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.

Chapter 4
![](asset-46.png)
62 Packard Bell oneTwo M3350 / oneTwo M3351 / oneTwo L5350 / oneTwo L5351 Service Guide
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.
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.
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.
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.

Boot Block Recovery Code Checkpoints
The boot block recovery code gets control when the BIOS determines that a BIOS recovery is required
because the user has forced the update or the BIOS checksum is corrupt. Refer to “BIOS Recovery” section
on page 77 for more information. The following table describes the type of checkpoints that may occur during
the boot block recovery portion of the BIOS.
D5 Bootblock code is copied from ROM to lower system memory and control is given to it.
BIOS now executes out of RAM.
D6 Both key sequence and OEM specific method is checked to determine if BIOS recovery is
forced. Main BIOS checksum is tested. If BIOS recovery is necessary, control flows to
checkpoint E0. See the “Boot Block Recovery Code Checkpoints” section for more
information.
D7 Restore CPUID value back into register. The Bootblock Runtime interface module is
moved to system memory and control is given to it. Determine whether to execute serial
flash.
D8 The Runtime module is uncompressed into memory. CPUID information is stored in
memory.
D9 Store the Uncompressed pointer for future use in PMM. Copying Main BIOS into memory.
Leaves all RAM below 1 MB Read-Write including E000 and F000 shadow areas but
closing SMRAM.

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 Windows
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.
