I am using an ASUS B85M-E motherboard for FREENAS 9.3. I need to set the motherboard to boot from the USB memory stick rather than the DVD or hard disk. I can do this manually during system startup with the F8 key but the USB boot does not show as an option when I try to set boot priority. So when I get a power failure the server tries to boot from my data disk which has no operating system and halts. Anyone know how to set this motherboard to automatically boot from a USB stick?
