Hardware Installation
This chapter gives you a step-by-step procedure on how to install your
system. Follow each section accordingly.
2.1 ESD Precautions
Electrostatic discharge (ESD) can damage your processor, disk drives,
expansion boards, and other components. Always observe the following
precautions before you install a system component.
1. Do not remove a component from its protective packaging until you are
ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit
before handling a component. If a wrist strap is not available, maintain
contact with the system unit throughout any procedure requiring ESD
protection.

2.4 Installing a Microprocessor
The motherboard comes with a ZIF microprocessor socket that allows you to
install a CPU without using any tool.
Follow these steps to install a CPU into a ZIF-type CPU socket:
Make sure that the system power is OFF before
installing a component.
1. Locate the CPU socket on the
system board and pull up the
socket lever.
2. Align pin 1 of the CPU with hole 1
of the socket. The dot on the CPU
indicates pin 1. The topmost label
indicates the CPU frequency and
the cache size.

2.6 Configuring the System Memory
The system memory is expandable to 512 MB by adding single in-line
memory modules (SIMMs). The four 72-pin SIMM sockets accommodate
4-, 16- and 64-MB single-density SIMMs, and 8- and 32-MB double-density
SIMMs. These SIMM sockets also accept both FPM and EDO type DRAMs,
with or without parity. The EDO feature extends the data transfer cycle, thus
improves memory performance. All SIMMs support a DRAM speed of 60/70
ns or less.
The SIMMs with parity supports the ECC (Error Checking and Correction)
feature that enables the system to detect and correct data errors. To fully
support this function, you must install 36-bit parity-type SIMMs (i.e., 8 chips
plus 4 parity chips) in pairs in all banks. The combination of 32-bit non-parity
(i.e., 8 chips) and 36-bit parity-type (i.e., 12 chips) memory configuration is
also possible; however, this does not allow you to make use of the ECC
function.
The following are the possible SIMM configurations. Notice that you must
install the same SIMMs in one bank.
Memory Configurations

Make sure that you install the same SIMM type for each
bank.
Do not install memory modules that contain more than
24 chips. These modules exceed the ASIC
specification. Doing so may result in unstable system
performance.
2.6.1 Installing a SIMM
Observe the ESD precautions when installing
components.
Follow these steps to install a SIMM:
1. Slip a SIMM at a 45 ° angle into a
socket. If the SIMM does not
completely fit into the socket,
reverse the SIMM orientation. The
SIMM has a curved edge indicating
pin 1 that ensures installation in
one direction only.
Be careful when inserting or removing SIMMs.
Forcing a SIMM in or out of a socket can
damage the socket or the SIMM (or both).
Hardware Installation
curved edge
2. Gently push the SIMM up until the
pegs of the socket slip into the
holes on the SIMM and the holding
clips lock the SIMM into a vertical
position.
The SIMM should be at a 90 angle when
installed.

2.6.2 Removing a SIMM
To remove a SIMM:
1. Press the holding clips on both
sides of the SIMM outward to
release it.
2. Press the SIMM downward to
about a 45° angle.
3. Gently pull the SIMM out of the
socket.

2.7 Customizing your Hardware Setup
You may customize your hardware setup according to your desired system
performance. However, doing so requires resetting of several jumpers. The
onboard jumpers are normally set to its default setting. See the figure in
section 2.2 for the location of the jumpers on the system board.
The following sections tell how to configure the system board to meet the
desired performance:
2.7.1 Setting the Voltage Regulator
The jumper JP1 enables you to set the voltage of the onboard voltage
regulator. The supported voltage range is from 2.1V to 3.5V. See the
following figure for the correct settings.
Voltage JP1 Voltage JP1
*
Auto *
3.5V
3.4V
3.3V
3.2V
3.1V
3.0V
2.9V
* The system can automatically detect the CPU volltage through the VID pins; therefore,
by default, JP1 is set to OPEN. You do not need to set the voltage regulator setting.

2.7.2 Disabling the Onboard Super I/O Controller
The board is preset by the manufacturer
with the onboard I/O controller enabled.
In case you wish to use an external I/O
controller, you need to disable the
onboard I/O before the external I/O card
functions. To disable, you need to reset
jumper JP6 to 1-2.

Disabled
2.7.3 Setting the Keyboard Clock
By default, the keyboard clock is set
according to the ISA clock. If you want
to increase the clock setting to 12 MHz
by simply resetting jumper JP7 to 1-2.

2.7.4 Disabling the PS/2 Mouse Function

The PS/2 mouse function is normally
enabled and occupies IRQ12. To
reassign IRQ12 to another function, you
need to disable the PS/2 mouse function
by setting jumper JP8 2-3 and changing
the BIOS setting (see Chapter 3).

Hardware Installation
2.7.5 Enabling the Intel Flash ROM Boot Block
Programming
The Intel Flash ROM has two areas that
can be programmed separately: the
8KB boot block and the 120KB main
BIOS area.
The jumpers JP11 and JP12 allow you
to program the Flash ROM boot block.
By default, the boot block program
function is enabled and both JP11 and
JP12 are set to 1-2.
Enabled (default)
Reserved
The jumper setting shown above applies only
for Intel Flash ROM.
Do not change the default setting of JP11
and JP12. Doing so modifies the main BIOS
area but not the boot block, causing the
BIOS to become inconsistent. This may
result in serious system damage.
2.7.6 Selecting the Power Switch Type
The jumper JP14 allows you to set the
power switch type that you want to
support, i.e., either the toggle type or the
momentary type. However, before you
set this jumper, make sure that you
know your power switch type.
JP14
Toggle type switch
Momentary type switch
JP11 JP12
2-13
Hardware Installation
To differentiate a toggle type from a momentary type, check the On and Off
switch position. In a toggle type switch, a pressed switch indicates On
position while a normal switch position indicates Off. In a momentary type,
the switch position does not change for both modes.
To support a toggle type switch, close pins 2-3 of JP14. Close all pins (1-4)
to support a momentary type switch.
2.7.7 Clearing the CMOS
You need to clear the CMOS if you forget your system password. To clear the
CMOS, do the following steps:
Before you proceed, check your onboard CMOS
chip. The learing procedures vary depending
on the CMOS chip type. Read the CMOS chip
label to determine the chip type.
For Dallas DS12887A:
1. Turn off the system power.
2. Locate JP10 and short pins 1-2 for
a few seconds. Check your manual
for the correct jumper settings and
location of the jumpers.
3. Reset JP10 to its normal setting by
shorting pins 2-3.
4. Turn on the system power.
5. Press
the BIOS Setup Utility and specify a
new password, if needed.
