Intel Motherboards : X99 Extreme 6 BIOS

You are correct Putting part 1, 2 and 3 together makes no sense but what happens regardless of BIOS settings is the boot order gets changed so that ATA, which is the 941, tries to boot first. Linux or windows does not matter.  Nothing changes this as far as I have seen.

 

I had no choice but to upgrade the ME firmware when I installed the 3.20 bios.  When I went to the Intel website and downloaded and installed the latest IME and installed a WINDOWS driver.  So how does a driver in windows (upgrading the IME driver) effect the drive selection before windows is even started?  You got me on this if you can answer this question.

 

Second I must be running the Samsung driver if I can even access this device.

 

Thirdly I don't expect you to write the code to boot UEFI vs MBR but I do expect you, as an agent of Asrock, like the rest of the people on this forum expect you too, is to have some knowledge that can help me.  If you can't or you don't want to please tell me who to contact at Asrock.

 

Oh, I did try the CSM options like you said.  NOTHING DIFFERENT TO REPORT.  Sorry for not expressly  reporting nothing to report.

 

I have tried everything you suggested.  Nothing works.  Sorry but that is the way it is.  Have your tier 2 folks build a system similar and they will see no matter what the ATA drive tries to boot first.
