M= ake sure that these settings are configured correctly. Also make sure you have secure boot disabled.

I found that in few motherboard = (ASrock X100 and above, motherboard with AMD processor and MSI PC) Option R= om is not loading. In this case, inbox driver is taking control of the devi= ce. I checked PCI trace and found Option Rom has read from Expansion Rom addre= ss but not started (Driver entry not called). I tried with updated BIOS also and found same behavior. Please help.
