Replying to a message from Brian McCloud to Jon Gentil,
About What's wrong with this???, On Wed, Jul 16, 1997
JG>Ok, I'm writing a small bootstrap loader which loads whatever is on Sector

No, there's nothing loaded at all..  like I said, I load it from a 1.44 
floppy, which I BOOT from to load the program.  Nothing is loaded at all.
