JetWay MA3-79GDG COMBO Bios A03

This article provides information regarding the JetWay MA3-79GDG COMBO motherboard BIOS update A03. This update includes several modifications and fixes designed to improve system stability and performance. It is crucial to follow the instructions outlined below carefully to ensure a successful BIOS flash and prevent potential system issues.

Understanding the BIOS

The Basic Input/Output System (BIOS) is a fundamental piece of software embedded within a computer’s motherboard. It’s the first program that runs when you power on your computer, initializing hardware components and providing essential services for the operating system to load. Updating the BIOS can resolve compatibility issues, improve performance, and enable support for newer hardware.

Important Precautions Before Flashing the BIOS

Before proceeding with the BIOS update, it is imperative to understand the risks involved. A failed BIOS flash can render your motherboard unusable, requiring professional repair or replacement. Therefore, ensure you have a stable power supply and follow the instructions meticulously.

The original manufacturer provides several critical warnings, which must be heeded:

  1. Load Optimized Defaults/Clear CMOS is Mandatory: After successfully flashing the BIOS, it is essential to either load optimized defaults within the BIOS setup utility or clear the CMOS (Complementary Metal-Oxide-Semiconductor) memory. This ensures that the system recognizes the new BIOS settings and operates correctly. Failure to do so may result in instability or boot failures. The CMOS memory stores BIOS settings, and clearing it resets these settings to their default values.

  2. BIOS Upgrade Procedure: The recommended BIOS upgrade procedure consists of the following steps:

    • Flash BIOS: Initiate the BIOS flashing process using the appropriate utility.
    • Enter into BIOS: After the flash completes, access the BIOS setup utility, typically by pressing a key like Delete, F2, or F12 during startup (the specific key varies by motherboard manufacturer).
    • Load Optimized Defaults: Within the BIOS setup, locate the option to "Load Optimized Defaults" or a similar phrase and select it.
    • Save and Exit: Save the changes and exit the BIOS setup. The system will then reboot.

  3. AWARD Flash Utility Version Requirement: It is crucial to use the correct version of the AWARD Flash Utility to perform the BIOS update. The manufacturer explicitly states that version 8.83 or newer of the AWARD Flash Utility is required. Using an older version may lead to compatibility issues or a failed flash.

  4. SPI BIOS Compatibility: Some motherboards utilize Serial Peripheral Interface (SPI) BIOS chips. Updating these motherboards with older versions of the AWARD Flash Utility can potentially cause a system crash and render the motherboard unusable. Therefore, adhering to the recommended utility version is paramount.

  5. AWDFLASH Parameters: When using the AWDFLASH utility (version 8.83 or newer) to update the BIOS for the JetWay MA3-79GDG COMBO, specific parameters are required. These parameters are "/cd/cp/ch/wb/qi". These parameters likely control specific aspects of the flashing process, such as clearing the CMOS or verifying the BIOS image. The use of these parameters is essential for a successful update.

  6. Specific Motherboard Series and Award Flash 8.27B: The manufacturer lists a series of older motherboards (P4XFA P4XFB P4XFBU P4XFCP P4XFCU P4XFM P4XFMP P4XFMU V6DP V6DU V6FP V6FU) that require the use of Award Flash 8.27B. This warning does not apply to the JetWay MA3-79GDG COMBO; however, it is important to be aware of if you are working with other older JetWay motherboards.

What’s New in BIOS A03

The BIOS A03 update for the JetWay MA3-79GDG COMBO includes the following improvements:

  1. Modified BIOS Message: This likely refers to a change in the text displayed during the boot process, potentially including updated copyright information or other minor adjustments.

  2. CPU Speed Fix: The update resolves an issue where the CPU speed would not change after adjusting the CPU ratio within the BIOS settings. This is a significant fix, as it allows users to properly overclock or underclock their CPUs as desired. Without this fix, changes to the CPU ratio would be ignored, preventing users from achieving their desired CPU performance.

  3. CPU Ratio and FID Functionality: The update adds support for CPU Ratio and FID (Frequency ID) functions within the BIOS. These functions allow users to fine-tune the CPU’s operating frequency and voltage, enabling more precise control over performance and power consumption. This feature is particularly useful for overclocking enthusiasts who want to push their CPUs to their limits.
