Preface

Before using this information and the product it supports, please read the following general information.

1. This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION
decided for Acer's "global" product offering. To better fit local market requirements and enhance product
competitiveness, your regional office MAY have decided to extend the functionality of a machine (e.g.
add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered
in this generic service guide. In such cases, please contact your regional offices or the responsible
personnel/channel to provide you with further technical details.

2. Please note WHEN ORDERING FRU PARTS, that you should check the most up-to-date information
available on your regional web or channel. If, for whatever reason, a part number change is made, it will
not be noted in the printed Service Guide. For ACER-AUTHORIZED SERVICE PROVIDERS, your Acer
office may have a DIFFERENT part number code to those given in the FRU list of this printed Service
Guide. You MUST use the list provided by your regional Acer office to order FRU parts for repair and
service of customer machines.

System Utilities

Most systems are already configured by the manufacturer or the dealer. There is no need to run
Setup when starting the computer unless you get a Run Setup message.

The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM.
This memory area is not part of the system RAM.

NOTE: If you repeatedly receive Run Setup messages, the battery may be bad/flat. In this case, the system

cannot retain configuration values in CMOS.

Before you run Setup, make sure that you have saved all open files. The system reboots immediately after you
exit Setup.

Chapter 2 19

Entering Setup

Power on the computer and the system will start POST (Power On Self Test)process. When the message of
“Press DEL to enter SETUP” appears on the screen, press the key of [Delete] to enter the setup menu.

NOTE: If the message disappears before you respond and you still wish to enter Setup, restart the system by

turning it OFF and On. You may also restart the system by simultaneously pressing [Ctrl+Alt+Delete].

The Setup Utility main menu then appears:

The parameters on the screens show default values. These values may not be the same as those in your
system.

The grayed items on the screens have fixed settings and are not user-configured.

NOTE: Due to the application of a new version of BIOS Setup program, you may find the BIOS menu is largely

different from the former models. However, you will soon find out that this version is much more
compact than the former ones.

Base Memory Refers to the option of memory that is available

to standard DOS programs. DOS systems have
an address space od 1MB, but the top 384KB
(called high memory) is reserved for system use.
This leaves 640 KB of conventional memory.
Everything above 1MB is either extended or
extended memory.

Extended Memory Memory above and beyond the standard 1MB of

base memory that DOS supports. Extended
memory is only available in PCs with an Intel
80286 or later microprocessor. Extended
memory is not configured in any special manner
and is therefore unavailable to most DOS
programs. However, MS Windows and OS/2 can
use extended memory.

Spread Spectrum When the motherboard’s clock generator pulses,

the extreme values (spikes) of the pulses creates
EMI (Electromagnetic Interference). The spread
Spectrum function reduces the EMI generated by
modulating the pulses so that the spikes of the
pulses are reduced to flatter curves. If you do not
have any EMI problem, leave the setting at
Disabled for optimal system stability and
performance. But if you are plagued by EMI,
setting to Enabled for EMI reduction. Remember
to disable Spread Spectrum if you are
overlocking because even a slight jitter can
introduce a temporary boost in clockspeed which
may just cause your overlock ed processor to
lock up.

This option opens a dialog box that lets you install defaults for all appropriate items in the Setup Utility.

Press <Y> and then <Enter> to install the defaults. Press <N> and then <Enter> to not install the defaults. The
defaults place demands on the system that may be greater than the performance level of the components,
such as the CPU and the memory. You can cause fatal errors or instability if you install the optimized defaults
when your hardware does not support them. If you only want to install setup defaults for a specific option,
select and display that option.

When this function is selected, the following message appears at the center of the screen to assist you in
creating a password.

Type the password, up to eight characters, and press <Enter>. The password typed now will clear any
previously entered password from CMOS memory. You will be asked to confirm the password. Type the
password again and press <Enter>. You may also press <Esc> to abort the selection.

To disable password, just press <Enter> when you are prompted to enter password. A message will confirm
the password being disabled. Once the password is disabled, the system will boot and you can enter BIOS
Setup freely.

Supervisor Password has higher priority than User Password. You can use Supervisor Password when
booting the system or entering BIOS Setup to modify all settings. Also you can use User Password when
booting the system or entering BIOS Setup but can not modify any setting if Supervisor Password is enabled.

Power-On Self-Test (POST)

Before the computer can be used, all the components must be tested and initialized, and the operating system
must be bootstrapped into memory. This process is know as the power-on Self test(POST), generally under
the control of the BIOS.

The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the
system components, and controls the operation of the power-on password option. During POST, system
reports test or initialization failure through Beep codes, display error messages on screen(if available), or LED.
The system halts when fatal error occurs.

The main components on the main board that must be diagnosed and/or initialized by POST to ensure system
functionality are as follows:

T Microprocessor with built-in numeric co-processor and cache memory subsystem

T Direct Memory Access (DMA) controller

T Interrupt system

T Three programmable timers

T ROM subsystem

T RAM subsystem

T RTC RAM subsystem and real time clock/calendar with battery backup

T Onboard serial interface controller

T Onboard parallel interface controller

T Embedded hard disk interface and one diskette drive interface

T Keyboard and auxiliary device controllers

T I/O ports

T PS/2-compatible mouse port

T PS/2-compatible keyboard port

T Serial ports

POST Check Points

When POST executes a task, it uses a series of preset numbers called check point to be latched at port 80h,
indicating the stages it is currently running. This latch can be read and shown on a debug board.

The following table describes the Acer common tasks carried out by POST. A unique check point number
represents each task.

POST Error Messages List

If you cannot run the diagnostics program tests but did receive a POST error message, use “POST Error
Messages List” to diagnose system problems. If you did not receive any error message, look for a description
of your error symptoms in “Error Sympton List”.

NOTE: When you have deemed it necessary to replace an FRU, and have done so, you must run a total

system check to ensure that no other activity has been affected by the change. This system check can
be done through the diagnostics program.

NOTE: Check all power supply voltages, switch, and jumper settings before you replace the main board. Also

check the power supply voltages if you have a “system no-power” condition.

NOTE: To diagnose a problem, first find the BIOS error messages in the left column. If directed to a check

procedure, replace the FRU indicated in the check procedure. If no check procedure is indicated, the
first Action/FRU listed in right column is the most likely cause.
