The Basic Input/Output System (BIOS) is a crucial piece of firmware embedded on your computer’s motherboard. It acts as the intermediary between your operating system and the hardware components, initializing them during the boot process and providing low-level control. Keeping your BIOS up-to-date is essential for maintaining system stability, compatibility, and security. This article provides a comprehensive guide to understanding and updating the AOpen DE45-HG Bios R1.03, including its improvements, update methods, and precautions.
Understanding the AOpen DE45-HG Bios R1.03
The AOpen DE45-HG Bios R1.03 represents an update to the firmware specifically designed for the AOpen DE45-HG motherboard. These updates are often released by manufacturers to address various issues, enhance performance, or introduce new features. Before proceeding with the update, it’s crucial to understand the specific changes included in this version.
Key Improvements in Bios R1.03
According to the release notes, the AOpen DE45-HG Bios R1.03 incorporates the following key improvements:
-
Improved AC Power Lost Function Coverage: This enhancement aims to improve the system’s behavior when encountering unexpected power outages. A robust AC power loss function ensures that the system can gracefully handle power interruptions, minimizing the risk of data corruption or hardware damage. The update likely refines the power management algorithms and error handling routines to better manage these situations.
-
Removal of "Disable" Option in "Internal Graphics Mode Select": The removal of the "Disable" option within the "Internal Graphics Mode Select" setting suggests a change in how the integrated graphics are managed. This likely indicates a streamlining of the graphics configuration options, potentially removing an unnecessary setting that could lead to user confusion or misconfiguration. This could also be related to ensuring compatibility with certain operating systems or graphics drivers.
-
Support for WOL After AC Loss and Recovery: Wake-on-LAN (WOL) allows a computer to be powered on remotely over a network. This update enables WOL functionality even after the system experiences an AC power loss and subsequently recovers. This is a significant enhancement for systems that need to be remotely accessible, as it ensures that the WOL feature remains operational even after power interruptions. The update likely involves changes to the power management and network initialization routines.
Why Update Your BIOS?
Updating your BIOS can offer several benefits:
- Improved Stability: Updates often include bug fixes that can resolve system crashes, freezes, and other stability issues.
- Enhanced Compatibility: New BIOS versions can improve compatibility with newer hardware components, such as processors, memory modules, and graphics cards.
- Increased Security: BIOS updates can patch security vulnerabilities that could be exploited by malicious software.
- New Features: Some updates introduce new features, such as support for new operating systems or hardware technologies.
- Performance Improvements: In some cases, BIOS updates can optimize system performance.
Update Methods for the AOpen DE45-HG Bios R1.03
The release notes for the AOpen DE45-HG Bios R1.03 outline two primary methods for updating the BIOS: using a Windows-based flash tool (AFUWIN.EXE) and using a DOS-based utility (AFUDOS.EXE).
1. Windows-Based Update (AFUWIN.EXE)
AFUWIN.EXE is a Windows-based utility that simplifies the BIOS update process. Here’s how to use it:
-
Download the BIOS Update: Download the AOpen DE45-HG Bios R1.03 update package, which typically includes the AFUWIN.EXE utility and the BIOS ROM file (filename.ROM). You can find the download link here: https://www.techspot.com/drivers/driver/file/information/12535/

2. DOS-Based Update (AFUDOS.EXE)
AFUDOS.EXE is a DOS-based utility that requires creating a bootable DOS environment. This method is generally more complex than the Windows-based approach.
-
Download the BIOS Update: Download the AOpen DE45-HG Bios R1.03 update package.
-
Create a Bootable DOS Drive: Create a bootable DOS USB drive or CD-ROM. You can use tools like Rufus or similar utilities.
-
Copy the Files: Copy the AFUDOS.EXE utility and the BIOS ROM file (filename.ROM) to the bootable DOS drive.
-
Boot from the DOS Drive: Configure your computer to boot from the DOS drive. This usually involves changing the boot order in the BIOS settings.
-
Run AFUDOS.EXE: At the DOS prompt, type the following command and press Enter:
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./N
: Program the NVRAM./C
: Clear CMOS after programming.
-
Restart Your Computer: After the update is complete, restart your computer.
Important Precautions Before Updating
Before updating your BIOS, it’s crucial to take the following precautions:
- Back Up Your Existing BIOS: If possible, back up your current BIOS configuration. This allows you to revert to the previous version if something goes wrong during the update process. Some BIOS utilities have a built-in backup feature.
- Ensure a Stable Power Supply: A power interruption during the BIOS update process can corrupt the BIOS and render your system unusable. Ensure that your computer is connected to a stable power source or a UPS (Uninterruptible Power Supply).
- Close All Running Applications: Close all running applications before starting the BIOS update. This minimizes the risk of conflicts or interruptions.
- Read the Instructions Carefully: Carefully read and understand the instructions provided with the BIOS update package before proceeding.
- Use the Correct BIOS File: Make sure you are using the correct BIOS file for your motherboard model (AOpen DE45-HG). Using the wrong BIOS file can damage your system.
- Do Not Interrupt the Update: Do not interrupt the BIOS update process once it has started. This includes turning off the computer, unplugging the power cord, or pressing any keys.
Troubleshooting Common Issues
If you encounter problems during the BIOS update process, here are some common troubleshooting steps:
- Verify the BIOS File: Ensure that you have downloaded the correct BIOS file for your motherboard.
- Check the USB Drive: If using a USB drive, make sure it is properly formatted and bootable.
- Clear CMOS: If the update fails, try clearing the CMOS (Complementary Metal-Oxide-Semiconductor) memory. This can be done by removing the CMOS battery on the motherboard for a few minutes. Refer to your motherboard manual for instructions.
- Contact AOpen Support: If you are unable to resolve the issue, contact AOpen support for assistance.
