KEEPING

THE

SYSTEM

COOL

Airflow

is

critical

for

proper

operation.

The

motherboard

contains

many

high-speed

components

and

they

will

generate

heat

during

operation.

Other

add-on

cards

and

hard

disk

drive

can

also

produce a lot

of

heat.

As a result,

the

temperature

inside

the

computer

system

may

be

very

high.

These

boards

require

cool

air

to

prevent a deadly

heat

build-up.

Be

sure

that

all

cooling

vents

in

the

front

or

sides

of

the

computer

are

open

and

that

air

circulation

is

good.

Check

the

clearance

at

the

back

of

the

computer;

the

power

supply

contains a fan

to

blow

air

out

of

the

case,

make

sure

the

fan

is

not

blocked

by

cables

or

papers.

Don't

push

your

computer

flush

against

the

wall;

leave

it

some

breathing

space.

Heat

can

destroy

compu

ter

ch

ips.

CLEANING

THE

"GOLDEN

FINGER"

Whenever

inserting

an

add-on

card

to

the

motherboard,

make

sure

that

there

is

no

dirt

on

the

"golden

finger"

of

the

add-on

card.

If

not,

the

contact

between

the

"golden

finger"

and

the

slot

may

be

poor

and

thus

causing

the

add-on

cards

to

work

improperly.

Use a pencil

eraser

to

clean

the

"golden

finger"

if

dirt

is

found.

Operation and Maintenance

Some

components

of

the

Panther-II

or

computer

components

are

static-sensitive

devices

and

can

be

damaged

by

static

discharges.

To

prevent

such

damage,

the

device

may

be

wrapped

in

a

conductive,

anti-static

bag;

certain

precautions

should

be

taken

before

removing

the

dev

ice

from

its

bags.

When

installing

or

removing

any

add-on

card,

DRAM

module

or

coprocessor,

care

should

be

taken

when

handling

these

devices.

are

installing

on

the

other

hand.

This

will

place

your

body,

the

component,

and

the

system

unit

at

the

same

ground

potential.

preventing

an

accidental

static

discharge.

Be

sure

to

handle

circuit

boards

by

the

edges

only

and

do

not

touch

the

component

pins

or

solder

joints.

Grasp

diskette

drives

or

fixed

disk

drives

by

their

frames

to

avoid

touching

the

circuit

board.

Memory

chips

or

co-processor

should

be

held

by

their

bodies

only,

not

by

their

pins.

Preventing

a

problem

is

better

than

having

to

fix

it

after

it

has

happened.

This

is

where

cleanliness

and

proper

operating

procedures

come

into

play.

OPERATION

AND

MAINTENANCE

CLEANING

THE

MOTHERBOARD

Because

the

system

is

air-cooled,

dust

can

enter

your

system

through

the

ventilation

slots.

At

least

once a year,

take

the

cover

off

your

computer

and

vacuum

the

interior

to

remove

accumulated

dust.

Use a brush

attachment

on

the

vacuum

and

carefully

go

over

all

exposed

parts.

To

prevent

dust

from

accumulating

on

the

mother-

board,

installing

all

mounting

plates

on

the

rear

of

the

case.

Regularly

examine

your

system,

and

if

necessary,

vacuum

the

interior

of

the

system

with a miniature

vacuum.

Appendix

A

AMI

System

BIOS

The

system

BIOS

of

Panther-II

provides

an

interface

for

operating

systems

and

applications

to

access

the

hardware.

It

is

fully

compatible

with

s.tandard

AT

BIOS

and

works

flawlessly

in

the

network

system.

It

also

performs

self-test

after

reset

and

includes a setup

program

to

configure

the

system.

SELF-TEST

To

ensure

that

the

computer

hardware

is

functional,

the

system

BIOS

will

carry

out a self-

test

upon

reset.

The

test

is

very

intensive

and

covers

all

parts

of

hardware.

It

takes a while

before

messages

are

shown

on

the

screen.

It

does

not

mean

that

the

system

is

not

working

when

the

screen

is

blank.

So

wait

for a while

after

turning

on

the

power

and

listen

carefully

to

the

speaker.

Some

errors

are

reported

by a number

of

beep

sounds.

After

completing

the

self-test,

the

BIOS

will

display

some

messages

on

the

screen.

In

case

of

serious

er

rors,

the

BIOS

will

suspend

the

test.

If

the

display

is

not

initialized,

the

BIOS

will

report

the

error

through a sequence

of

beep

sounds.

Otherwise,

error

message

will

be

shown

on
