AOpen MP55-D Bios R1.02

The AOpen MP55-D Bios R1.02 is a firmware update released for the AOpen MP55-D motherboard. This document provides a comprehensive overview of the BIOS update, including its enhancements, fixes, and instructions for installation. The information is based on the official release notes from AOpen, last updated on September 20, 2010. This article aims to provide a clear and informative guide for users considering updating their AOpen MP55-D motherboard BIOS to version R1.02.

Understanding BIOS and Its Importance

Before delving into the specifics of the AOpen MP55-D Bios R1.02, it’s crucial to understand the fundamental role of a BIOS (Basic Input/Output System). The BIOS is a firmware embedded on a small chip on the motherboard. It’s the first software that runs when a computer is powered on. Its primary functions include:

• Power-On Self-Test (POST): Diagnosing and initializing system hardware components like the CPU, memory, and peripherals.
• Bootstrapping the Operating System: Locating and loading the operating system from a storage device (e.g., hard drive, SSD).
• Providing Low-Level Hardware Control: Offering a set of routines that the operating system can use to interact with hardware.

Updating the BIOS can resolve compatibility issues, improve system performance, and enable support for new hardware. However, it’s a process that should be approached with caution, as an interrupted or incorrectly executed update can render the motherboard unusable.

What’s New in AOpen MP55-D Bios R1.02

The AOpen MP55-D Bios R1.02 update brings several key improvements and fixes to the motherboard. The following list details the changes implemented in this version:

1. Intel P4500 Processor Support: The most significant update is the added support for Intel P4500 series processors. This allows users to upgrade their CPU to a compatible P4500 model, potentially improving system performance.

2. RTC Wake Settings Submenu Renaming: The submenu labeled "S5 RTC Wake Settings" has been renamed to "RTC Wakeup from S5 Settings." This change is purely cosmetic and aims to provide a clearer description of the submenu’s function.

3. BIOS Item Renaming: Similarly, the BIOS item "Wake system with Fixed Time" has been renamed to "RTC Wakeup from S5." This renaming aligns with the submenu change, providing a more consistent and understandable naming convention for the RTC wake-up functionality.

4. RTC Function Item Support: The update introduces support for RTC (Real-Time Clock) function items. This likely refers to expanded options and control over the system’s real-time clock, potentially allowing for more precise scheduling and wake-up configurations.

5. 64-bit OS Installation Fix: A critical bug that prevented the installation of 64-bit operating systems when 8GB of memory was installed has been resolved. This fix is essential for users who want to utilize the full potential of their 8GB RAM configurations with a 64-bit OS.

6. C3 and C6 State Usage Fix: The update addresses an issue where the system couldn’t accurately track the usage of C3 and C6 power-saving states. Correctly monitoring these states is crucial for optimizing power consumption and extending battery life in mobile systems (if applicable).

7. SLP Function Support: The AOpen MP55-D Bios R1.02 adds support for the SLP (Software Licensing Protection) function. SLP is a technology used to activate Windows operating systems and other software. This update likely improves the compatibility and reliability of SLP activation.

Updating the AOpen MP55-D Bios R1.02

The release notes provide specific instructions for updating the BIOS, outlining two methods: one for DOS and another for Windows. It is crucial to follow these instructions precisely to avoid potential damage to your motherboard.

Important Considerations Before Updating:

• Backup Your Existing BIOS: If possible, back up your current BIOS version before proceeding with the update. This provides a fallback option in case the new BIOS causes issues.
• Ensure a Stable Power Supply: Interruptions during the BIOS update process can be catastrophic. Ensure your computer is connected to a stable power source, preferably a UPS (Uninterruptible Power Supply).
• Close All Running Applications: Close all unnecessary applications before starting the update process.

DOS Update Method:

1. Download the AOpen MP55-D Bios R1.02 update package. You can download the driver here: https://www.techspot.com/drivers/driver/file/information/14451/

2. Extract the contents of the package to a bootable DOS USB drive or floppy disk.

3. Boot your computer from the DOS USB drive or floppy disk.

4. At the DOS prompt, run the following command:

   AFUDOS IMB18.ROM /P /B /N /Reboot

   • AFUDOS is the BIOS flashing utility.
   • IMB18.ROM is the BIOS image file.
   • /P programs the main BIOS.
   • /B programs the boot block.
   • /N programs the NVRAM.
   • /Reboot automatically reboots the system after the update.

5. Wait for the update process to complete. The system will automatically reboot.

Windows Update Method:

1. Download the AOpen MP55-D Bios R1.02 update package.

2. Extract the contents of the package to a folder on your hard drive.

3. Run the winflash.bat batch file. This file should contain the following command:

   AFUWIN IMB18.ROM /P /B /N /Reboot

   • AFUWIN is the Windows BIOS flashing utility.
   • IMB18.ROM is the BIOS image file.
   • /P programs the main BIOS.
   • /B programs the boot block.
   • /N programs the NVRAM.
   • /Reboot automatically reboots the system after the update.

4. Follow the on-screen prompts to complete the update. The system will automatically reboot.

Post-Update Verification:

After the update, it’s essential to verify that the new BIOS version is correctly installed. You can do this by entering the BIOS setup utility (usually by pressing DEL, F2, or another key during startup) and checking the BIOS version displayed.
