Thanks Bill. My original question today was "how do you move F7 from
this IDE to a SATA hard drive?
I have got tiny tid bits of information. Now I have no where near the
total answer I was looking for, and now expect it will not be
forthcoming :-)
And so many times in my life I will just figure it out myself. Takes a
lot longer but at 72 years old I know some of the world likes to see you
unhappy.
