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 (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. Gently insert the CPU. Make sure
that pin 1 of the CPU aligns with
hole 1 of the socket. The notched
corner on the CPU indicates the
location of pin 1.
3. Pull down the socket lever to lock
the CPU into the socket.

2.6 Configuring the System Memory
The system board has four 72-pin SIMM sockets that allow you to expand the
system memory to 512 MB. The SIMM sockets accept single-density and
double-density SIMMs with 60 or 70-ns DRAM speed. See the figure in
section 1.1 for the location of the SIMM sockets.

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

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 Selecting the Flash ROM Type
The AP53 board supports both the 5V
and 12V Flash ROM types. Normally,
the board comes with a 5V Flash ROM
and with the jumpers JP1301 and
JP1302 set to 1-2. Reset JP1301 to 2-3
if you want to install a 12V Flash ROM.
5V
(default)
12V
JP1301 JP1302
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 JP8 to 2-3.

2.7.3 Selecting the ECP DMA Channel
The available ECP DMA channel
selections are DRQ3/DACK3 and
DRQ1/DACK1. The default is
DRQ3/DACK3. To select
DRQ1/DACK1, reset jumpers JP6 and
JP7 to 2-3.
The onboard I/O controller may either be SMC
665 or SMC 669. If you have SMC 669, JP6
and JP7 must be set to open.
2.7.4 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
pins 2-3 of JP5 for a few seconds. Reset
the jumper to normal setting by shorting
pins 1-2. Enter Setup to specify a new
password.

2.7.5 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 opening jumper JP4 and changing the
BIOS setup. For detailed information on
BIOS, see Chapter 3.
2.7.6 Setting the Keyboard Clock
The jumper JP1401 enables you to set
the keyboard clock. The clock
selections are ISA clock and 12 MHz.
Set JP1401 to 1-2 to select the ISA
clock. Reset it to 3-4 to set the keyboard
clock to 12 MHz.
