If your motherboard has already been installed in your computer you may still need to

refer to this chapter if you plan to upgrade your system's hardware.

Besuretodisconnectthepowercablefromthepowersourcebeforeperforming

any work on your motherboard, i. e. installing a CPU, memory module,

changing a jumper setting, etc. Not doing so may result in electrical shock!

2-1 Introduction to Jumpers

Jumpers are used to select between various operating modes. A jumper consists of

a row of gold colored pins that protrude from the surface of the motherboard. It is

important not to confuse jumpers with connectors or headers.

Puttingjumpercapsonanythingthatisnotajumpermayresultindamaging

your motherboard. Please refer to Section 1-3, Motherboard Layout, for the

location of jumpers on your motherboard.

As indicated in Figure 2-1 below, a cap is used to cover the pins of a jumper, resulting

in shorting those pins that it covers. If the cap is removed from the top of the pins,

the jumper is left "open." The number 1 shown both in the diagram below and in

allmultiple pinjumper andheaderdiagrams inthis manualindicates thepin designated

with the number 1. The numbering of the remaining pins follows in sequence.

2-2 Installing an Intel Processor in Slot 1

1. Insert the Pentium II/Pentium III processor into the retention mechanism. Press

evenly and gently until the snaps on the upper side of the processor have been

inserted into the holes at the top of the retention mechanism.

2. Note that when removing the processor, these snaps should be clicked into a

completely vertical position, leaving your hands free to stabilize the board. Pull

the processor evenly and gently out of the retention mechanism.

3. Also note that like PCI and ISA slots, Slot 1 has a divider that prevents backwards

insertion of the CPU.

Installing a heat sink with cooling fan is necessary for proper heat dissipation

from your CPU. Failing to install these items may result in overheating and

possible burn-out of your CPU.

2-3 SettingYour CPU's Parameters(

SeePU

Technology)

SeePU is a new user friendly technology that enables the user to setup a motherboard's

CPU parameters through an easy to use BIOS setup procedure. It is no longer

necessary to make many jumper settings.

1. After installing all your hardware into your PC system, turn on your system's

power. Enter the CMOS Setup Utility by pressing the Delete key when your

BIOS identification screen appears.

2. Move the cursor to Frequency/Voltage Control Setup menu and press Enter. Find

the CPU Setup commands at the right hand side of the BIOS screen (Figure 2-

2) Commands for operating the cursor in BIOS are found at the Bottom right of

the BIOS screen.

3. Change the CPU Type according to the speed of your Pentium II/III processor.

See Figure 2-3 for frequency specifications.

4. Set your CPU's parameters. Set the frequency ratio (also known as external clock

multiplierfactor)andCPUbusfrequencyaccordingtoyourprocessor'sspecifications.

See Figure 2-4.

You do not need to make voltage settings because SeePU automatically

sets your CPU voltage.

5. Press Esc to return to the CMOS Setup Utility, press F10 to Save and Exit Setup

and choose 'Y' to confirm. The system will automatically reboot and during startup

you will see the correct CPU type shown on the screen.

2-4 Connector and Jumper Settings

Connectors are used to link the system board with other parts of the system, including

the power supply, the keyboard, and the various controllers on the front panel of the

system case.

The power supply connector is the last connection to be made while

installing a motherboard.Before connecting the power supply, please make

sure it is not connected to the power source.

ATX Power Supply Connector (CN7)

The power cord leading from the system's power supply to

the external power source must be the very last part

connected when assembling a system.

The ATX power supply provides a single 20-pin connector

interface which incorporates standard +/-5V, +/-12V,

optional 3.3V and Soft-power signals. The Soft-power

signal, a 5V trickle supply is continuously supplied when

AC power is available. When the system is in the Soft-Off

mode, this trickle supply maintains the system in it's

minimum power state.

Software Power-Off Control

2theMax 6XBA2 can be powered down using the Windows 95/98 Software Power-Off

function. To power down your computer, click the START button on the Windows 95/98

task bar. Select "Shut Down The Computer" and the system turns off. The message "It

is now safe to turn off your computer" will not be shown when using this function.

Power-On By ModemPower-On By Modem

Power-On By Modem

While in Soft-off state, if an external modem ring-up signal occurs, the system wakes up

and can be remotely accessed. You may enable this function in BIOS's Power

Management Setup menu.
