ASRock P45XE-R Bios 1.20 for DOS

This article provides information regarding the ASRock P45XE-R motherboard and its BIOS update, specifically version 1.20 designed for DOS-based flashing. It details the purpose of a BIOS update, the potential benefits of updating to this specific version, and instructions for safely flashing the BIOS using the DOS environment. Understanding the risks involved and following the correct procedures are crucial for a successful update.

Understanding the BIOS and its Importance

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 the computer is powered on, responsible for initializing hardware components and loading the operating system. Think of it as the conductor of an orchestra, ensuring all the instruments (hardware) are ready to play in harmony.

The BIOS contains crucial settings that control various aspects of the motherboard’s functionality, including:

• Boot Order: Determines the sequence in which the computer attempts to boot from different devices (hard drives, USB drives, optical drives).
• Hardware Detection: Identifies and configures installed hardware components like the CPU, RAM, and storage devices.
• Power Management: Controls power-saving features and voltage settings.
• Overclocking Settings: Allows users to adjust CPU and memory speeds beyond their default specifications (use with caution!).

A outdated BIOS can sometimes lead to compatibility issues with newer hardware, performance bottlenecks, or even system instability.

ASRock P45XE-R and BIOS Updates

The ASRock P45XE-R is a motherboard based on the Intel P45 chipset, a popular choice for enthusiasts and gamers in its time. Like all motherboards, the ASRock P45XE-R relies on its BIOS to function correctly. ASRock, the manufacturer, releases BIOS updates periodically to address bugs, improve compatibility, and enhance performance.

Updating the BIOS to version 1.20 for the ASRock P45XE-R could offer several advantages:

• Improved Hardware Compatibility: Support for newer CPUs, RAM modules, or other peripherals that weren’t fully compatible with earlier BIOS versions.
• Bug Fixes: Resolution of known issues or stability problems that might be present in previous BIOS versions.
• Performance Enhancements: Potentially optimized performance for existing hardware configurations.
• Security Patches: Addresses any known security vulnerabilities in the BIOS.

Disclaimer: It’s important to note that BIOS updates are not always necessary. If your system is functioning correctly and you’re not experiencing any issues, there might not be a compelling reason to update.

Preparing for the BIOS Update

Before proceeding with the BIOS update, it’s essential to take the following precautions:

1. Identify Your Motherboard: Double-check that you indeed have the ASRock P45XE-R motherboard. Incorrect BIOS versions can cause serious damage.
2. Download the Correct BIOS File: Obtain the BIOS 1.20 file specifically designed for the ASRock P45XE-R. Using the wrong file can brick your motherboard, rendering it unusable. The official download link is: https://www.techspot.com/drivers/driver/file/information/10843/
3. Alternative Download Link: AsRock support : https://download.asrock.com/bios/775/P45XE-R(1.20)DOS.zip, Softpedia : https://drivers.softpedia.com/get/BIOS/AsRock/ASRock-P45XE-R-BIOS-1-20.shtml, DriverGuide : https://www.driverguide.com/driver/detail.php?driverid=1652278, ComputerBase : https://www.computerbase.de/downloads/treiber/mainboards/asrock/asrock-p45xe-r/, AllDriver : https://www.alldriver.com/driver/mainboard/asrock/P45XE-R_11216.html
4. Prepare a Bootable DOS USB Drive: You’ll need a USB drive formatted as bootable DOS. Several tools are available online to create a bootable DOS USB drive, such as Rufus or HP USB Disk Storage Format Tool.
5. Copy the BIOS File and Flashing Utility: After creating the bootable DOS USB drive, copy the downloaded BIOS file (usually a .ROM or .BIN file) and the ASRock flashing utility (usually named AWDFLASH.EXE or similar) to the USB drive. These utilities are often included in the downloaded BIOS archive.
6. Backup Your Current BIOS (Optional but Recommended): Some flashing utilities allow you to back up your existing BIOS before updating. This is highly recommended as a safety net in case the update fails.
7. Ensure a Stable Power Supply: A power outage during the BIOS update process can corrupt the BIOS and render the motherboard unusable. Use a UPS (Uninterruptible Power Supply) if possible, or ensure a stable power source.
8. Disconnect Unnecessary Peripherals: Disconnect any non-essential USB devices or peripherals to minimize the risk of conflicts during the update process.

Flashing the BIOS in DOS

Warning: Flashing the BIOS is a risky procedure. Incorrectly flashing the BIOS can brick your motherboard, rendering it unusable. Proceed at your own risk.

1. Boot from the USB Drive: Restart your computer and enter the BIOS setup menu (usually by pressing DEL, F2, or F12 during startup). Change the boot order to boot from the USB drive.

2. Navigate to the DOS Prompt: Once booted from the USB drive, you should be at a DOS prompt (usually A:>).

3. Run the Flashing Utility: Type the name of the flashing utility (e.g., AWDFLASH.EXE) followed by the name of the BIOS file (e.g., P45XER1.20). The exact command-line syntax will depend on the specific flashing utility. Refer to the ASRock documentation or the utility’s help screen for the correct syntax. An example command might be: AWDFLASH P45XER1.20 /py /sn /cc /cp /cd

   • /py: Program Flash ROM.
   • /sn: No Serial Number.
   • /cc: Clear CMOS.
   • /cp: Program the Boot Block
   • /cd: Clear DMI data

4. Confirm the Update: The flashing utility will likely ask you to confirm that you want to update the BIOS. Double-check that you have the correct BIOS file and that you understand the risks before proceeding.

5. Wait for the Update to Complete: The BIOS update process will take a few minutes. Do not interrupt the process by turning off the computer or unplugging the power.

6. Verify the Update: After the update is complete, the flashing utility will usually prompt you to restart the computer. After restarting, enter the BIOS setup menu and verify that the BIOS version has been updated to 1.20.

7. Load Default Settings (Recommended): After flashing the BIOS, it’s often recommended to load the default BIOS settings. This can help ensure stability and prevent any conflicts caused by settings from the previous BIOS version.

8. Reconfigure BIOS Settings (If Necessary): If you had any custom BIOS settings (e.g., overclocking settings), you’ll need to reconfigure them after loading the default settings.

Troubleshooting

If the BIOS update fails, you may encounter the following issues:

• Computer Won’t Boot: The computer may not power on or may power on but display nothing on the screen.
• BIOS Error Messages: The computer may display error messages related to the BIOS.

In such cases, you may need to attempt to recover the BIOS using a backup BIOS (if your motherboard has dual BIOS) or by using a BIOS recovery tool. Refer to the ASRock documentation for specific instructions on how to recover from a failed BIOS update. In the worst-case scenario, the motherboard might need to be replaced.

Conclusion

Updating the ASRock P45XE-R BIOS to version 1.20 can potentially improve compatibility, fix bugs, and enhance performance. However, it’s crucial to understand the risks involved and to follow the correct procedures carefully. By taking the necessary precautions and following the instructions outlined in this article, you can increase your chances of a successful BIOS update. Always remember to download the correct BIOS file for your specific motherboard model and to ensure a stable power supply during the update process.
