This article provides information regarding the ASRock A790GMH/128M Bios version 1.20 specifically designed for Windows operating systems. It outlines the update procedure, important precautions, and the enhancements included in this particular BIOS revision. Understanding these details is crucial for users considering updating their ASRock A790GMH/128M motherboard’s BIOS to version 1.20.
Understanding the BIOS and Its Importance
The Basic Input/Output System (BIOS) is a fundamental piece of firmware embedded on a computer’s motherboard. It’s the first software to run when a computer is powered on. Its primary function is to initialize hardware components and load the operating system. The BIOS plays a critical role in system stability, hardware compatibility, and overall performance.
Updating the BIOS can provide several benefits, including:
- Improved Hardware Compatibility: New BIOS versions often include support for newer CPUs, memory modules, and other hardware components.
- Enhanced System Stability: BIOS updates can address bugs and glitches that may cause system instability or crashes.
- Performance Optimizations: Some BIOS updates include optimizations that can improve system performance.
- Security Updates: BIOS updates can patch security vulnerabilities, protecting the system from potential threats.
However, BIOS updates also carry a risk. A failed update can render the motherboard unusable, requiring professional service to recover. Therefore, it’s essential to proceed with caution and follow the instructions carefully.
ASRock A790GMH/128M Bios 1.20: What’s New?
BIOS version 1.20 for the ASRock A790GMH/128M motherboard includes the following key changes:
- Change Default Setting: This indicates that some default configurations within the BIOS have been modified. While the specific nature of these changes isn’t explicitly stated, it’s likely related to improving compatibility, stability, or performance. Users should review the BIOS settings after the update to understand the new default configurations and adjust them as needed.
- Update CPU Code: This refers to updating the CPU microcode, which is a small piece of firmware that resides on the CPU itself. CPU microcode updates are often released to address bugs, improve compatibility with specific CPUs, or enhance performance. This update ensures that the ASRock A790GMH/128M motherboard is running the latest and most stable CPU microcode available.
These changes collectively contribute to a more refined and stable user experience with the ASRock A790GMH/128M motherboard.
Updating the BIOS Under Windows Vista
The provided instructions detail how to update the ASRock A790GMH/128M Bios under Windows Vista. The instructions are very basic, but the process generally applies to other Windows operating systems as well, although the specific utility and file names may vary. Here’s a more detailed explanation:
-
Locate the AFUWIN.exe Utility: AFUWIN.exe is a command-line utility used to flash (update) the BIOS. It’s typically included in the BIOS update package downloaded from the ASRock website.
-
Run as Administrator: Right-click the AFUWIN.exe file and select "Run as administrator." This is crucial because the BIOS update process requires elevated privileges to access and modify the motherboard’s firmware. Failure to run as administrator may result in the update failing or causing errors.
Important Considerations Before Updating:
- Download the Correct BIOS Version: Ensure that you download the correct BIOS version for your specific motherboard model (ASRock A790GMH/128M in this case). Using the wrong BIOS version can damage your motherboard.
- Backup Your Existing BIOS (If Possible): Some BIOS flashing utilities allow you to back up your existing BIOS before updating. This can be a lifesaver if the update fails, as you can revert to the previous version.
- Disable Antivirus Software: Antivirus software can sometimes interfere with the BIOS update process. It’s recommended to temporarily disable your antivirus software before proceeding.
- Ensure a Stable Power Supply: A power outage during the BIOS update process can corrupt the BIOS and render the motherboard unusable. Make sure your computer is connected to a stable power source, preferably a UPS (Uninterruptible Power Supply).
- Close All Other Applications: Close all other applications running on your computer to minimize the risk of interference during the update process.
What to Do If Problems Arise
The provided "Notice" highlights the critical importance of avoiding interruptions during the BIOS update.
-
Do Not Turn Off Your System: If you encounter problems during the update, DO NOT turn off your computer. This can corrupt the BIOS and prevent your system from booting.
-
Repeat the Process: If the update fails, try repeating the process. Ensure that you have followed all the instructions correctly and that there are no potential sources of interference.
-
Update the Original BIOS File: If the problem persists, attempt to update with the original BIOS file. This assumes you have a backup of the original BIOS or can download it from the ASRock website.
-
Seek Professional Service: If the Flash Memory Writer utility fails to successfully update the BIOS, your system may not be able to boot. In this situation, your system will likely require professional service. This may involve sending the motherboard back to ASRock or taking it to a qualified computer repair technician who has the tools and expertise to recover a corrupted BIOS.
