The ASRock H55M motherboard, a popular choice for budget-conscious PC builders during the Intel Lynnfield and Clarkdale era, relies on its BIOS (Basic Input/Output System) for fundamental operations. The BIOS is the first piece of software that runs when a computer is powered on, responsible for initializing hardware components, performing a Power-On Self-Test (POST), and loading the operating system. This article provides an informative overview of the ASRock H55M BIOS version 2.20, its significance, and considerations for users who might be looking to update or understand their system’s firmware.
Understanding the Role of the BIOS
Before delving into the specifics of version 2.20, it’s crucial to understand the BIOS’s broader function. The BIOS acts as a bridge between the hardware and the operating system. It contains essential instructions for the CPU, memory, storage devices, and other peripherals.
Key functions of the BIOS include:
- Power-On Self-Test (POST): This diagnostic routine verifies the proper functioning of critical hardware components during startup.
- Hardware Initialization: The BIOS initializes and configures essential hardware devices, such as the CPU, RAM, and chipset.
- Boot Process: The BIOS locates and loads the operating system from a specified boot device (e.g., hard drive, SSD, USB drive).
- System Configuration: The BIOS provides a user interface (often accessed by pressing a specific key during startup, such as Delete, F2, or F12) to configure various system settings, including boot order, CPU settings, memory timings, and fan speeds.
- Providing Low-Level Hardware Access: The BIOS provides low-level routines that the operating system can use to interact with the hardware.

ASRock H55M BIOS 2.20: Key Features and Improvements
BIOS updates are released by motherboard manufacturers to address bugs, improve compatibility with new hardware, enhance performance, and add new features. While specific release notes for ASRock H55M BIOS 2.20 may not be readily available, it’s reasonable to infer potential improvements based on common BIOS update practices.
Possible improvements in BIOS 2.20 might include:
- Enhanced CPU Compatibility: Support for newer revisions of Intel Lynnfield or Clarkdale processors.
- Improved Memory Support: Better compatibility with various DDR3 memory modules, potentially enabling higher clock speeds or tighter timings.
- Bug Fixes: Resolution of known issues related to system stability, hardware detection, or power management.
- Performance Optimizations: Minor tweaks to improve overall system performance.
- Security Updates: Patches to address potential security vulnerabilities.
- Enhanced Hardware Support: Added support for specific hard drives, SSDs, or other peripherals.
Updating the BIOS: Considerations and Precautions
Updating the BIOS can be a risky process if not performed correctly. A failed BIOS update can render the motherboard unusable. Therefore, it’s essential to follow these precautions:
- Verify Compatibility: Ensure that the BIOS update is specifically designed for the ASRock H55M motherboard. Installing an incorrect BIOS version can cause irreparable damage.
- Read the Instructions: Carefully read and understand the instructions provided by ASRock for updating the BIOS.
- Use a Reliable Power Source: Ensure a stable power supply during the update process. A power outage or fluctuation can interrupt the process and corrupt the BIOS. Using a UPS (Uninterruptible Power Supply) is highly recommended.
- Avoid Interruptions: Do not interrupt the BIOS update process once it has started.
- Back Up the Existing BIOS: If possible, back up the current BIOS version before updating. This provides a fallback option in case the update fails. Some motherboards offer built-in BIOS backup features.
- Use the Recommended Update Method: ASRock typically provides several methods for updating the BIOS, such as using a USB drive or a Windows-based utility. Use the recommended method for the ASRock H55M.
