By Posted on

This document provides information regarding the JetWay PA78VM2 motherboard BIOS update, version A03. This update addresses specific issues and enhances the motherboard’s compatibility with certain hardware components. It is crucial to carefully follow the instructions outlined below to ensure a successful and safe BIOS update. Incorrectly flashing the BIOS can lead to system instability or even permanent damage.

Understanding the BIOS and its Importance

The BIOS (Basic Input/Output System) is a fundamental piece of software embedded on a motherboard. It’s the first code that runs when a computer is powered on, responsible for initializing hardware components, performing a power-on self-test (POST), and loading the operating system. A BIOS update can improve system stability, enhance compatibility with new hardware, fix bugs, and sometimes even improve performance.

Important Notices Before Proceeding

Before attempting to flash the JetWay PA78VM2 BIOS to version A03, please carefully review the following notices. These instructions are critical for a successful and safe update.

  1. Post-Flash Procedure: After successfully flashing the BIOS, it is imperative to either load Optimized Defaults or clear the CMOS. This ensures the system properly recognizes and configures the updated BIOS settings. Failing to do so can lead to instability and unexpected behavior.

  2. BIOS Upgrade Steps: The recommended procedure for upgrading the BIOS 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 essential to use AWARD Flash Utility version 8.83 or a newer version when flashing the BIOS. Using an older version may result in errors or an incomplete flash.

  4. SPI BIOS Warning: Certain motherboards incorporating SPI BIOS may experience system crashes if updated with older versions of the AWARD Flash Utility. Please exercise caution and ensure the correct version is used.

  5. AWDFLASH Parameters: When using AWDFLASH (version 8.83 or newer) to update this BIOS version, the "/cd/cp/ch/wb/qi" parameters are required. These parameters ensure the flash utility correctly handles the BIOS image and avoids potential errors.

  6. Specific Motherboard Series and AWARD Flash 8.27B: The following motherboard series require the use of the updated Award Flash 8.27B tool: P4XFA, P4XFB, P4XFBU, P4XFCP, P4XFCU, P4XFM, P4XFMP, P4XFMU, V6DP, V6DU, V6FP, and V6FU. If you own one of these motherboards, using a different flash utility could cause irreversible damage. The JetWay PA78VM2 Bios A03 update is not for these boards.

What’s New in JetWay PA78VM2 Bios A03

This BIOS update includes the following improvements and fixes:

  1. Graphics Card Bug Fix: Resolves an issue where a graphics card installed in the PE1 slot would fail to function correctly when RTM 880N-790 clockgen values were modified. This fix improves compatibility and stability for users who adjust clockgen settings.

  2. Hynix 2G Memory Support: Updates the BIOS code to provide enhanced support for Hynix 2GB memory modules. This improvement ensures proper detection and operation of these memory modules, potentially resolving compatibility issues or improving performance. This is a crucial update for users utilizing Hynix 2GB memory on their JetWay PA78VM2.

  2. Booting into DOS:

    • Insert the bootable USB drive into the computer.
    • Power on the computer and enter the BIOS setup utility (usually by pressing DEL, F2, or F12 during startup).
    • Configure the BIOS to boot from the USB drive.
    • Save the changes and exit the BIOS setup. The computer will restart and boot into the DOS environment.

  3. Flashing the BIOS:

    • At the DOS prompt, navigate to the USB drive (usually by typing C: or D: and pressing Enter).
    • Type the command to run the AWARD Flash Utility, including the BIOS filename and the required parameters (e.g., AWDFLASH PA78VM2A03.BIN /cd/cp/ch/wb/qi). Replace PA78VM2A03.BIN with the actual filename of the BIOS update file.
