Because of that the boot loader can load anything you specify at the
prompt, it would probably be rather easy to write a small stand-alone
diag program that could check whatever is interesting. The boot loader
cannot have a size bigger than 48K, so it's best to have only the 
needed things in it. It has already grown a little bit too big.
