I sure appreciate your help.  Unfortunately, that was one of the first
things I did.  Joe Eubank is helping me on this project, and he just
sent me a note that he was able to get Centos to boot from a usb stick
so we may be able to bypass our problem.  I'll keep everyone informed so
others can benefit from our trial and error.
