I found a youtube video showing how to do this and followed it. But then I got the message "The size of the system memory has changed" and a suggestion to reallocate memory, which I did several times and always got the same message. there at least 10 minutes max. You will eventually see a dialog box that says "Press F1 to continue or F2 to enter setup". I let the "reinstall memory" message stay on the screen for a few minutes (maybe 3.4) and like magic the computer took care of the problem. It prompted me to press F1, which I did and everything was fine. The computer now runs much faster as expected and I am very happy with it. Good price, fast delivery, thank you.
