Only the very tail end of the Pentium 4 processors have the 64 bit extensions More about : run bit bit system grandta13 September 4, 2012 8:37:24 PM I have several hard drives I'm testing, many of which are running Windows 7 (I believe that they are all 64-bit Professional), and I only have 32-bit boards. When I try to boot the OS, I see the boot screen for about 2 seconds, then the system restarts, and Windows trys to perform some System Restore functions. The processor is a Pentium 4 and the hard drives use SATA connections. I have looked elswhere on the Internet and have found nothing pertaining to using an existing 64-bit OS on a 32-bit board. Any help on this subject will be appreciated. ahnilated a b $ Windows 7 September 4, 2012 8:41:22 PM " I have looked elswhere on the Internet and have found nothing pertaining to using an existing 64-bit OS on a 32-bit board.
