Important Notices Before Proceeding

Before you begin the BIOS flashing process for your JetWay PA78GM5, it’s essential to understand and adhere to the following instructions:

  1. Clear CMOS or Load Optimized Defaults: After flashing the BIOS, it’s imperative to either load "Optimized Defaults" in the BIOS setup or clear the CMOS. This step ensures that the system recognizes the new BIOS settings and operates correctly. Failure to do so can result in instability or boot failures.

  2. BIOS Upgrade Procedure: The recommended BIOS upgrade process is as follows:

    • Flash the BIOS using the appropriate utility.
    • Enter the BIOS setup utility.
    • Load "Optimized Defaults".
    • Save the changes and exit the BIOS setup.

  3. AWARD Flash Utility Version: It is strongly recommended to use AWARD Flash Utility version 8.83 or newer for this BIOS update. Using an older version could lead to complications.

  4. SPI BIOS Caution: Some motherboards utilizing SPI BIOS chips are susceptible to system crashes when updated with older versions of the AWARD Flash Utility. Exercise caution and ensure you’re using the recommended version.

  5. AWDFLASH Parameters: When using AWDFLASH (version 8.83 or newer) to update this BIOS version, the parameters "/cd/cp/ch/wb/qi" are required. These parameters are crucial for a successful flash.

  6. Specific Motherboard Series and Award Flash 8.27B: The following motherboard series should specifically use the updated tool Award Flash 8.27B: (P4XFA P4XFB P4XFBU P4XFCP P4XFCU P4XFM P4XFMP P4XFMU V6DP V6DU V6FP V6FU). This is important for compatibility and to prevent issues during the flashing process.

BIOS Flashing Procedure: A Detailed Guide

Disclaimer: Flashing the BIOS is a potentially risky procedure. Incorrectly flashing the BIOS can render your motherboard unusable. Proceed at your own risk. Ensure you have a stable power supply and avoid interrupting the process.

  1. Preparation:

    • Identify your Motherboard Revision: Confirm that you have the JetWay PA78GM5 motherboard. Check the motherboard itself or the original packaging.
    • Download the BIOS File: Download the JetWay PA78GM5 BIOS A03 file from the provided link or a trusted alternative.
    • Extract the Files: Extract the contents of the downloaded ZIP file to a temporary folder on your computer.
    • Obtain AWARD Flash Utility: If you don’t already have it, download AWARD Flash Utility version 8.83 or newer (or Award Flash 8.27B for the specified motherboard series). You can typically find this utility on driver download websites or by searching online.
    • Create a Bootable USB Drive (Recommended): A bootable USB drive is the safest and most reliable method for flashing the BIOS. You can use tools like Rufus to create a bootable USB drive with DOS. Copy the extracted BIOS file and the AWARD Flash Utility to the USB drive.

  2. Booting into DOS:

    • Insert the bootable USB drive into your computer.
    • Restart your computer.
    • Enter the BIOS setup utility (usually by pressing DEL, F2, or F12 during startup).
    • Configure the boot order to prioritize the USB drive.
    • Save the changes and exit the BIOS setup. Your computer will now boot from the USB drive into DOS.

  3. Flashing the BIOS:

    • At the DOS prompt, navigate to the directory where you copied the BIOS file and the AWARD Flash Utility.
    • Type the following command (replace "PA78GM5A03.BIN" with the actual name of the BIOS file): 
      AWDFLASH PA78GM5A03.BIN /cd/cp/ch/wb/qi

      Important: Ensure you include the "/cd/cp/ch/wb/qi" parameters as specified in the original notice.
      If you are using Award Flash 8.27B you do not need these parameters

    • Press Enter. The AWARD Flash Utility will begin the BIOS flashing process.
    • Do not interrupt the process. Wait for the utility to complete the flashing process and display a success message. This may take a few minutes.

  4. Post-Flashing Steps:

    • Once the flashing process is complete, restart your computer.
    • Enter the BIOS setup utility again.
    • Load "Optimized Defaults". This is a crucial step.
    • Save the changes and exit the BIOS setup.

Troubleshooting

  • System Won’t Boot After Flashing: If your system fails to boot after flashing, try clearing the CMOS. Locate the CMOS jumper on your motherboard (refer to your motherboard manual) and move it to the "clear" position for a few seconds. Then, return it to the normal position and try booting again.
  • Flashing Utility Errors: Double-check that you are using the correct version of the AWARD Flash Utility and that you have included the necessary parameters. Also, ensure that the BIOS file is not corrupted.
  • Incompatible Memory: If you experience issues after updating the BIOS, especially related to memory, ensure that your memory modules are compatible with the motherboard. Consult the motherboard’s manual for a list of supported memory modules.

Conclusion

Updating the JetWay PA78GM5 Bios A03 can address specific bugs and improve system compatibility, particularly with graphics cards and Hynix 2GB memory. However, it’s crucial to follow the instructions carefully and take necessary precautions to avoid potential problems. Remember to use the correct AWARD Flash Utility, include the required parameters, and load "Optimized Defaults" after flashing. By following this guide, you can increase your chances of a successful BIOS update and improve the performance and stability of your JetWay PA78GM5-based system. This JetWay PA78GM5 Bios A03 update is important for users experiencing the aforementioned issues.
