Updating the BIOS (Basic Input/Output System) on your computer can be a crucial step to ensure compatibility with new hardware, improve system stability, and unlock new features. This article provides a comprehensive guide on how to update the ASRock N68-S BIOS to version 1.40 using a Windows-based utility. It’s important to understand that flashing your BIOS is a sensitive process, and incorrect execution can lead to system instability or even render your computer unusable. Therefore, it’s vital to follow the instructions carefully and proceed with caution.
Understanding the BIOS
The BIOS is a firmware program embedded on a small chip on your motherboard. It’s the first software that runs when you power on your computer, performing essential tasks such as:
- Power-On Self-Test (POST): Diagnosing hardware components to ensure they are functioning correctly.
- Bootstrapping: Locating and loading the operating system from a storage device (e.g., hard drive, SSD).
- Providing low-level hardware control: Enabling communication between the operating system and hardware components.
Updating your BIOS can address compatibility issues, fix bugs, and improve overall system performance. The ASRock N68-S BIOS update to version 1.40 specifically modifies the BIOS code for the Super I/O (Input/Output) controller. This controller manages communication with various peripherals like serial and parallel ports, keyboard, and mouse.
Preparing for the BIOS Update
Before proceeding with the update, ensure you have the following:
- A stable power supply: A power outage during the BIOS flashing process can corrupt the BIOS chip, rendering your system unbootable. It is recommended to use a UPS (Uninterruptible Power Supply) if available.
- The correct BIOS file: Download the BIOS 1.40 specifically designed for the ASRock N68-S motherboard. Using the wrong BIOS file can severely damage your system.
- A working Windows environment: This guide outlines the procedure for updating the BIOS from within Windows.
- Disable any Antivirus Software: Sometimes Antivirus software can interfere with the BIOS update process

Step-by-Step BIOS Update Procedure (Windows)
The following steps outline the process of updating the ASRock N68-S BIOS to version 1.40 within a Windows environment.
-
Download and Extract: Download the BIOS package (usually a WinZip format with a .zip file extension) from the provided link. After downloading, extract all files to a dedicated folder on your hard drive. Ensure you remember the location of this folder. You should find files like
AFUWIN.EXE,UCORESYS.SYS,UCOREVXD, andUCOREW64.SYSwithin the extracted folder. -
Close All Programs: Before proceeding, close all running applications. This minimizes the risk of conflicts during the BIOS flashing process.
-
Run AFUWIN.EXE as Administrator (Crucial Step): Locate the
AFUWIN.EXEfile in the extracted folder. Right-click on theAFUWIN.EXEfile and select "Run as administrator." This is crucial, especially in Windows Vista and later versions, as it grants the necessary permissions for the utility to access and modify the BIOS. -
Confirmation Dialog: A dialog box may appear, reminding you to close other programs. Click "OK" to proceed.
-
BIOS Update Process: The AFUWIN utility will now begin the BIOS update process. Do not interrupt this process. This may involve a progress bar or status messages. Be patient and allow the utility to complete the update.
-
Restart Confirmation: After the BIOS update is complete, a dialog box will appear, prompting you to restart your system. Click "Yes" to restart.
-
Enter BIOS Setup: As your system restarts, press the designated key (usually F2 or Delete) to enter the BIOS setup utility. The key to press is usually displayed on the screen during the initial boot sequence.
-
Load Default Settings: Once inside the BIOS setup utility, navigate to the "Exit" menu. Locate the "Load Default Settings" option and select it. Press the Enter key to confirm. This step is essential to ensure compatibility with the new BIOS version.
-
Save and Exit: After loading the default settings, select "Exit Saving Changes" from the "Exit" menu. Press Enter to confirm and exit the BIOS setup utility.
-
Boot with New BIOS: Your system will now boot up with the new BIOS version.
Checking the BIOS Version
You can verify the BIOS version in two ways:
-
During System Boot: The BIOS version is often displayed briefly on the screen during the initial boot sequence, before the operating system loads. Look for a line of text that indicates the BIOS version.
-
In BIOS Setup Utility: Enter the BIOS setup utility (as described in step 7 above). The BIOS version is typically displayed on the main screen or in the "System Information" section.
Important Notice and Troubleshooting
Critical Warning: If you encounter any problems during the BIOS update process, DO NOT turn off your system. An interrupted BIOS flash can corrupt the BIOS chip and prevent your system from booting.
Troubleshooting:
- Repeat the Process: If the update fails, try repeating the entire process from the beginning. Ensure you have a stable power supply and that all other programs are closed.
- Update with Original BIOS: If the problem persists, try updating with the original BIOS file (if you have a backup).
- Seek Professional Help: If the Flash Memory Writer utility is unable to successfully update the BIOS, and your system fails to boot, your system will likely require professional service. Contact a qualified computer technician or the motherboard manufacturer for assistance.
Updating the ASRock N68-S BIOS to version 1.40 can improve your system’s compatibility and stability. By carefully following these instructions, you can minimize the risk of complications and ensure a successful BIOS update. Remember to always exercise caution when flashing your BIOS, and seek professional help if you encounter any difficulties.
