When using the Ultra Fast boot setting of the Fast Boot option, the only way to get into the UEFI/BIOS without clearing it is to use the ASRock Restart to UEFI program.

But since that program is based on a Windows feature, and you aren't using Windows, the only way to get into the UEFI is to clear the UEFI/CMOS, sorry to say.

You can save all your UEFI/BIOS settings by saving them in a profile, with the option to do that in the OC Tweaker screen. You can then restore them with a few clicks by selecting the saved profile.

The Ultra Fast Boot option actually shortens POST time, so the overall startup or "boot time" is reduced. The help text for the Fast Boot option explains that using the Ultra Fast setting will require you to either use the Restart to UEFI program, or clear the UEFI/CMOS to get into the UEFI UI.

I know this is an old thread and chances are, you will not see this post. But, for those who do, this command worked great and got me right into the Asrock UEFI Bios, whether I was using Ultra Fast Boot or not.

Thanks.
