ASRock H77M Bios 1.20

The ASRock H77M is a Micro ATX motherboard designed for use with Intel’s second and third generation Core processors (Sandy Bridge and Ivy Bridge) using the LGA 1155 socket. A BIOS (Basic Input/Output System) is a crucial piece of firmware embedded on a motherboard that initializes hardware components during the boot process and provides a low-level interface for the operating system. Updating the BIOS can resolve compatibility issues, improve system stability, and unlock new features or performance enhancements. This article provides information about the ASRock H77M BIOS version 1.20, including how to update it safely.

Features (General BIOS Functions)

While the provided source doesn’t explicitly list the specific features added or changed in BIOS 1.20, a BIOS in general offers a range of features critical to the system’s operation. These generally include:

• Hardware Initialization: The BIOS is responsible for detecting and initializing essential hardware components like the CPU, RAM, hard drives, and graphics card during the power-on self-test (POST).
• Boot Sequence: It determines the order in which the system attempts to boot from different devices (e.g., hard drive, USB drive, optical drive).
• System Configuration: The BIOS allows users to configure various system settings, such as CPU clock speeds, memory timings, fan control, and boot options.
• Power Management: The BIOS can manage power consumption by enabling or disabling certain features and setting power states.
• Security Features: Some BIOS versions offer security features like boot passwords and TPM (Trusted Platform Module) support.
• Hardware Monitoring: Monitoring system temperatures, fan speeds, and voltages.
• ACPI (Advanced Configuration and Power Interface): Facilitates power management and system configuration at the OS level.

What’s New (BIOS 1.20 Specifics)

Unfortunately, the supplied information lacks details about the specific improvements or fixes included in the ASRock H77M BIOS version 1.20. Typically, BIOS updates address issues such as:

How to Update the BIOS

Warning: Updating the BIOS is a sensitive process. A power outage or incorrect procedure during the update can render your motherboard unusable. Follow the instructions carefully and at your own risk.

ASRock motherboards commonly use a utility called "Instant Flash" to simplify the BIOS update process. The following methods outline how to update the BIOS using Instant Flash:

Before you begin:

• Identify Your Motherboard Revision: Ensure you are downloading the correct BIOS version for your specific motherboard revision.
• Download the BIOS File: Download the ASRock H77M BIOS version 1.20 from a reputable source. A suggested download link is: https://www.techspot.com/drivers/driver/file/information/16075/. Always download from the manufacturer’s website if possible.
• Prepare a USB Drive: You’ll need a USB flash drive formatted with the FAT32 file system.
• Backup Your Current BIOS (If Possible): Some BIOS utilities allow you to create a backup of your existing BIOS. This can be a lifesaver if the update fails.

Method 1: Updating from within the BIOS Setup

1. Extract the BIOS File: Extract the downloaded BIOS file (usually a .zip or .rar archive) to the root directory of your USB flash drive. The BIOS file itself will likely have a .ROM or .BIN extension.
2. Enter the BIOS Setup: Restart your computer and press the designated key (usually Delete, F2, F10, or F12) during the boot process to enter the BIOS setup utility. The key to press is usually displayed briefly on the screen during startup.
3. Locate the Instant Flash Utility: Navigate through the BIOS menus to find the "Instant Flash" utility. The location of this utility may vary depending on the BIOS version, but it’s typically found in the "Tool" or "Utilities" section.
4. Select the USB Drive: Instant Flash should automatically detect your USB drive. If not, select it manually.
5. Select the BIOS File: Choose the BIOS file (.ROM or .BIN) from the USB drive.
6. Confirm the Update: The utility will ask you to confirm the update. Double-check that you’ve selected the correct file and proceed with caution.
7. Wait for the Update to Complete: The BIOS update process will begin. Do not interrupt the process, turn off the computer, or unplug the USB drive. This can take several minutes.
8. Restart the System: Once the update is complete, the system will automatically restart.

Method 2: Updating During Boot (Instant Flash Hotkey)

1. Prepare the USB Drive: As with Method 1, extract the BIOS file to the root directory of a FAT32-formatted USB flash drive.
2. Insert the USB Drive: Insert the USB drive into a USB port on your computer before you power it on.
3. Power On and Press the Instant Flash Hotkey: Power on your computer. During the POST (Power-On Self-Test) screen, press the Instant Flash hotkey. The hotkey is often displayed on the screen during boot, but it’s commonly F6.
4. Select the USB Drive and BIOS File: The Instant Flash utility will appear. Select your USB drive and then the BIOS file (.ROM or .BIN).
5. Confirm the Update: Verify that you’ve selected the correct BIOS file and confirm the update.
6. Wait for the Update to Complete: Allow the update process to finish without interruption.
7. Restart the System: The system will automatically restart after the update is complete.

Important Notices

• DO NOT Interrupt the Update: If you encounter problems while updating the new BIOS, DO NOT turn off your system. A corrupted BIOS can prevent your system from booting.
• Repeat the Process: If the update fails, repeat the process.
• Revert to the Original BIOS: If the problem persists, attempt to update to the original BIOS file that was previously installed.
• Seek Professional Help: If the Flash Memory Writer utility fails to update a complete BIOS file, your system may be unbootable. In this case, professional service is required.
• Power Stability: Ensure a stable power supply during the update process. A UPS (Uninterruptible Power Supply) is highly recommended.

Updating the ASRock H77M BIOS is a procedure that should be approached with care. The BIOS version 1.20 may contain critical updates for your system’s performance and stability. By following the instructions carefully, you can increase your chances of a successful update.
