Basically, I have a M5A97 LE R2.0 and a Seagate 500gb 7200.10 that I ordered off of ebay (dont ask, I won't be using ebay for anything but GPU's from now on) The HDD was a working pull, however from a storebuilt Mac. I don't even know if the guy cleared the drive or not. But what does matter is that when I start up BIOS, I get the message "The current BIOS setting do not fully support the boot device. Click OK to enter the BIOS setup" I've been fooling around in BIOS, especially the CSM parameters which the same message "said" was the problem. Any ideas?
