This article provides information regarding the JetWay PN78SM3-HL motherboard BIOS update, specifically version A05. This update incorporates significant improvements and compatibility enhancements, particularly concerning CPU support. This guide will walk you through the changes included in the update, the necessary precautions, and the recommended procedure for flashing your BIOS. This update is crucial for users looking to optimize their system’s performance and ensure compatibility with newer processors.

Understanding the JetWay PN78SM3-HL Bios A05 Update

The JetWay PN78SM3-HL Bios A05 update brings several key improvements to the motherboard. The most significant change is the update to the CPU code.

What’s New in A05:

  • CPU Code Update: The BIOS updates the CPU code from AGESA 3.1.9.0 to AGESA 3.3.2.0. This update enables support for AMD Phenom II 920 and 940 processors.

This enhancement is essential for users who intend to upgrade or are already using these specific Phenom II processors. The updated AGESA (AMD Generic Encapsulated System Architecture) code ensures optimal performance, stability, and proper functionality with these CPUs. The JetWay PN78SM3-HL benefits significantly from this compatibility update.

Important Considerations Before Flashing

Before proceeding with the BIOS update, it’s crucial to understand the potential risks and follow the recommended guidelines. Incorrectly flashing the BIOS can render your motherboard unusable, so proceed with caution and ensure you have a stable power supply.

Critical Notices:

  1. Load Optimized Defaults or Clear CMOS: After flashing the BIOS, it is imperative to load Optimized Defaults in the BIOS settings or clear the CMOS. This step ensures that the new BIOS settings are properly applied and that the system operates correctly. Failure to do so may result in instability or boot failures.

  2. BIOS Upgrade Procedure: The recommended BIOS upgrade procedure 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.

  3. AWARD Flash Utility Version: Ensure that you are using AWARD Flash Utility version 8.83 or a newer version before upgrading your BIOS. Using an older version may lead to compatibility issues or flashing errors.

  4. SPI BIOS and Potential System Crash: Some motherboards, particularly those incorporating SPI (Serial Peripheral Interface) BIOS, may experience system crashes if updated with older versions of the AWARD Flash Utility. Therefore, using the recommended version is critical to prevent damage.

  5. AWDFLASH Parameters: When using AWDFLASH (it’s highly recommended to use a version newer than V8.83) to update the BIOS, specific parameters are required. The parameters "/cd/cp/ch/wb/qi" must be included in the command line. This ensures that the flashing process is executed correctly.

  6. Specific Motherboard Series and Award Flash 8.27B: The following motherboard series must use the updated tool Award Flash 8.27B:

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

Step-by-Step Guide to Flashing the BIOS

Flashing the BIOS can seem daunting, but by following these steps carefully, you can minimize the risk of errors:

  1. Download the BIOS Update: Obtain the JetWay PN78SM3-HL Bios A05 update from a trusted source, such as the manufacturer’s website or a reputable driver repository.

  2. Prepare a Bootable USB Drive: You’ll need a bootable USB drive to flash the BIOS. Several tools are available to create bootable USB drives, such as Rufus or the Windows USB/DVD Download Tool. Format the USB drive as FAT32.

  3. Copy the BIOS Files and Flash Utility: Extract the contents of the downloaded BIOS update package to the root directory of the bootable USB drive. Ensure that the AWARD Flash Utility (version 8.83 or newer) is also present on the USB drive.

  4. Boot from the USB Drive: Restart your computer and enter the BIOS setup utility (usually by pressing DEL, F2, or F12 during startup). Configure the boot order to prioritize booting from the USB drive.

  5. Run the Flash Utility: Once the computer boots from the USB drive, you’ll be presented with a command prompt. Navigate to the directory where the BIOS files and flash utility are located (usually the root directory).

  6. Execute the Flash Command: Run the AWARD Flash Utility with the appropriate parameters. The command will typically look something like this:

    AWDFLASH [BIOS Filename] /cd/cp/ch/wb/qi

    Replace [BIOS Filename] with the actual name of the BIOS file (e.g., PN78SM3.A05).

  7. Wait for the Flashing Process to Complete: The flash utility will now begin the process of writing the new BIOS to the motherboard’s EEPROM. Do not interrupt the process or turn off the computer during this time. Interrupting the process can lead to a corrupted BIOS and an unusable motherboard.

  8. Restart the Computer: Once the flashing process is complete, the utility will prompt you to restart the computer. Remove the USB drive and allow the computer to reboot.

  9. Enter the BIOS Setup Utility: After the computer restarts, enter the BIOS setup utility again.

  10. Load Optimized Defaults: Navigate to the option to load Optimized Defaults (or similar wording) and select it.

  11. Save and Exit: Save the changes and exit the BIOS setup utility. The computer will restart again.

  12. Verify the BIOS Version: After the final restart, enter the BIOS setup utility one more time to verify that the BIOS version has been successfully updated to A05.

Troubleshooting Common Issues

If you encounter any issues during or after the BIOS update, here are some common problems and their solutions:

  • System Fails to Boot: If the system fails to boot after flashing the BIOS, ensure that you have loaded Optimized Defaults or cleared the CMOS. If the problem persists, you may need to try reflashing the BIOS using a different method or a different version of the flash utility.

  • Flashing Process Fails: If the flashing process fails, ensure that you are using the correct version of the AWARD Flash Utility and that the BIOS file is not corrupted. Also, check that the USB drive is properly formatted and bootable.

  • Incompatible CPU: While this update is designed to support Phenom II 920 and 940 CPUs, make sure your CPU is indeed compatible with the JetWay PN78SM3-HL motherboard before flashing. Refer to the motherboard’s documentation or the manufacturer’s website for a list of supported CPUs.
