Kind of figured that. Where I missed the beat was at the bootloader 
install. I was NOT paying attention.....

And I am off to Europe with no helpdesk contact info. And I only get to 
my office (I am in Detroit, my office outside of Harrisburg PA) once a 
quarter. So I am trying to contact a colleague in the local office to 
get me the tech support guy. He straighted out the boot loader on this 
box once when the auto encypt install failed....

Thanks anyway gang.
