Thankyou for posting the documentation. I appreciate you taking the time to help.
Please don't assume that I don't search and read before I post, because I generally do.
I was going from memory, but it's not quite what it used to be.
I have seen this info before, but could not find it again when needed. The mb and raid manual are 2 separate documents, and I guess I had tunnel vision on the mb manual.
I did not mean to change the topic from the original post, it just seemed that the question had been answered and kind of flowed along my way.
The function of my raid controller can be set to RAID or ATA in cmos set up, so I am not convinced that "For HDDs only" is written in stone.
When set to ATA, UMDA 6 appears next to the drive during boot up, so when time allows, I will experiment with it and post back.
Thanks Tim, and sorry for any problems I may have caused for you, in your quest to help me.
I think you had my question nailed in post #6.
