Tim - Unless your system has a pretty fancy interrupt handler, it seems
unlikely that typeahead will work while ANY program is being loaded from
a floppy, as interrupts from the keyboard would interfere with the operation
of the disk controller (if it uses interrupts) or of the disk-reading software
(if the disk controller doesn't use interrupts).  A fancy interrupt handler
could determine the source of an interrupt (given proper hardware support),
but really rapid typing would still screw things up occasionally unless you
have a really fast processor.  I don't see how a particular program could have
a unique effect on this situation while it is being loaded (that is, before
it even starts to execute).  Are you sure you have the story straight?
