Connect the brick AC adapter. The brick has a green power LED, I suppose some other bricks do, but I’ve never seen one.
The Asus AT3IONT-I Deluxe uses the American Megatrends BIOS, like nearly all other Asus motherboards. The AMI BIOS is a tabbed BIOS for easy navigation. The Main menu has date/time, drives found during POST, and a couple of submenus, including system information.
The System Information submenu has the BIOS version and the most basic CPU information.
The Advanced menu contains several submenus that contain most system settings.
The CPU Configuration submenu has more detailed information about the processor and a few CPU settings.
The Jumperfree submenu contains overclocking relevant settings. Overclocking on this board is very basic.
The Onboard Devices submenu contains settings for various board features.
The Power menu contains a few power related settings and a couple of submenus, including the hardware monitor.
The Hardware Monitor submenu has temps and voltages. If you’ll notice, the CPU temperature is 63C. That is with the CPU at idle for three or so hours. Though that is higher than I particularly like, I’ll monitor it while at load before making my determination on some cooling.
The Boot menu has a couple of submenus including the Boot Settings Configuration. There you can disable the POST splash screen if desired.
