Check BIOS Flash Support

TL;DR

This guide helps you determine if your computer’s BIOS can be updated (flashed). We’ll cover checking manufacturer websites, using system information tools, and looking in the BIOS setup itself.

1. Identify Your Motherboard

Before you start, you need to know exactly which motherboard you have. This is crucial for downloading the correct BIOS file.

• Physically inspect: Open your computer case (unplug it first!) and look for markings on the motherboard itself. The manufacturer’s name and model number are usually printed clearly.
• System Information (Windows): Press Win + R, type msinfo32 and press Enter. Look for ‘BaseBoard Manufacturer’ and ‘BaseBoard Product’.
• Linux Terminal: Open a terminal and run the command

  sudo dmidecode -t baseboard

  . This will display motherboard information.

2. Check the Manufacturer’s Website

The manufacturer’s website is the best place to find BIOS updates and compatibility information.

• Navigate to Support: Go to the support section of your motherboard manufacturer’s website (e.g., ASUS, Gigabyte, MSI, ASRock).
• Search for Your Model: Enter your exact motherboard model number in the search bar.
• Look for BIOS Updates: If updates are available, it confirms that flashing is possible. Download the latest version (and read the instructions carefully!).

3. Using System Information Tools

Some tools can detect if a BIOS update is recommended.

• Manufacturer’s Utility: Many manufacturers provide dedicated utilities that check for driver and BIOS updates (e.g., ASUS Live Update, Gigabyte EasyTune).
• Third-Party Tools: Be cautious with third-party tools; stick to reputable sources. Some can identify outdated BIOS versions but always verify the information on the manufacturer’s website before flashing.

4. Check Within the BIOS Setup

Some BIOS setups have built-in features for updating.

• Enter BIOS: Restart your computer and press the appropriate key during startup (usually Del, F2, F12, or Esc – check your motherboard manual).
• Look for Update Tools: Navigate through the BIOS menus. Look for options like ‘BIOS Flash’, ‘EZ Flash’, ‘Q-Flash’, or similar terms. If you find these, it means your BIOS supports flashing.

5. Important Considerations

• Power Supply: Ensure a stable power supply during the flash process. A power outage can brick your motherboard. Consider using an uninterruptible power supply (UPS).
• Read Instructions Carefully: Always follow the manufacturer’s instructions precisely. Incorrect flashing can render your motherboard unusable.
• Backup Your BIOS: If possible, back up your current BIOS before updating. Some motherboards allow this feature within the BIOS setup.
