Published in BIOS Update 3 mins read

Updating your BIOS using a .rom file typically involves creating bootable media, accessing the BIOS utility, and selecting the update file.

Here's a general process for updating your BIOS using a .rom file, based on common methods and the provided reference:

Steps to Update BIOS Using a .rom File

Updating your BIOS requires careful steps to avoid potential issues. The most common method using a .rom file involves a bootable USB drive and the built-in BIOS update utility.

1. Prepare the Update File

  • First, you need to download the correct BIOS .rom file for your specific motherboard model from the manufacturer's official website.
  • Ensure the file is compatible with your motherboard's revision number. An incorrect file can cause serious problems.

2. Create Bootable Media (Often a USB Drive)

  • Format a USB flash drive. It's often recommended to use FAT32 format.
  • Copy the downloaded .rom file onto the root directory of the USB drive. Do not place it in subfolders unless specifically instructed by your motherboard manufacturer.

3. Access the BIOS Utility

  • Insert the USB drive into a USB port on your computer.
  • Restart or turn on your computer.
  • During the initial boot sequence (often when the manufacturer's logo appears), press the key specified to enter the BIOS setup. Common keys include Del, F2, F10, or F12. Check your motherboard manual or screen prompts for the correct key.

4. Use the BIOS Update Utility

  • Once inside the BIOS interface, navigate to the built-in update utility. This utility is often referred to as EZ Flash (as mentioned in the reference), Q-Flash, M-Flash, or similar depending on the motherboard manufacturer (e.g., Asus, Gigabyte, MSI).
  • Go into the BIOS and use the EZ flash utility. Select this utility from the BIOS menu.

5. Select the ROM File

  • Inside the flash utility, you will typically be prompted to select the source of the update file.
  • Select the USB drive, which contains the .rom file.
  • Browse the contents of the USB drive and then select the .rom file located inside it. Ensure you select the correct file.

6. Initiate and Complete the Update

  • Confirm that you want to proceed with the BIOS update.
  • The utility will read the .rom file and begin flashing the new BIOS version.
  • From there the BIOS should update.
  • IMPORTANT: Do not interrupt the process (e.g., by turning off the computer) while the BIOS is being updated. This can permanently damage your motherboard.
  • Once the update is complete, the system will usually prompt you to restart.

7. Post-Update Steps

  • After restarting, the system will now be running the new BIOS version.
  • It is often recommended to enter the BIOS setup again to load default settings, save changes, and exit.

This process allows you to update your motherboard's firmware using a specific .rom file, utilizing the utility provided within the BIOS itself.
