The reason is that if the Hard disk goes bad in any way, you can get controll
through the floppy.  A bootable floppy can be inserted any time there is
a real problem.

The ALT key handles most logical errors (like bad .prg in /auto and bad .acc 
programs) but not all hardware errors.  Such as if the Hard disk sector 0
reads into the wrong area, or forgets to stop reading.

Anyway, It is always best to give the user a choice, and boot floppy first
is the way to do that.
