Chapter 2 Installing the Motherboard
This BX6 motherboard not only provides all standard equipment for classic
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PentiumII/III processors and Intel
Celeronprocessor now on the market. (For details, see specifications in
Chapter 1.)
This chapter is organized according the following features:
(1) Installing the Motherboard to the Casing
(2) Standard external connectors
(3) Jumpers and switches
(4) Installation of the PentiumII/III, CeleronCPU
(5) Installing the system memory

Before proceeding with the installation
Before installing the motherboard please be sure to turn off or disconnect the
power supply unit. Before making any modifications to the hardware
configuration of the motherboard, the power supply to any areas of the
motherboard you plan to modify should be turned off to avoid unnecessary
damage to the hardware.
&
User friendly instructions
Our objective is to enable the novice computer user to perform the installation by
themselves. 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.

Chapter 22-2
(1) Installing the Motherboard to the Casing
Most computer cases 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.
lwith spacers
lor with bolts
Please refer to the figure below that shows the studs and spacers, they may have
several types, but all look like the figures below:
Figure 2-1. The outline of stud and spacer
In principle, the best way to attach the motherboard is with bolts, 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 bolts. 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 it 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.
Note: If the motherboard has mounting holes, but don’t line up with the holes on the base and
their are no slots to attach the spacers, don’t worry, you can still attach the spacers to
the mounting holes. Just cut the spacers (along the dotted line) (the spacer may be a
little hard so be careful of our hands). In this way you can still attach the motherboard
to the base without worrying about short circuits.

(2) Standard External Connectors
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.
PN1(Pin 1-2-3-4-5): Keylock and Power LED Header
There is a specific orientation for pin 1 through pin 5. Insert the two-threaded
keylock cable into pin 4 and pin 5, and three-threaded power LED cable to Pin 1
~ pin 3. Check to make sure the correct pins of connector on the motherboard.

RT2 Header (Optional)
This header is for you to connect an additional thermistor to detect the CPU
temperature. You can buy the thermistor at an electronics store, and ask for a
10KΩthermistor which will be OK. Please don’t use too long of a lead wire for
the thermistor. You can see the detected temperature in the BIOS menu. (see
Chipset Features Setup Menu)
According to ACPI specifications, CPU fan speed is relative to the CPU
temperature. In order to avoid confusing ACPI functions, we strongly suggest that
you connect the additional thermistor to the CPU.
Note: 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 power
cord off. Otherwise, you may cause the motherboard components, add-on cards to
malfunction or be damaged.

(3) Jumper and Switches
You can set jumper switches on the motherboard to configure various hardware
options. See Figure 1-1 for jumper locations.
Throughout this section, the following symbols are used to indicate jumper
settings.
For 3-pin jumpers, the symbols below are used:
For 2-pins jumpers, the following symbols are used:
Note: To avoid losing jumper caps, attach the removed jumper cap to one of the jumper pins.
Short Pins 1 and 2 with a jumper cap.
Short Pins 2 and 3 with a jumper cap.
Place the jumper cap over the two pins of the
jumper to Short the jumper.
Remove the jumper cap to Open the jumper cap.

CCMOS 1 : CMOS Discharge Jumper
Jumper CCMOS discharge CMOS memory. When you install the motherboard,
make sure this jumper is set for Normal Operation (1-2). See the jumper below.

II/III, Celeron

CPU
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:
lInstalling 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.
lPlease refer to your boxed processor installation or other documentation attached with
your CPU for detailed installing instructions.

Chapter 22-12
(5) Installing System Memory
The motherboard provides four 168-pin DIMM sites for memory expansion.. The
DIMM socket supports 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 1GB
SDRAM.
There are four Memory module sockets on the system board.(Total eight 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. (Without parity or with parity)
lThose modules can be populated in any order.
lSupport single and double density DIMMS.
The following is the valid memory configuration:
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 4, 5
(DIMM3) 8MB, 16MB,32MB, 64MB, 128MB, 256MB 8MB ~ 256MB
Bank 6, 7
(DIMM4) 8MB, 16MB,32MB, 64MB, 128MB, 256MB 8MB ~ 256MB
Total System Memory 8MB ~ 1GB
