AOpen DE45-PRO Bios R1.03

This article provides information regarding the AOpen DE45-PRO motherboard BIOS update, specifically version R1.03. This update includes several improvements and changes designed to enhance the overall system functionality and stability. This article details the changes included in this specific BIOS update and provides instructions on how to apply the update using both Windows and DOS-based tools.

Understanding the Importance of BIOS Updates

The Basic Input/Output System (BIOS) is a crucial piece of firmware embedded on a computer’s motherboard. It initializes the hardware components during the boot process and provides essential low-level functions for the operating system to interact with the hardware. BIOS updates are released by motherboard manufacturers to address bugs, improve compatibility with newer hardware, enhance system performance, and introduce new features. Keeping your BIOS up-to-date is important to ensure the longevity and optimal performance of your system.

AOpen DE45-PRO Bios R1.03: What’s New

The AOpen DE45-PRO Bios R1.03 includes the following key improvements:

  1. Improved AC Power Lost Function Coverage: This update enhances the system’s ability to manage power loss events. Specifically, it improves the coverage and reliability of the AC power loss function. This means the system is better equipped to handle unexpected power outages and resume operation more smoothly when power is restored. The specific technical details of this improvement are not provided, but it likely involves refined power management algorithms and improved detection of power loss events. This improvement is crucial for preventing data loss and system instability in environments where power outages are common.

  2. Removal of "Disable" Option in "Internal Graphics Mode Select": The "Internal Graphics Mode Select" option in the BIOS setup allows users to choose which graphics adapter to use: the integrated graphics processing unit (iGPU) built into the CPU or a dedicated graphics card. In previous BIOS versions, the option may have included a "Disable" setting, potentially leading to confusion or unintended consequences. This update removes the "Disable" option, streamlining the configuration process and preventing users from inadvertently disabling the iGPU. This change likely simplifies the BIOS settings and reduces the possibility of misconfiguration. The updated BIOS now offers more intuitive choices for graphics mode selection.

  3. Support for Wake-on-LAN (WOL) After AC Loss and Recovery: Wake-on-LAN (WOL) is a networking feature that allows a computer to be powered on remotely over a network connection. This update adds support for WOL functionality even after the system has experienced an AC power loss and subsequent recovery. Previously, WOL might not have functioned reliably after a power outage. This enhancement makes it possible to remotely power on the AOpen DE45-PRO system even after a power interruption, improving its suitability for remote management and always-on applications. This improvement requires the appropriate WOL settings to be configured in both the BIOS and the operating system.

Updating the AOpen DE45-PRO Bios R1.03

The AOpen DE45-PRO Bios R1.03 update can be performed using two different methods: a Windows-based utility (AFUWIN.EXE) and a DOS-based utility (AFUDOS.EXE).

Method 1: Using AFUWIN.EXE (Windows Flash Tool)

AFUWIN.EXE is a Windows-based flashing tool that provides a user-friendly interface for updating the BIOS. This method is generally preferred for its ease of use.

  • Preparation:

    • Download the AOpen DE45-PRO Bios R1.03 update package.
    • Extract the contents of the package to a convenient location on your hard drive.
    • Locate the AFUWIN.EXE file within the extracted folder.

  • Updating the BIOS:

    1. Close all running applications in Windows.
    2. Double-click the AFUWIN.EXE file to launch the utility.
    3. The AFUWIN application will typically automatically detect the current BIOS version and the new BIOS image file. If not, you may need to manually select the .ROM file containing the BIOS update.
    4. Follow the on-screen instructions provided by the AFUWIN utility.
    5. The utility will typically prompt you to confirm the update process.
    6. Once the update process begins, do not interrupt it. Interrupting the BIOS update can render your motherboard unusable.
    7. The utility will display a progress bar and provide status updates during the update process.
    8. Once the update is complete, the utility will prompt you to restart your computer.
    9. Restart your computer to complete the BIOS update process.
  • All Update This will update all the BIOS.

Method 2: Using AFUDOS.EXE (DOS Utility)

AFUDOS.EXE is a DOS-based utility that can be used to update the BIOS from a DOS environment. This method is generally more complex than using the Windows-based utility but may be necessary in certain situations, such as when the Windows operating system is not functioning correctly.

  • Preparation:

    • Download the AOpen DE45-PRO Bios R1.03 update package.
    • Extract the contents of the package to a convenient location.
    • You will need to create a bootable DOS USB drive or CD. There are various tools available for creating bootable DOS media.
    • Copy the AFUDOS.EXE file and the BIOS .ROM file to the bootable DOS media.

  • Updating the BIOS:

    1. Boot your computer from the bootable DOS media.

    2. At the DOS prompt, navigate to the directory containing the AFUDOS.EXE file and the BIOS .ROM file.

    3. Run the AFUDOS utility with the following command-line parameters:

      AFUDOS filename.ROM /P /B /N /C
      • filename.ROM: Replace this with the actual name of the BIOS .ROM file.
      • /P: Program the main BIOS region.
      • /B: Program the Boot Block region.
      • /N: Program the NVRAM region.
      • /C: Clear CMOS after programming.

    4. Press Enter to execute the command.

    5. The AFUDOS utility will begin the BIOS update process.

    6. Do not interrupt the update process.

    7. Once the update is complete, the utility will display a message indicating that the update was successful.

    8. Restart your computer to complete the BIOS update process.

Important Considerations

  • Backup Your Existing BIOS: Before updating the BIOS, it is always recommended to create a backup of your existing BIOS. This can be done using the AFUWIN or AFUDOS utility. In case the BIOS update fails or causes problems, you can restore the backed-up BIOS to revert to the previous state.
  • Uninterruptible Power Supply (UPS): It is highly recommended to perform the BIOS update while connected to an uninterruptible power supply (UPS). This will prevent the update process from being interrupted by a power outage.
  • Compatibility: Ensure that the AOpen DE45-PRO Bios R1.03 update is specifically designed for your AOpen DE45-PRO motherboard. Using an incorrect BIOS version can damage your motherboard.
  • Risk: Updating the BIOS is a potentially risky procedure. If performed incorrectly, it can render your motherboard unusable. Proceed with caution and follow the instructions carefully. If you are not comfortable updating the BIOS yourself, it is best to seek assistance from a qualified computer technician.
