Intel Z790/H770/B760 Series Chapter 3 UEFI SETUP UTILITY 3.1 Introduction ASRock UEFI (Unified Extensible Firmware Interface) is a BIOS utility which offers tweakfriendly options in an advanced viewing interface. The UEFI system works with a USB mouse and offers users a faster, sleeker experience. This BIOS utility can perform the Power-On Self-Test (POST) during system startup, record hardware parameters of the system, load operating system, and so on. The battery on the motherboard supplies the power needed to the CMOS when the system power is turned off, and the values configured in the UEFI utility are kept in the CMOS. Please note that inadequate BIOS settings may cause system instability, mulfunction or boot failure. We strongly recommend that you do not alter the UEFI default configurations or change the settings only with the assistance of a trained service person. If the system becomes unstable or fails to boot after you change the setting, try to clear the CMOS values and reset the board to default values. See your motherboard manual for instructions. 3.1.1 Entering BIOS Setup You may run the UEFI SETUP UTILITY by pressing or right after you power on the computer; otherwise, the Power-On-Self-Test (POST) will continue with its test routines. If you wish to enter the UEFI SETUP UTILITY after POST, restart the system by pressing + + , or by pressing the reset button on the system chassis. You may also restart by turning the system off and then back on. This setup guide explains how to use the UEFI SETUP UTILITY to configure all the supported system. The screenshots in this manual are for reference only. UEFI Settings and options may vary owing to different BIOS release versions or CPU installed. Please refer to the actual BIOS version of the motherboard you purchased for detailed screens, settings and options. 25
