• Boot order for storage devices.
• System date and time.
• CPU and memory settings.
• Peripheral configurations.

5.3 Operating System Installation

Once BIOS settings are configured, you can proceed with installing your preferred operating system (e.g., Windows, Linux) from a bootable USB drive or DVD. Follow the on-screen instructions provided by your operating system installer.

5.4 Driver Installation

After installing the operating system, install the necessary drivers for the motherboard components. These typically include chipset drivers, network drivers (RTL8111H Gigabit Network), audio drivers (ALC897 7.1 Channel), and any other peripheral drivers. Drivers are usually provided on a CD/DVD with the motherboard or can be downloaded from the manufacturer's website.

6. Maintenance
