Brand new z6970 extreme for i9
I set bios to ultra fast boot and then couldn?�t get back into bios
Used clear cmos jumper
Went back into bios ans I see my drives but not options under boot section?
How do I get options for which jar drive to boot from?

Hi Jmeleshenko,

Thank you for your post.

Please try to enable the CSM under BIOS.

You can find it under BIOS\boot\CSM.

By the way, when the ultra-fast boot is enabled, it is not able to boot into BIOS at the booting stage. Please you out "Return to UEFI" to access BIOS.
