This article provides information about the JetWay PN78VM2 Bios A03 update, outlining its key features, upgrade instructions, and important considerations for a successful and safe BIOS flashing process. Understanding these details is crucial for users looking to enhance their system’s compatibility and performance.
Overview of the JetWay PN78VM2 Bios A03 Update
The JetWay PN78VM2 Bios A03 update is a firmware revision designed to improve the functionality and compatibility of the JetWay PN78VM2 motherboard. The primary focus of this update is to enhance CPU support, specifically for older generation AMD processors.
Key Improvements:
- Updated CPU Code: The BIOS update incorporates CPU code updates, specifically upgrading from AGESA 3.1.9.0 to AGESA 3.3.2.0. AGESA (AMD Generic Encapsulated System Architecture) is a crucial component that initializes the CPU and chipset during the boot process. Updates to AGESA often bring enhanced compatibility and performance improvements.
- Expanded CPU Support: This update introduces support for the AMD Phenom II 920 and Phenom II 940 CPUs. These processors were popular choices for gaming and general computing when they were first released. Users with these CPUs installed on the JetWay PN78VM2 motherboard will need this BIOS update to ensure proper functionality.
Important Considerations Before Flashing
Before proceeding with the BIOS update, it’s imperative to understand the risks involved and follow the instructions precisely. A failed BIOS flash can render the motherboard unusable, requiring specialized equipment and expertise to recover.
Critical Notices:
- Load Optimized Defaults or Clear CMOS: After flashing the BIOS, it is mandatory to either load Optimized Defaults within the BIOS setup utility or clear the CMOS. This step ensures that the new BIOS settings are properly applied and that the system operates stably. Failing to do so can result in unpredictable behavior or boot failures. Clearing the CMOS can typically be done by either using a jumper on the motherboard or by temporarily removing the CMOS battery while the system is powered off.
- BIOS Upgrade Procedure: The recommended BIOS upgrade procedure is as follows:
- Flash BIOS: Use the appropriate flashing utility to update the BIOS.
- Enter BIOS: Restart the computer and enter the BIOS setup utility (usually by pressing DEL, F2, or another key during startup, as indicated on the boot screen).
- Load Optimized Defaults: Within the BIOS setup, locate the option to load Optimized Defaults. This resets all BIOS settings to their default values, ensuring compatibility with the new BIOS version.
- Save and Exit: Save the changes and exit the BIOS setup. The system will then restart.
- AWARD Flash Utility Version: The update process requires the use of the AWARD Flash Utility. It is crucial to use version 8.83 or newer of this utility to avoid potential issues. Older versions may not be fully compatible with the PN78VM2 motherboard and could lead to a failed flash.
- SPI BIOS Considerations: Some revisions of the JetWay PN78VM2 motherboard may incorporate an SPI (Serial Peripheral Interface) BIOS. Using an older version of the AWARD Flash Utility on these motherboards can potentially cause a system crash during the update process. Therefore, ensuring the correct utility version is paramount.
- AWDFLASH Parameters: When using the AWDFLASH utility (version V8.83 or newer) to flash the BIOS, specific parameters are required:
/cd/cp/ch/wb/qi. These parameters are command-line switches that instruct the flashing utility on how to properly update the BIOS. Omitting these parameters may result in an incomplete or corrupted flash. - Specific Motherboard Series Tool: Certain motherboard series require a specific version of the Award Flash tool. These include the P4XFA, P4XFB, P4XFBU, P4XFCP, P4XFCU, P4XFM, P4XFMP, P4XFMU, V6DP, V6DU, V6FP, and V6FU. These motherboards should use the updated tool Award Flash 8.27B.
Downloading the BIOS Update

Preparation:
- Download the BIOS file: Download the JetWay PN78VM2 Bios A03 file from the provided link or an alternative source.
- Download the AWARD Flash Utility: Download version 8.83 or newer of the AWARD Flash Utility. If your motherboard is one of the specific series listed above, download Award Flash 8.27B instead.
- Prepare a Bootable USB Drive: Create a bootable USB drive. You can use tools like Rufus or the Windows command prompt to create a bootable drive.
- Copy Files to USB Drive: Copy the BIOS file and the AWARD Flash Utility to the bootable USB drive.
-
Boot from USB Drive:
- Restart your computer and enter the BIOS setup utility (usually by pressing DEL, F2, or another key during startup).
- Configure the BIOS to boot from the USB drive. The specific settings may vary depending on your BIOS version.
-
Flash the BIOS:
-
After booting from the USB drive, you will be presented with a command prompt.
-
Navigate to the directory where you copied the BIOS file and the AWARD Flash Utility.
-
Run the AWARD Flash Utility with the following command (replace "PN78VM2A03.BIN" with the actual name of your BIOS file):
AWDFLASH PN78VM2A03.BIN /cd/cp/ch/wb/qi -
The flashing process will begin. Do not interrupt the process. Power outages or accidental shutdowns during the flash can corrupt the BIOS and render the motherboard unusable.
-
The utility will verify the flash and prompt you to restart the computer.
-
-
Post-Flash Configuration:
- After the system restarts, immediately enter the BIOS setup utility.
- Load Optimized Defaults: Locate and select the option to load Optimized Defaults.
- Save and Exit: Save the changes and exit the BIOS setup.
- The system will restart again. Verify that the BIOS update was successful by checking the BIOS version displayed during startup.
Troubleshooting
- System Won’t Boot: If the system fails to boot after the flash, try clearing the CMOS. If that doesn’t work, the BIOS may be corrupted. You may need specialized equipment to re-flash the BIOS using a hardware programmer.
- Incorrect BIOS Version Displayed: If the BIOS version displayed during startup is incorrect, repeat the flashing process. Ensure that you are using the correct BIOS file and AWARD Flash Utility.
- System Instability: If the system is unstable after the flash, try adjusting the BIOS settings. Ensure that your CPU and memory are running at their correct speeds and voltages.
