JetWay MA3-79GDG COMBO Bios DDR2-A04

This article provides information and instructions for updating the BIOS on the JetWay MA3-79GDG COMBO motherboard to version DDR2-A04. Updating your motherboard BIOS can improve system stability, compatibility, and performance. However, it’s crucial to follow the instructions carefully, as an incorrect BIOS update can render your motherboard unusable. This guide will walk you through the necessary steps, precautions, and changes included in this specific BIOS version.

Understanding the Importance of BIOS Updates

The BIOS (Basic Input/Output System) is firmware embedded on a small chip on your motherboard. It’s the first code that runs when you power on your computer, initializing hardware components and loading the operating system. BIOS updates often include:

  • Enhanced CPU Support: Newer processors might require updated BIOS code to function correctly.
  • Improved Memory Compatibility: Updates can improve compatibility with various RAM modules, especially newer or high-performance ones.
  • Bug Fixes: BIOS updates can address known issues and improve system stability.
  • Performance Enhancements: In some cases, updates can optimize performance, particularly in specific tasks or applications.

Cautionary Notes Before Proceeding

Before attempting to flash the BIOS on your JetWay MA3-79GDG COMBO motherboard, please read the following notices carefully:

  1. Clear CMOS After Flashing: After successfully flashing the BIOS, it is imperative to either load Optimized Defaults within the BIOS settings or clear the CMOS (Complementary Metal-Oxide-Semiconductor) memory. This ensures the system properly recognizes the new BIOS settings and prevents potential instability. Refer to your motherboard manual for instructions on clearing the CMOS, typically involving a jumper or button on the board.

  2. BIOS Upgrade Procedure: The recommended and safe BIOS upgrade procedure is as follows:

    • Flash the BIOS using the appropriate utility and version.
    • Enter the BIOS setup utility (usually by pressing DEL, F2, or another key during startup – consult your motherboard manual).
    • Load Optimized Defaults. This will reset the BIOS settings to factory-recommended values.
    • Save the changes and exit the BIOS setup. The system will then restart.

  3. AWARD Flash Utility Version: It is crucial to use the correct AWARD Flash Utility version. The recommended version is 8.83 or newer. Using an older version may lead to incomplete or corrupted BIOS flashing, potentially bricking your motherboard.

  4. SPI BIOS Considerations: Some motherboards utilize SPI (Serial Peripheral Interface) BIOS chips. Updating these motherboards with older AWARD Flash Utility versions can lead to system crashes and unrecoverable errors. Ensure you are using the correct and updated utility.

  5. AWDFLASH Parameters: When using AWDFLASH (version 8.83 or newer) to flash this BIOS version, the parameters "/cd/cp/ch/wb/qi" are required. This ensures a complete and accurate flash process.

  6. Specific Motherboard Series and Flash Tool: For the following motherboard series, it is mandatory to use the updated tool Award Flash 8.27B:

    • P4XFA
    • P4XFB
    • P4XFBU
    • P4XFCP
    • P4XFCU
    • P4XFM
    • P4XFMP
    • P4XFMU
    • V6DP
    • V6DU
    • V6FP
    • V6FU

What’s New in BIOS Version DDR2-A04?

This BIOS update for the JetWay MA3-79GDG COMBO motherboard includes the following improvements and fixes:

  1. Updated CPU Code: This update incorporates the latest CPU microcode, which may be necessary for compatibility with newer processors or to address known CPU-related issues.

  2. Refreshed AGESA Code: The DDR2 memory controller portion of the BIOS has been updated to AGESA (AMD Generic Encapsulated Software Architecture) version 3.3.2.3. The DDR3 memory controller portion of the BIOS has been updated to 6.1.1.0.2. AGESA is a crucial component that initializes and manages the system’s core functionalities, including memory. Updating AGESA can improve memory compatibility, stability, and performance.

  3. Floppy Drive BIOS Update Fix: This update resolves an issue that prevented BIOS updates from being performed using a floppy disk drive. While less common now, this fix ensures that users who still rely on floppy disks for BIOS updates can successfully flash the new version.

Flashing the BIOS: A Step-by-Step Guide

Disclaimer: Flashing the BIOS is a potentially risky procedure. Incorrectly flashing the BIOS can render your motherboard unusable. Proceed at your own risk, and ensure you have read and understood all the instructions before beginning.

  1. Download the BIOS File: Download the BIOS file (DDR2-A04) from the provided link or an alternative source. Ensure the file is compatible with your JetWay MA3-79GDG COMBO motherboard.

  2. Prepare a Bootable USB Drive or Floppy Disk: You will need a bootable USB drive or floppy disk to flash the BIOS. If using a USB drive, format it as FAT32.

  3. Extract the BIOS Files: Extract the contents of the downloaded ZIP file to the root of your bootable USB drive or floppy disk. This should include the BIOS file itself (usually with a .BIN or .ROM extension) and the AWARD Flash Utility (AWDFLASH.EXE). Make sure you have the correct version (8.83 or newer, or 8.27B for the specified motherboard series).

  4. Boot from the USB Drive or Floppy Disk: Restart your computer and enter the BIOS setup utility (usually by pressing DEL, F2, or another key during startup – consult your motherboard manual). Change the boot order to prioritize booting from the USB drive or floppy disk.

  5. Run the AWARD Flash Utility: After booting from the USB drive or floppy disk, you should be at a command prompt. Type AWDFLASH.EXE followed by the name of the BIOS file and the required parameters /cd/cp/ch/wb/qi (if using version 8.83 or newer, and not flashing one of the motherboards requiring 8.27B). For example: AWDFLASH.EXE MA379GDG.BIN /cd/cp/ch/wb/qi. Press Enter to begin the flashing process. If you are using AWARD Flash 8.27B, you will likely have a graphical interface, and the parameters are not needed.

  6. Follow the On-Screen Instructions: The AWARD Flash Utility will guide you through the flashing process. Do not interrupt the process, turn off the computer, or reset the system while the BIOS is being flashed.

  7. Verify the Flash: After the flashing process is complete, the utility will typically prompt you to restart the computer.

  8. Load Optimized Defaults or Clear CMOS: After the restart, enter the BIOS setup utility again. Load Optimized Defaults or clear the CMOS as instructed in the "Cautionary Notes" section above.

  9. Save and Exit: Save the changes and exit the BIOS setup utility. The system will restart, and your updated BIOS should now be active.

Troubleshooting

  • System Won’t Boot After Flash: If your system fails to boot after flashing the BIOS, try clearing the CMOS. If that doesn’t work, you may need to recover the BIOS using a backup BIOS chip (if your motherboard has one) or a specialized BIOS recovery procedure. Consult your motherboard manual for details.
  • Flashing Utility Errors: Ensure you are using the correct version of the AWARD Flash Utility and that the BIOS file is compatible with your motherboard. Double-check the command-line parameters.
  • Incorrect BIOS File: Using the wrong BIOS file for your motherboard can lead to irreversible damage. Verify the file name and checksum before flashing.

This guide provides comprehensive instructions for updating the BIOS on your JetWay MA3-79GDG COMBO motherboard. By carefully following these steps and taking the necessary precautions, you can safely update your BIOS and enjoy the benefits of the latest improvements and fixes. Remember, proceed at your own risk, and always consult your motherboard manual for specific instructions and troubleshooting tips.
