This is one of the messages I was referring to (#289 in this thread).
What makes me wonder about this is that my controller has a RAID option (the default, to which it is currently set) and an option to use RAID if the HDDs are assigned to a RAID and AHCI if they are not. If WindowsStar is correct, there would seem to be no difference between these two options. If my current drives were configured as a RAID right now, the default setting on my controller would manage the RAID. According to WindowsStar, since my drives are NOT configured as a RAID, they should be running in AHCI. This is exactly how the controller option that I am NOT using is supposed to work. So, how are these option different, given what WindowsStar has said?
Also, when I look at the Registry option that needs to be changed to enable AHCI, it is currently zero. Does that have to be 3 in order for AHCI to operate, or does changing it just allow you to change the BIOS options?
I want to be sure that I have the benefits of AHCI for my SSD, but if I don't need to change the registry and BIOS, I would rather not.
FWIW, there is no IDE controller on this machine. Only a RAID controller.
EDIT:
OK. I see that I had the registry values reversed. If the msahci value is 0, then it is set for AHCI. So, apparently AHCI is activated without my having to do anything. However, I am still confused by the apparently redundant controller option in my BIOS, but I can live with being confused.
Thanks again.
