!O...  I only *learned* about XT setup in my Computer Electronic Tech course
I took in 1995, but never put that part into practice...  I have forgotten 
much.  Thanks for the refresher!

But I do remember using SETUP from a floppy.  But I always thought what a 
*bad* idea it was to setup your computer with a disk.  Unless that disk was 
nailed to the computer, the next time you wanted to change something you 
would have to spend have the day looking for the floppy to do a change that 
would only take five minutes.
