I'd give you a hug if I could for rambling.  You stated that perfectly.  
I only sent you the email off list because I am unsure when my content 
is what is wanted.  In any event, I have not yet connected the PATA 
drive.  It sounds like our motherboards have an identical HDD setup.

My computer is running so great right now, I don't want to take a chance 
on screwing it up.  Things are moving so fast that applications are 
opening just slightly before I click on them, Hah!  I think I will 
reinstall the PATA back in the old box just for formatting.  Then it 
can't screw things up.  Not that much extra work anyway.  You guys are 
so great.  Thanks again.
