AOpen DE45-HG Bios R1.02

The AOpen DE45-HG Bios R1.02 update addresses specific display resolution compatibility issues and provides tools for updating the BIOS (Basic Input/Output System) on AOpen DE45-HG motherboards. This article will detail the improvements included in this version and provide guidance on how to apply the update using both Windows-based and DOS-based utilities. Understanding the importance of BIOS updates and the correct procedures for applying them is crucial for maintaining system stability and compatibility.

What’s New in AOpen DE45-HG Bios R1.02:

This particular BIOS update focuses on expanding the display resolution options available for the AOpen DE45-HG. The primary enhancement is the addition of support for the following resolutions:

  • 1360×768
  • 1440×900

These resolutions are commonly found on various LCD monitors, and this update ensures that the AOpen DE45-HG system can properly display content at these resolutions without potential display issues like stretching, distortion, or incorrect scaling. For users employing monitors with these native resolutions, this update is highly recommended.

Why Update Your BIOS?

The BIOS is a fundamental piece of software embedded within the motherboard. It’s responsible for initializing hardware components during the boot process, providing essential system information, and managing low-level interactions between the operating system and hardware. Updating the BIOS can address a range of issues, including:

  • Improved Hardware Compatibility: Newer BIOS versions often include support for newly released processors, memory modules, graphics cards, and other peripherals.
  • Bug Fixes: BIOS updates can resolve bugs that may cause system instability, crashes, or performance issues.
  • Enhanced Security: Some BIOS updates address security vulnerabilities that could be exploited by malicious software.
  • Improved Performance: While less common, BIOS updates can sometimes optimize system performance by fine-tuning hardware settings.

Updating the AOpen DE45-HG Bios R1.02

The AOpen DE45-HG Bios R1.02 update provides two methods for updating the BIOS: a Windows-based utility (AFUWIN.EXE) and a DOS-based utility (AFUDOS.EXE). Before proceeding with either method, it is crucially important to back up your existing BIOS in case of unforeseen issues during the update process. A corrupted BIOS can render your system unusable. It is also recommended to have an Uninterruptible Power Supply (UPS) to prevent power loss during the flashing procedure.

Method 1: Updating via Windows (AFUWIN.EXE)

AFUWIN.EXE is a user-friendly Windows-based flashing tool that simplifies the BIOS update process.

  1. Download the Update: Download the AOpen DE45-HG Bios R1.02 update package from a reputable source (see download links below).
  2. Extract the Files: Extract the contents of the downloaded ZIP file to a folder on your hard drive.
  3. Locate AFUWIN.EXE: Find the AFUWIN.EXE file within the extracted folder.
  4. Run AFUWIN.EXE: Double-click AFUWIN.EXE to launch the application. You may need to run the application as an administrator.
  5. Follow On-Screen Instructions: The AFUWIN utility will guide you through the update process. Typically, it will automatically detect the BIOS file (usually a .ROM file) included in the extracted folder.
  6. Initiate the Update: Click the "Flash" or "Update" button to begin the BIOS update process.
  7. Wait for Completion: The update process may take a few minutes. Do not interrupt the process by turning off the computer or restarting it.
  8. Restart Your Computer: Once the update is complete, the utility will prompt you to restart your computer. Allow the system to restart.

Method 2: Updating via DOS (AFUDOS.EXE)

AFUDOS.EXE is a DOS-based flashing tool that requires booting into a DOS environment. This method is typically used when the Windows-based utility fails or when the system is unable to boot into Windows.

  1. Download the Update: Download the AOpen DE45-HG Bios R1.02 update package from a reputable source (see download links below).
  2. Extract the Files: Extract the contents of the downloaded ZIP file to a folder on your hard drive.
  3. Create a Bootable DOS USB Drive: You will need a bootable DOS USB drive. You can create one using various tools available online (e.g., Rufus).
  4. Copy Files to the USB Drive: Copy the AFUDOS.EXE file and the BIOS ROM file (e.g., filename.ROM) to the bootable DOS USB drive.
  5. Boot from the USB Drive: Restart your computer and enter the BIOS setup (usually by pressing Del, F2, or F12 during startup). Configure the boot order to boot from the USB drive.
  6. Run AFUDOS.EXE: Once booted into DOS, navigate to the USB drive by typing the drive letter (e.g., E: ) and pressing Enter.
  7. Execute the Update Command: Type the following command and press Enter: AFUDOS filename.ROM /P /B /N /C
    • filename.ROM is the name of the BIOS ROM file.
    • /P programs the main BIOS.
    • /B programs the boot block.
    • /N programs the NVRAM.
    • /C clears the CMOS checksum.
  8. Wait for Completion: The update process may take a few minutes. Do not interrupt the process by turning off the computer or restarting it.
  9. Restart Your Computer: Once the update is complete, the utility will prompt you to restart your computer. Remove the USB drive and allow the system to restart.

Important Considerations:

  • Verify Compatibility: Ensure that the AOpen DE45-HG Bios R1.02 is specifically designed for your AOpen DE45-HG motherboard model. Using an incorrect BIOS version can severely damage your system.
  • Power Stability: Maintain a stable power supply throughout the update process. A power outage can interrupt the flashing process and potentially corrupt the BIOS. Use a UPS if possible.
  • Backup Your BIOS: Before updating, back up your existing BIOS. This allows you to revert to the previous version if any issues arise during the update process. The AFUWIN utility usually provides an option to back up the BIOS.
  • Read the Documentation: Refer to the documentation provided with the BIOS update for specific instructions and precautions.
  • If unsure, seek expert help: If you are uncomfortable with any aspect of the BIOS update process, seek assistance from a qualified computer technician.
