The BIOS is vital to overclocking, and is where you can alter many of your system's settings. Gigabyte uses a Dual BIOS technology, which basically means that if one of your BIOS is shot or doesn't boot up, the motherboard will load up the second BIOS. This provides great peace of mind while you're overclocking, because you know that if you mess up the BIOS, there's a second one that will load up.
Main & Standard CMOS:
When you first boot up, you'll be shown the Main screen, which is where you can pick and choose what you want to alter from multiple sections. The "Standard CMOS Setup" is where you can check on the drives you have hooked up, and you can also change the time and date.
Advanced BIOS Features:
Here you can alter the CPU functions, such as CPUID, C1E, EIST, and Virtualization, as well as your boot device order.
Integrated Peripherals & Power Management:
Under "Integrated Peripherals", you can change the onboard LAN and SATA settings. The Power Management tab is where you can set up your power features.
PnP/PCI & PC Health Status:
Under these tabs, you can decide which display initializes for graphics first, and view the fan speeds and temperatures of your system.
