mode automatically.
Drive A and Drive B Default: 1.44M, 3.5 in., None
These items define the characteristics of any diskette drive attached to the system. You can
connect one or two diskette drives.
Page 18
15
Floppy 3 Mode Support Default: Disabled
Floppy 3 mode refers to a 3.5” diskette with a capacity of 1.2 MB. Floppy 3 mode is
sometimes used in Japan.
Video Default: EGA/VGA
This item defines the video mode of the system. This mainboard has a built-in VGA
graphics system so you must leave this item at the default value.
Halt On Default: All Errors
This item defines the operation of the system POST (Power On Self Test) routine. You can
use this item to select which kind of errors in the POST are sufficient to halt the system.
Base, Extended and Other Memory.
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: 233 MHz or 350MHz
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.
Page 19
16
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).
Page 23
20
Power Management Default: User Define
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-saving modes are disabled. If this item is set to
Max Saving, doze, standby, and suspend mode, will occur after a timeout of 20 seconds. If
this item is set to Min Saving, doze, standby, and suspend mode will occur after a timeout
of 40 minutes. If the item is set to User Define, you can insert your own timeouts for the
power-saving modes.

If you would like an incoming call on a modem to automatically resume the system from
suspend mode, use this item to specify the interrupt request line (IRQ) that is used by the
modem.
Soft-Off by PWRBTN Default: Delay 4 sec
Under ACPI (advanced configuration and power interface) the system can be turned off
mechanically (by the power button) or it can undergo a software power off. If the system
has been turned off by software, the system can be resumed by a LAN, MODEM or
ALARM wake up signal. This item allows you to define a software power off using the
power button. If the value is set to Instant-Off, the power button will automatically cause a
software power off. If the value is set to Delay 4 Sec. the power button must be held down
for a full four seconds to cause a software power off.
HDD Power Down Default: Disabled

to ON, the all the following interrupts can be manually configured to act as resets for the
power saving timeouts. If this item is set to OFF, then all the following interrupt items
cannot be used to reset the power saving timeouts.
IRQX
These interrupt events can act as triggers to reset the power saving timeouts or other
system maintenance tasks. If you set an interrupt event to Primary, any activity on that
interrupt will reset the timeouts that use the primary timer (e.g. the power saving modes). If
you set an interrupt to Secondary, then any activity on the interrupt will reset those
timeouts that use the secondary timer (usually background maintenance tasks). If you set
an interrupt event to Disabled, any activity on the interrupt will not reset the timeouts.
PNP/PCI Configuration Option
This option displays a table of items that configures how PNP (Plug and Play) and PCI
expansion cards operate in your system.
