The Asus P7H55-M/BR motherboard, a reliable and feature-rich option for its time, utilized the Intel H55 Express chipset and supported the first generation of Intel Core i3, Core i5, and Core i7 processors (LGA 1156 socket). A crucial aspect of maintaining optimal performance and compatibility for this motherboard is ensuring the BIOS is up-to-date. This article provides an overview of BIOS version 0405 for the Asus P7H55-M/BR, its potential benefits, and how to obtain and install it.
Understanding the BIOS and Its Importance
The Basic Input/Output System (BIOS) is a fundamental piece of software embedded on a motherboard. It’s the first code that runs when a computer is powered on, performing essential tasks like:
- Hardware Initialization: The BIOS tests and initializes crucial hardware components like the CPU, memory, chipset, and storage devices.
- Boot Process: It locates and loads the operating system from a designated boot device (e.g., hard drive, SSD).
- Hardware Configuration: The BIOS allows users to configure various hardware settings, such as boot order, memory timings, and fan speeds.
- Firmware Updates: It provides a mechanism to update the BIOS itself, incorporating bug fixes, performance enhancements, and support for new hardware.
Updating the BIOS is often recommended to address compatibility issues with newer hardware, resolve known bugs, improve system stability, and enhance overall performance.

Flashing the Asus P7H55-M/BR Bios 0405: A Step-by-Step Guide
Flashing the BIOS is a delicate process, and it’s essential to follow the instructions carefully to avoid damaging your motherboard. Here’s a general guide, but always refer to the specific instructions provided by ASUS for the Asus P7H55-M/BR.
Preparation:
- Download the BIOS File: Download the BIOS 0405 file from a reputable source, such as the TechSpot link provided above.
- Prepare a USB Drive: You’ll need a USB drive formatted with FAT32.
- Extract the BIOS File: Extract the contents of the downloaded ZIP file to the USB drive. The extracted file will typically have a ".ROM" or ".CAP" extension.
- Back Up Your Current BIOS (if possible): Some BIOS utilities allow you to back up your current BIOS before flashing a new one. This is a good precaution in case something goes wrong.
Flashing Process:
- Enter the BIOS Setup: Restart your computer and press the appropriate key to enter the BIOS setup utility. This key is usually displayed during the boot process (e.g., Delete, F2, F12).
- Locate the BIOS Flashing Utility: The BIOS setup utility will have a section for flashing the BIOS. The name of the utility may vary depending on the BIOS version, but it’s often called "EZ Flash," "Q-Flash," or something similar.
- Select the BIOS File: Use the BIOS flashing utility to select the BIOS file (.ROM or .CAP) from the USB drive.
- Confirm the Flash: The utility will likely ask you to confirm that you want to flash the BIOS. Double-check that you’ve selected the correct file and proceed with caution.
- Wait for the Flashing Process to Complete: The flashing process can take several minutes. Do not interrupt the process by turning off the computer or removing the USB drive.
- Restart the Computer: Once the flashing process is complete, the computer will automatically restart.
- Enter the BIOS Setup Again: After the restart, enter the BIOS setup utility again and load the default settings. This will ensure that the BIOS is configured correctly with the new version.
Important Warnings:
- Power Interruption: Do not interrupt the power supply during the BIOS flashing process. A power outage or sudden shutdown can corrupt the BIOS and render your motherboard unusable.
