hello and thanks for your report!
we have added your board already some time ago, but i just noticed that there exist two versions:
http://www.msi.com/product/mb/K9A2-Platinum.html http://www.msi.com/product/mb/K9A2-Platinum-V2.html
they can be easily distinguished by the additional sata controller (promise t3) which also provides two esata ports on the atx back panel. V2 does not have those. can you tell us which version you have please?
