&& Boot Override Allows you to select a device to boot immediately. Press on the device you select and select Yes to confirm. Your system will restart automatically and boot from that device. && Save Profiles This function allows you to save the current BIOS settings to a profile. You can create up to 8 profiles and save as Setup Profile 1~ Setup Profile 8. Press to complete. Or you can select Select File in HDD/FDD/USB to save the profile to your storage device. && Load Profiles If your system becomes unstable and you have loaded the BIOS default settings, you can use this function to load the BIOS settings from a profile created before, without the hassles of reconfiguring the BIOS settings. First select the profile you wish to load and then press to complete. You can select Select File in HDD/FDD/USB to input the profile previously created from your storage device or load the profile automatically created by the BIOS, such as reverting the BIOS settings to the last settings that worked properly (last known good record).
