I re-read what he wrote and that is not clear to me. All he said was he
wanted a CD or a diskette that will boot all machines. That can be read as
"I want to make 10 copies of that CD and put it in all 10 machines" or "just
one disk and I can put it in any of 10 machines".

I can't imagine why anyone would need a 'boot server' but if so, he's waaay
out of my ballpark.
