How do I enter the BIOS setup on the PRIME H610M-A D4?

Press the Delete or F2 key during the Power-On Self Test (POST) to enter BIOS Setup at startup. If you miss the POST window, you can also press Ctrl+Alt+Delete simultaneously, press the reset button on the chassis, or power the system off and back on, then press Delete. The BIOS supports both EZ Mode and Advanced Mode, switchable via the F7 hotkey. (Page 2-2)
