in this generic service guide. In such cases, please contact your regional offices or the res ponsible
personnel/channel to provide you with further technical details.

2. Please note WHEN ORDERING FRU P ARTS, that you should check the most up-to-date information
available on you r regional web or channel. If , for whatever reason, a part number cha nge is made, it will
not be noted in the printed Serv ic e 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 li st provided by your regio nal Acer office to order FRU parts for repair and
service of customer machines.

System Utilities

BIOS Setup Utility

The BIOS Utility is a hardware configuration program built into your system’s Basic Input/Output System
(BIOS).

Since most systems are already properly configured and optimized, there is no need to run this utility.
However, if you encounter configuration problems and get the “Run Setup” message, you will need to run this
utility.

Before you run Setup, ma ke sure that you have saved all open fil es. The system reboots immediately after
you exit Setup.

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

cannot retain configuration value s in CMOS. Ask a quali fied technicia n for assistance.

Power-On Self-T est (POST)

Each time you turn on the system, the power-on self test (POST) is initiated. Several items are tested during
POST, but is for the most part transparent to the user.

The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the
system component s, and cont rols t he operation of the power-on passwor d option. If POST discovers er rors in
system operations at power-on, it displays error messages on sc reen, generates a check point code at port
80h or even halts the system if the error is fatal.

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



Microprocessor with built-in numeric coprocessor and cache memory subsystem



Direct memory access (DMA) controller (8237 modul e)

POST Error Messages List

If you cannot run the diagnostics program tests but did receive a POST error mes sage, use “POST Error
Messages Li st” to diagnose system problems. If you did not receive any error message, look for a description
of your error sympt om s in “Error Symptoms List ” on page 53

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

system check to ensu re that no other activity has been affected by the change. This system check can
be done through the diagn ostics program.

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

Also check the power supply voltages if you have a “sys tem no-power” conditio n.

If you are unable to correct the problem by using the “BIOS Messages List” tabl e and “Error Symptoms List”
table, go to “Undetermined Problems” on page 57.

NOTE: To diagnose a problem, first f ind the BIOS error messages in le ft 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 li sted in right column is the most l ikely cause.

Floppy Disk / Hard Disk Support

The board com es with an enhanced PC I IDE controller that supports PIO mode 4 and Ultra DMA (Direct

support a maximum of four IDE hard disk s, or any other IDE devi ces. See “J umpers and Conne cto rs” on page
59 for the location of the IDE interfaces.

Connect the cables according to the IDE hard disk configuration listed in the table below. Follow the
instructions in the housing installation manual on how to install a hard disk in the system.

These connectors enable the system to accomm odate external audio dev ices.

USB Support

USB is a new serial bus design that is capable of cascading low and medium-speed peripherals (less than 12
Mbps) such as a keyboard, mouse, joystick, sc anner, printer and modem/ISDN. With USB, complex cable
connections at the back panel of your PC can be eliminated.

The board comes with t wo USB ports (CN2) . See “Jumpers and Con nect ors” on pag e 59 for the locati on of the
ports.

Modem Ring-in Function

The Modem Ring- in function enables the system to resume f rom suspend mode by monitoring the fax/modem
(or any device of si m il ar type) activit ies. Any signal or activity detected from the Modem ring-in connector
automatical ly returns the system to normal operation. Refer to “Jumpers and Connectors” on page 59 for the
location of the Modem ring-in connector (CN17) on the system board.

Wake-on LAN

The Wake-on LAN (WOL) feature is a special feature that allows the system to be activated by a network
connection vi a the onboard WOL connector (CN1). Asi de from WOL, common network functions such as
remote access, file sharing, etc. are also supported.
