JetWay BA-500PRO1 Bios A03_W

This document provides information regarding the JetWay BA-500PRO1 motherboard BIOS update A03_W. This update includes important improvements, bug fixes, and new features designed to enhance system stability and performance. This article will detail the changes included in this BIOS version and provide clear instructions on how to properly update your motherboard’s BIOS.

Important Considerations Before Updating:

Before proceeding with the BIOS update, it is crucial to understand the potential risks involved. A failed BIOS update can render your motherboard unusable. Therefore, it is essential to follow the instructions carefully and ensure a stable power supply throughout the process. Consider these warnings from JetWay:

• Load Optimized Defaults/Clear CMOS: After flashing the BIOS, loading optimized defaults or clearing the CMOS is mandatory to ensure the system operates correctly. This step resets the BIOS settings to their default values, resolving potential conflicts caused by the new BIOS version.
• BIOS Upgrade Sequence: The recommended upgrade sequence is as follows:
  1. Flash the BIOS.
  2. Enter the BIOS setup utility.
  3. Load Optimized Defaults.
  4. Save changes and exit.
• Flash Utility: Use the correct flash utility. The JetWay BA-500PRO1 Bios A03_W requires either the AWARD Flash Utility or the AMI Flash Utility.
• Flash Utility Version: Ensure you are using the appropriate version of the flash utility. It’s recommended to use AWARD Flash Utility Ver. 8.83 or newer, or AMI Flash Utility Ver. 4.29 or newer.
• Command Line Parameters: When using AWDFLASH (version V8.83 or newer), the following parameters are required: "/cd/cp/ch/wb/qi". When using AMIFLASH (version V4.29 or newer), the following parameters are required: "/p /b/n /c /k". Using the correct parameters ensures a successful and complete flash.
• BIOS Type Compatibility: Award BIOS cannot be updated with AMI BIOS and vice versa. Make sure you’re using the right one.

What’s New in the JetWay BA-500PRO1 Bios A03_W Update:

This BIOS update introduces several key improvements and fixes, addressing specific user needs and enhancing overall system functionality.

1. CPU Core Disabling Function: A new function has been added to allow users to disable specific CPU cores. This can be useful for troubleshooting, power saving, or specific application requirements where fewer cores are preferred.
2. Sideport Memory Clock Options: The BIOS now supports higher clock options for sideport memory, exceeding 667 MHz. This allows for greater memory bandwidth and improved integrated graphics performance, if applicable.
3. USB Keyboard Startup Bug Fix: This update resolves a bug that caused the system to fail to start when using a USB keyboard. This ensures that users can reliably boot their systems with a USB keyboard connected.
4. Power On After Power Fail Function: The "Power On After Power Fail" function has been added. This feature allows the system to automatically power on after a power outage, which is particularly useful for servers or systems that need to maintain continuous operation.
5. ACC Core-Enhancer Function Improvement: The update addresses an issue where the HT (HyperTransport) link frequency needed to be decreased when using the ACC (Advanced Clock Calibration) core-enhancer function. This allows for more stable and optimized use of the ACC feature, which can potentially unlock hidden CPU cores.

Updating the BIOS: A Step-by-Step Guide

Disclaimer: Updating the BIOS is a potentially risky procedure. Proceed with caution and only if you are comfortable with the process. Ensure you have a stable power supply to prevent interruptions during the update.

1. Identify Your Current BIOS Version: Before you begin, it’s important to know your current BIOS version. You can usually find this information in the BIOS setup utility or by using a system information tool within your operating system.

2. Download the Correct BIOS File: Download the JetWay BA-500PRO1 Bios A03_W BIOS file from a reliable source. Ensure the file is specifically designed for your motherboard model (BA-500PRO1).

3. Prepare a Bootable USB Drive: You will need a bootable USB drive to flash the BIOS. There are several tools available to create a bootable USB drive, such as Rufus or the Windows Media Creation Tool. Format the USB drive as FAT32.
4. Copy the BIOS File and Flash Utility: Copy the downloaded BIOS file and the appropriate flash utility (AWDFLASH or AMIFLASH) to the bootable USB drive.
5. 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 the USB drive. Save the changes and exit the BIOS setup.
6. Run the Flash Utility: The system should now boot from the USB drive. At the command prompt, navigate to the directory containing the BIOS file and flash utility.

7. Execute the Flash Command: Execute the flash utility with the correct command line parameters as mentioned in the JetWay notice. For example:

   • AWDFLASH: AWDFLASH BIOS_FILENAME /cd/cp/ch/wb/qi
   • AMIFLASH: AMIFLASH BIOS_FILENAME /p /b/n /c /k

   Replace BIOS_FILENAME with the actual name of the BIOS file.

8. Wait for the Process to Complete: The flash utility will now update the BIOS. Do not interrupt the process. This may take a few minutes.
9. Restart Your Computer: Once the flashing process is complete, the utility will usually prompt you to restart your computer.
10. Load Optimized Defaults/Clear CMOS: After the restart, enter the BIOS setup utility and load optimized defaults or clear the CMOS as indicated in the JetWay notice. Save the changes and exit.
