This article provides information regarding the JetWay BA-500PRO1 motherboard BIOS update, specifically version A04_W. This update addresses several key issues and introduces a new functionality, improving the overall stability and usability of systems utilizing this motherboard. It is crucial to understand the purpose of BIOS updates and to follow the outlined instructions carefully to ensure a successful and safe update process.
Understanding the BIOS
The Basic Input/Output System (BIOS) is a fundamental piece of software embedded on a computer’s motherboard. It acts as the intermediary between the operating system and the hardware components. The BIOS performs several critical functions upon system startup, including:
- Power-On Self-Test (POST): A diagnostic test that verifies the functionality of essential hardware components like the CPU, memory, and storage devices.
- Boot Process Initiation: Locating and loading the operating system from a designated boot device.
- Hardware Configuration: Providing basic settings and configurations for hardware devices connected to the motherboard.
BIOS updates are released by motherboard manufacturers to address bugs, improve performance, enhance compatibility with newer hardware, and introduce new features. Applying these updates can significantly improve the user experience and extend the lifespan of a system.
Purpose of the JetWay BA-500PRO1 BIOS A04_W Update
The JetWay BA-500PRO1 BIOS A04_W update specifically targets the following issues and introduces the following enhancement:
-
Memory Capacity Display Issue in Windows 7: This update resolves a problem where Windows 7 systems incorrectly display the installed memory capacity as 4GB, even when the actual installed memory is greater than 4GB. This issue can prevent the system from fully utilizing the available RAM, leading to performance bottlenecks. By addressing this, the update ensures that Windows 7 correctly recognizes and utilizes all available memory. This is critical for users running memory-intensive applications like video editing software, games, or virtual machines.
-
PS/2 Keyboard and Mouse Swap Functionality: The A04_W BIOS update introduces a new feature that allows users to swap the functionality of the PS/2 keyboard and mouse ports. This feature provides flexibility in connecting and configuring PS/2 devices, especially in scenarios where port assignments are critical. This is particularly useful for legacy systems or users with specific hardware requirements. This functionality can be configured within the BIOS setup menu.
-
System Hang Issue with Full Screen Logo: This update addresses a bug that caused the system to hang after POST code ’78h’ when the full-screen logo function was enabled. This issue prevented the system from booting properly and required a system reset. The update resolves this stability issue, ensuring a smooth and reliable boot process even with the full-screen logo enabled. The JetWay BA-500PRO1 BIOS A04_W version ensures that the full screen logo function doesn’t cause system hang.
Updating the JetWay BA-500PRO1 BIOS: A Step-by-Step Guide
Important Note: Updating the BIOS is a critical process. Incorrectly flashing the BIOS can render your motherboard unusable. Proceed with caution and ensure you have a stable power supply throughout the entire process. It is highly recommended to back up your current BIOS settings before proceeding.
Procedure:
-
Download the BIOS Update: Download the Windows version of the JetWay BA-500PRO1 BIOS A04_W from a trusted source.
- Primary Download Link: https://www.techspot.com/drivers/driver/file/information/15008/
-
Extract the Downloaded File: The downloaded file will likely be a compressed archive (e.g., ZIP file). Use a suitable archive utility (such as WinRAR, 7-Zip, or the built-in Windows extraction tool) to extract the contents of the file to a dedicated folder on your hard drive.
-
Run the Executable File: Within the extracted folder, you will find an executable file (EXE). Double-click this file to launch the BIOS update utility.
-
Follow On-Screen Instructions: The BIOS update utility will guide you through the update process. Read each instruction carefully and follow the prompts. The utility will typically perform the following steps:
- Backup Current BIOS (Optional but Recommended): Some utilities offer the option to back up the existing BIOS before proceeding. This allows you to revert to the previous BIOS version if something goes wrong during the update process.
- Verify BIOS Version: The utility will likely verify that the BIOS version you are about to install is indeed a newer version than the one currently installed on your motherboard.
- Flash the BIOS: The utility will then proceed to flash the new BIOS to the motherboard’s BIOS chip. Do not interrupt this process! Power outages or system crashes during the flashing process can permanently damage the motherboard.
- Verify BIOS Flash: After flashing, the utility will typically verify that the new BIOS has been successfully written to the BIOS chip.
- Reboot System: Finally, the utility will prompt you to reboot your system.
-
Post-Update Verification: After the system reboots, enter the BIOS setup utility (usually by pressing DEL, F2, or another key during startup – refer to your motherboard manual). Verify that the BIOS version displayed in the BIOS setup utility is now A04_W. You may also need to reconfigure any custom BIOS settings that were reset during the update process.
