I've tried all the following codes, and none have worked. when I click on Catalyst Control Center to open, it gives me a small black rectangle box to type the passwords in. I type the passwords, but never see any letters, or the white curser move. After a short time, the white curser jumps to the line below the word "Password" and the log in rectangle dissapears. I do have a smal box in the lower right corner of the screen which states "AMD Unsupported Hardware", so all though AMD says it's supported, in reality it isnt, and AMD has made a mistake.
