Chapter 2
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 zero-insertion force 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 Voltage Regulator Module
You must install the CPU first before installing
the VRM. See the section 2.4 on how to install
a CPU.
The system board comes with a separate voltage regulator module that
enables the system to support the processor operating voltage ranging from
2.1V to 3.5V. The following sections tell how to install and remove VRM.
2.6.1 Installing VRM
Observe the ESD precautions when installing
components.
Follow these steps to install a VRM:

2.7 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 Fast Page type and Extended
Data Output (EDO) type DRAMs. 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 following are the possible SIMM configurations. Notice that you must
install the same SIMMs in one bank.

2.7.1 Installing a SIMM
Observe the ESD precautions when installing
components.
Memory
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.
2-12
curved edge
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).
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 90angle when
installed.
2.7.2 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.

2.8 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:
2.8.1 Selecting the IR Module Type
The connector marked CN13 lets you
select the Infrared (IR) module type that
you wish to install. The IR module
enables the system to support the remote
115.2 Kbit (5V)
4 Mbit (3.3V)
file transfer function.
2.8.2 Selecting the ECP DMA Channel
The ECP DMA channel selections depend
on the onboard I/O controller. The board
may come either with SMC 665 or SMC
669 I/O controller. If you have SMC 665
controller, then you may set a DMA
channel for the ECP function. The
selections are channels 3 and 1. The
default is DMA channel 3. To select
DMA channel 1, reset jumpers JP4 and
JP5 to 2-3.
If you have SMC 669, leave both jumpers open.

2.8.3 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 2-3.
2.8.4 Setting the Keyboard Clock
By default, the keyboard clock is set to 8
MHz. However, you may increase it to
12 MHz by simply resetting jumper
CN15 to 2-3.

2.8.5 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 JP3 open and
changing the BIOS setting. For detailed
information on BIOS, see Chapter 3.

2.8.6 Clearing the CMOS
You need to clear the CMOS if you
forget your system password. To do
this, shut off the system power and short
JP1 for a few seconds. Reset the jumper
to normal setting by opening pins 1-2.
Enter Setup to specify a new password
