This article focuses on BIOS version 2.20 for the ASRock 939Dual-SATA2, exploring its significance, features, and how to obtain and update it.

Understanding the BIOS

The BIOS is a firmware program embedded on a small chip on the motherboard. It’s the first software that runs when a computer is powered on. Its primary functions include:

• POST (Power-On Self-Test): Performing a diagnostic check of the system’s hardware components to ensure they are functioning correctly.
• Bootstrapping: Locating and loading the operating system from a storage device (hard drive, SSD, etc.).
• Hardware Abstraction: Providing a low-level interface for the operating system to interact with hardware devices.
• Configuration: Allowing users to configure hardware settings, such as boot order, CPU frequency, memory timings, and more.

Significance of BIOS Updates

BIOS updates are crucial for several reasons:

• Bug Fixes: Addressing known issues and errors that can cause instability or malfunctions.
• Hardware Compatibility: Enabling support for newer hardware components, such as CPUs, memory modules, and storage devices.
• Performance Improvements: Optimizing system performance by improving hardware handling and resource management.
• Security Enhancements: Patching security vulnerabilities that could be exploited by malicious software.
• Feature Additions: Introducing new features and functionalities, such as support for advanced power management or new storage technologies.

Obtaining and Updating the BIOS

Updating the BIOS is a critical process that should be performed with caution. A failed BIOS update can render the motherboard unusable. Here’s a general guide:

1. Identify Your Motherboard Revision: Ensure you have the correct BIOS version for your specific motherboard revision. Incorrect BIOS files can cause serious damage.

2. Download the BIOS File: The primary download link for ASRock 939Dual-SATA2 Bios 2.20 is: https://www.techspot.com/drivers/driver/file/information/7748/

3. Alternative Download Links: Due to the age of the motherboard, finding the BIOS file might be challenging. Here are some alternative sources, although availability may vary:

   • Archive.org (Wayback Machine): Search for the ASRock 939Dual-SATA2 support page on Archive.org. Older versions of the website might contain the BIOS file.
   • Driver Download Sites: Websites like Softpedia or DriverGuide may host older drivers and BIOS files. Be cautious and only download from reputable sources.
   • ASRock Support Forums: Check ASRock’s official or unofficial support forums. Other users may have uploaded the BIOS file or can provide assistance.
   • Third-Party Hardware Archives: Some hardware enthusiast websites maintain archives of older drivers and BIOS files.
   • Hardware Identification Websites: Some websites offer driver and BIOS downloads after identifying the hardware on your computer.

4. Prepare a Bootable USB Drive or Floppy Disk: The BIOS update utility typically requires a bootable USB drive or floppy disk. Follow the instructions provided by ASRock for creating a bootable media.

5. Copy the BIOS File and Update Utility: Copy the downloaded BIOS file and the BIOS update utility (usually included in the download package) to the bootable media.

6. Boot from the USB Drive or Floppy Disk: Restart your computer and enter the BIOS setup utility (usually by pressing DEL, F2, or F12 during startup). Configure the BIOS to boot from the USB drive or floppy disk.

7. Run the BIOS Update Utility: Once the computer boots from the bootable media, run the BIOS update utility. Follow the on-screen instructions carefully.

8. Do Not Interrupt the Process: It is crucial not to interrupt the BIOS update process. Do not turn off the computer or unplug the power cord.

9. Restart the Computer: After the BIOS update is complete, the computer will automatically restart.

10. Verify the Update: Enter the BIOS setup utility again and verify that the BIOS version has been updated to version 2.20.

Risks and Precautions

Updating the BIOS carries inherent risks. A failed update can render the motherboard unusable, requiring specialized equipment to recover. Before proceeding, consider the following precautions:

• Ensure a Stable Power Supply: Use a UPS (Uninterruptible Power Supply) to protect against power outages during the update process.
• Read the Instructions Carefully: Follow the instructions provided by ASRock precisely.
• Back Up Your Existing BIOS: If possible, back up your current BIOS settings before starting the update.
• Do Not Update Unnecessarily: Only update the BIOS if you are experiencing specific issues that the update is known to address. If your system is stable and functioning correctly, there may be no need to update.
• Research Thoroughly: Research the BIOS update and any potential issues reported by other users.
