ASRock 4CoreDual-SATA2 R2.0 Bios 1.90 for DOS

This article provides information about the ASRock 4CoreDual-SATA2 R2.0 BIOS version 1.90, specifically designed for updating the motherboard’s firmware through a DOS environment. It will cover the purpose of a BIOS update, the specifics of this particular update, the procedure for flashing the BIOS using DOS, potential risks and considerations, and alternative download locations for the BIOS file.

Understanding the BIOS and its Importance

The Basic Input/Output System (BIOS) is a crucial piece of firmware embedded on a computer’s motherboard. It acts as the intermediary between the operating system and the hardware components of the system. Upon powering on the computer, the BIOS performs a self-test (POST – Power-On Self-Test) to verify the functionality of essential hardware like the CPU, memory, and storage devices. It then initializes these components and loads the operating system.

The BIOS also provides a low-level interface for configuring hardware settings, such as boot order, CPU clock speeds, memory timings, and fan control. These settings are typically accessed through a BIOS setup utility, which can be entered during the boot process by pressing a specific key (often Delete, F2, F12, or Esc, depending on the motherboard manufacturer).

Why Update the BIOS?

Updating the BIOS is a process that replaces the existing firmware with a newer version. This is often done to:

• Improve Hardware Compatibility: New hardware, such as CPUs, memory modules, or graphics cards, may require updated BIOS firmware to function correctly with the motherboard. BIOS updates can include the necessary drivers and settings to support these new components.
• Fix Bugs and Errors: BIOS updates can address bugs and errors in the existing firmware that may cause system instability, performance issues, or compatibility problems.
• Enhance System Performance: Some BIOS updates may include optimizations that improve overall system performance, such as faster boot times or improved CPU and memory management.
• Add New Features: Occasionally, BIOS updates may introduce new features, such as support for new storage technologies or enhanced security options.
• Address Security Vulnerabilities: Like any software, BIOS firmware can contain security vulnerabilities. BIOS updates can patch these vulnerabilities, protecting the system from potential exploits.

Flashing the BIOS via DOS: A Step-by-Step Guide

Flashing the BIOS is a sensitive process that, if not performed correctly, can render the motherboard unusable. Therefore, it’s essential to follow the instructions carefully and take precautions to minimize the risk of errors. This section outlines the general steps involved in flashing the BIOS using DOS.

Disclaimer: Proceed with caution. Incorrectly flashing the BIOS can brick your motherboard, rendering it unusable. Ensure you have the correct BIOS file for your specific motherboard model (ASRock 4CoreDual-SATA2 R2.0) and revision. Back up your existing BIOS if possible.

1. Preparation:

• Download the BIOS file: Obtain the ASRock 4CoreDual-SATA2 R2.0 Bios 1.90 from a reputable source. A download link is provided here: https://www.techspot.com/drivers/driver/file/information/10102/
• Prepare a bootable DOS USB drive: You’ll need a USB drive formatted as bootable DOS. Several tools can create bootable DOS drives, such as Rufus or the HP USB Disk Storage Format Tool.
• Copy the BIOS file and flashing utility to the USB drive: Extract the contents of the downloaded BIOS archive (usually a .zip file) to the root of the bootable DOS USB drive. This should include the BIOS file itself (usually a .bin or .rom file) and the flashing utility (often named something like "AWDFLASH.EXE" or "AMIFLASH.EXE").

2. Booting into DOS:

• Insert the USB drive into the target computer.
• Power on the computer and enter the BIOS setup utility. This is usually done by pressing Delete, F2, F12, or Esc during the boot process.
• Configure the boot order to prioritize the USB drive. This will ensure that the computer boots from the USB drive instead of the hard drive.
• Save the changes and exit the BIOS setup utility. The computer should now boot into the DOS environment from the USB drive.

3. Flashing the BIOS:

• At the DOS prompt, navigate to the USB drive. This is typically done by typing the drive letter (e.g., "C:" or "D:") followed by a colon and pressing Enter.
• 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., "4CDSR20.190"). You may need to consult the documentation provided with the BIOS file for the correct command-line parameters.
• Follow the on-screen instructions. The flashing utility will guide you through the process. Be patient and do not interrupt the process.
• Verify the flash. After the flashing process is complete, the utility may prompt you to verify the flash. Follow the instructions to ensure that the BIOS has been updated correctly.

4. Reboot and Verify:

• Remove the USB drive.
• Reboot the computer.
• Enter the BIOS setup utility again.
• Verify that the BIOS version has been updated to 1.90.
• Load default settings. After flashing, it’s often recommended to load the default BIOS settings to ensure optimal stability.
• Save the changes and exit the BIOS setup utility.

Potential Risks and Considerations:

• Incorrect BIOS file: Using the wrong BIOS file can brick the motherboard. Ensure you have the correct file for the ASRock 4CoreDual-SATA2 R2.0.
• Power failure: A power outage during the flashing process can corrupt the BIOS and render the motherboard unusable. It’s recommended to use a UPS (Uninterruptible Power Supply) to protect against power failures.
• Interrupted flashing process: Interrupting the flashing process for any reason can corrupt the BIOS. Do not restart or shut down the computer during the flashing process.
• Compatibility issues: While a BIOS update is intended to improve compatibility, it can sometimes introduce new issues. It’s a good idea to research whether other users have reported any problems with the specific BIOS version before flashing.
• CMOS battery: A weak or dead CMOS battery can sometimes interfere with the BIOS flashing process. Consider replacing the CMOS battery before flashing the BIOS.
