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 drives and peripherals

• Specifying the boot device sequence

• Configuring the power management modes

• Setting up system passwords or making other changes to the security setup

• When trying to resolve IRQ conflicts

• When a configuration error is detected by the system and you are prompted ("Run Setup" message) to make changes to the BIOS settings.

The Setup Utility loads the configuration values in a battery-backed nonvolatile memory called CMOS RAM. 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.

NOTE For ease of reading, CMOS Setup Utility will be simply referred to as “Setup” or “Setup Utility” in this

Service Guide.

Accessing the Setup Utility

1. Turn on the computer. If the computer is already turned on, save your data and close all open applications, then restart the

computer.

2. During POST, press Delete. If you fail to press Delete before POST is completed, you will need to restart the computer.

Use the Up/Down/Left/Right arrow keys to move between the menu options, then press Enter to execute that option.

Some options lead to pop-up dialog boxes that prompt you to verify that you wish to execute that option. Other options lead to dialog boxes that prompt you for information.

Some options (marked with a ) lead to submenus that enable you to change the values for the option. Use the Up/Down/Left/Right arrow keys to scroll through the items in the submenu

Troubleshooting

This chapter lists the POST error indicators and BIOS beep codes, as well general troubleshooting instructions.

Hardware Diagnostic Procedure

1. Obtain as much detail as possible about the symptoms of the system failure.

2. Verify the symptoms by attempting to recreate the failure by running the diagnostic tests or repeating th e

same operation.

3. Refer to “Power System Check” procedure on the next section and the “Beep Codes” section on page 76 to determine which corrective action to take.

System Check Procedures

IMPORTANT The diagnostic tests described in this chapter are only intended to test Acer products.

Non-Acer products, prototype cards, or modified options can give false errors and invalid system responses.

Power System Check

If the system can be powered on, skip this section. Proceed to the “System Internal Inspection” procedure on the next page.

If the system will not power on, do the following:

• Check if the power cable is properly connected to the AC power jack and a functional AC power source.

• Check if the voltage selector switch is set to the correct voltage setting.

System External Inspection

1. Inspect the power and LED indicators on the front panel. Go to “Front View” section on page 3 for the location and description of the LED behaviour.

2. Make sure that the ventilation slots on the rear panel are not blocked.

3. Make sure that there is no point of contact in the system that can cause a power short.

If the cause of the failure is still can not be determined, perform the “System Internal Inspection” procedure described on the next page.

Packard Bell oneTwo M3350 / oneTwo M3351 / oneTwo L5350 / oneTwo L5351 Service Guide 61

System Internal Inspection

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

2. Unplug the power cord from the computer.

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

4. Place the computer on a flat, steady surface.

5. Remove the side panel as described in page 20.

6. Verify that the processor, memory module(s), and expansion board(s) are properly seated.

7. Verify that all power and data cables are firmly and properly attached to the installed drives.

8. Verify that all cable connections inside the system are firmly and properly attached to their appropriate

mainboard connectors.

9. Verify that all components are Acer-qualified and supported.

10. Reinstall the side panel.

11. Power on the system.

If the cause of the failure is still can not be determined, review the POST messages and BIOS checkpoints during the system startup.

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 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.

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.

Checkpoint Description

Before D1 Early chipset initialization is done. Early super I/O initialization is done including RTC and

keyboard controller. NMI is disabled.

D1 Perform keyboard controller BAT test. Check if waking up from power management

suspend state. Save power-on CPUID value in scratch CMOS. D0 Go to flat mode with 4GB limit and GA20 enabled. Verify the bootblock checksum. D2 Disable CACHE before memory detection. Execute full memory sizing module. Verify that

flat mode is enabled. D3 If memory sizing module not executed, start memory refresh and do memory sizing in

bootblock code. Do additional chipset initialization. Re-enable CACHE. Verify that flat

mode is enabled. D4 Test base 512 KB memory. Adjust policies and cache first 8 MB. Set stack.

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 unit during the BIOS recovery process.

• The BIOS crisis recovery disk should be prepared in a computer running the Windows XP or Wind ows Vista OS.

Creating the BIOS Crisis Recovery Disk

1. Prepare a removable USB storage device with a capacity size greater than 10 MB. Note that all data on the USB storage device will be cleared during the creation of the crisis disk.

2. Set up a computer running the Windows XP or Windows Vista operating system and plug in the USB storage device into an available USB port.

3. Copy the target BIOS ROM file to the USB storage device and rename it as “amiboot.rom”.

4. Unplug the USB storage device.

5. Eject the removable USB storage device from the computer.

Performing a BIOS Recovery

1. Shut down the BIOS failed-computer.

2. Connect the USB storage device containing the “amiboot.rom” file to the failed computer.

3. Press the power button to turn on the computer.

The system will now execute the BIOS recovery process. When the process is complete, four short beeps will be emitted and the computer will automatically reboot.

4. Disconnect the USB storage device from the computer.

5. Press Delete to run the CMOS Setup Utility.

6. Press F9 to load the system default settings.

7. Select Ok, then press Enter.

8. Press F9 to save the default settings and close the Setup utility.

9. Select Ok, then press Enter.

Use the JBIOS1 jumper to clear the CMOS data.

• 1-2 position: Normal operation (default)

• 2-3 position: Clear CMOS data

To clear the CMOS data:

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

2. Unplug the power cord from the computer.

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

4. Place the computer on a flat, steady surface with the rear cover facing upward.

5. Reinstall the rear cover by following the procedure described on page 28.

6. Remove the wall mount plate by following the procedure described on page 35.

7. Remove the graphics card by following the procedure described on page 37

8. Remove the hard drive by following the procedure described on page 40.

9. If necessary, remove any other assemblies or cables that prevent access to the CMOS clear jumper.

10. Locate the JBIOS1 jumper on the mainboard.

11. Remove the jumper block and set it over the 2-3 pins for 20 to 30 seconds.

12. Return the jumper block to its default 1-2 position.

13. Reinstall the hard drive, graphics card, and the wall mount plate.

14. Reinstall any any other assemblies or cables that have previously been removed.
