6. Operating Instructions

6.1. First Boot

After all components are installed and connected, power on your system. The system should display the BIOS/UEFI splash screen. If no display appears, refer to the troubleshooting section.

6.2. BIOS/UEFI Setup

To enter the BIOS/UEFI setup utility, press the designated key (usually DEL or F2) during the boot process. Here you can configure system settings, boot order, and monitor hardware status. While the BIOS GUI may appear basic, it provides full functionality for CPU overclocking, RAM timings, and other essential settings. BIOS updates may introduce new features and improve compatibility, such as support for Ryzen 5000 series CPUs.

6.3. Driver Installation

After installing your operating system, install the necessary drivers for the motherboard chipset, audio, LAN, and any other integrated components. These drivers can typically be found on the GALAX official website or on the provided driver CD/DVD.
