This is a Bios problem. Restart computer, immediately keep tapping the F2 and the Bios screen will appear. You can only use ARROW keys to navigate. Read instructions at bottom of screen (different Bios have different ways to navigate and change settings) check each tab for reference to your 32 bit drive and change accordingly. "Save and Exit" it will then restart itself with your new Bios settings. A word of caution... write down all changes from and to so if things go wrong you can re-set the Bios by rebooting and pressing F2. Let me know it that works.
