        Yes, I read that in the instructions before making the change
        but I thought perhaps it was due to a limitation of the original
        Windows XP provided with it which is long gone.

        The other computer now F-14 32 bit, shows cp0/cp1 as 64 bit
        under lshw
        but the basic computer as 32 bit. Is that because it's running
        32 or is that a limitation?

        I know, I should try it, but someone more knowledgeable may know
        the answer?

        Maybe I know the answer already, this Dell shows the same 32 bit
        width and I know I had 64 bit Linux installed on it. Perhaps
        that has some other meaning and my ignorance is showing!
