Service Guide Coverage

This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION
decided for our "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.

FRU Information

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 AUTHORIZED SERVICE PROVIDERS, your 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

CMOS Setup Utility

CMOS Setup Utility is a hardware configuration program built into the system ROM. Since most systems are
already properly configured and optimized, there is normally no need to run this utility.

You will need to run this utility under the following conditions:

• When changing the system configuration including:

• Setting the system time and date

• Configuring the system dr

• Specifying the boot device sequence

• Configuring the power management modes

• Setting up system passwords or making other changes to

• When trying to resolve IRQ conflicts

• When a configuration error is detected by th

This memory area is not part of the system RAM, which allows configuration data to be retained when power is
turned off. The values take effect when the system is booted. POST uses these values to configure the
hardware. If the values and the actual hardware do not agree, POST generates an error message. You must
run this utility to change the hardware settings from the default or current configuration.

IMPORTANT If you repeatedly receive “Run Setup” messages, the RTC battery located on the mainboard

(BT1) may be defective. In this case, the system cannot retain configuration values in CMOS.
Replace the RTC battery with a new one.

l can not be determined, review the POST messages and BIOS

Checkpoints

A checkpoint is either a byte or word value output to I/O port 80h. The BIOS outputs checkpoints during
bootblock and Power-On Self Test (POST) to indicate the task the system is currently executing. Checkpoints
are very useful in aiding software developers or technicians in debugging problems that occur during the
pre-boot process.

Viewing BIOS Checkpoints

Viewing all checkpoints generated by the BIOS requires a checkpoint card, also referred to as a POST card or
POST diagnostic card. These are ISA or PCI add-in cards that show the value of I/O port 80h on a LED
display. Checkpoints may appear on the bottom right corner of the screen during POST. This display method
is limited, since it only displays checkpoints that occur after the video card has been activated.

NOTE

Boot Block Initialization Code Checkpoints

The boot block initialization code sets up the chipset, memory, and other components before system memory
is available. The following table describes the type of checkpoints that may occur during the boot block
initialization portion of the BIOS.

Please note that checkpoints may differ between different platforms based on system
configuration. Checkpoints may change due to vendor requirements, system chipset or option
ROMs from add-in PCI devices.

mode and will either:

• Displays a POST error message, or

• Emits a series of beep codes

BIOS Recovery

When you boot up the computer and you hear one long beep, followed by a shorter one, the system BIOS is
damaged. This maybe cause by an interruption during a BIOS flash procedure (e.g. a power outage) or a
corrupted BIOS code, which will cause the system to go into an unbootable state.You need to access and
execute the boot block program to reboot the computer and recover the regular BIOS code.

Note the following when restoring the BIOS settings:

• Make sure the computer is connected to a UPS u

Clearing CMOS

You may need to clear the Setup configuration values (CMOS) if the configuration has been corrupted, or if
incorrect settings made in the Setup Utility caused error messages to be unreadable. This procedure will clear
the BIOS supervisor password as well.

Use the JBIOS1 jumper to clear the CMOS data.

• 2-3 position: Clear CMOS data

To clear the CMOS data:

1. Turn off the power to the computer and all peripherals.

3. Unplug the network cable and all connected peripheral devices from the computer.

4. Place the computer on
