Static Electricity Precautions
Components on this mainboard can be damaged by static
electricity. Take the following precautions when unpacking the
mainboard and installing it in a system.
1. Keep the mainboard and other components in their original
static-proof packaging until you are ready to install them.
2. During installation, wear a grounded wrist strap if possible. If
you don’t have a wrist strap, discharge static electricity by
touching the bare metal of the system chassis.
3. Handle the mainboard carefully by the edges. Avoid touching
the components unless it is absolutely necessary. During
installation put the mainboard on top of the static-protection
packaging it came in with the component side facing up.
Pre-Installation Inspection
1. Inspect the mainboard for damage to the components and
connectors on the board.
2. If you suspect that the mainboard has been damaged, do not
connect power to the system. Contact your mainboard vendor
and report the damage.

Chapter 2
Mainboard Installation
To install this mainboard in a system, follow the procedures in this
chapter:
Identify the mainboard components
Install a CPU
Install one or more system memory modules
Verify that any jumpers or switches are set correctly
Install the mainboard in a system chassis (case)
Connect any extension brackets or cables to the mainboard
connector headers
Install any other devices and make the appropriate connections
to the mainboard connector headers.
Note:
1. efore installing this mainboard, make sure jumper J3 is set to
Normal, the default setting is set to Clear CMOS. See this
chapter for information on locating J3 and the setting options.
2. Never connect power to the system during installation. Doing
so may damage the mainboard.

I/O Ports
The illustration below shows a side view of the built-in I/O ports
on the mainboard.
Install A CPU
This mainboard has a Socket-7 which may be installed with any of
the socket-7 processors including the Intel P55C (MMX) series,
the Cyrix/I M 6x86L/6x86MX/MII series, the AMD K6/K6-2/K-
III series, the IDT C6/Winchip 2/2A series. The mainboard
supports system bus speeds of 60, 66, 75, 83, 90, 95, 100 MHz.
Do not try to install a Socket-370 processor in the Socket-7. A
Socket-370 processor such as the PPGA Celeron or FCPGA
Pentium III does not fit in the Socket-7.
The board supports CPU plug and play, so the system can
automatically run the installed processor with the correct clock
speed and the correct system bus frequency. To automatically
configure the processor, use the IOS setup program to select the
clock speed and system bus frequency. See chapter three for more
information.
To ensure reli bility, m ke sure th t your socket-7 processor is
fitted with he tsink/cooling f n ssembly.

M581 Mainboard User’s Manual
The socket-7 processor installs into the ZIF (Zero Insertion Force)
socket-7 on the mainboard.
1. Locate the Socket-7 and J1. Pull the locking lever out slightly
from the socket and raise it to the upright position.
2. On the processor, identify the Pin-1 corner by its beveled edge.
3. On the Socket-7, identify the Pin-1 corner. The Pin-1 corner is
at the end of the locking lever when it is locked.
4. Match the Pin-1 corners and insert the processor into the
socket. No force is required and the processor should drop into
place freely.
5. Swing the locking lever down and hook it under the catch on
the side of the socket. This secures the CPU in the socket.
6. All processors should be installed with a combination heatsink/
cooling fan, connect the cable from the fan to the CPU fan
power connector J1.
Install emory
The mainboard has two DIMM sockets for system memory
modules. You must install at least one memory module in order to
use the mainboard.
10
Socket-7
Pin-1 Corner
J1

2: Mainboard Installation
For this mainboard, you must use 168-pin, 3.3V unbuffered
SDRAM memory modules. If the installed CPU uses a 100 MHz
system bus, you must use PC100 memory. If the installed CPU
uses a 66 MHz system bus, you must use PC66 memory. You can
install any size memory module from 16 M to 512M , so the
maximum memory size is 2 x 512M = 1G .
The edge connectors on the memory modules have cut outs, which
coincide with spacers in the DIMM sockets so that memory
modules can only be installed in the correct orientation.
To install a module, push the retaining latches at either end of the
socket outwards. Position the memory module correctly and insert
it into the DIMM socket. Press the module down into the socket so
that the retaining latches rotate up and secure the module in place
by fitting into notches on the edge of the module.
Setting Jumper Switches
Jumpers are sets of pins which can be connected together with
jumper caps. The jumper caps change the way the mainboard
operates by changing the electronic circuits on the mainboard. If a
jumper cap connects two pins, we say the pins are SHORT. If a
jumper cap is removed from two pins, the pins are OPEN.

Jumper J3: Clear CMOS Memory
Use this jumper to clear the contents of the CMOS memory. You
may need to clear the CMOS memory if the settings in the Setup
Utility are incorrect and prevent your mainboard from operating.
To clear the CMOS memory, disconnect all the power cables from
the mainboard and then move the jumper cap into the CLEAR
setting for a few seconds.
