You forgot! you forgot the floppy being set as first in the order. It's always something simple.
I think everyone has seen that once or twice while the smart thing was not getting ripped off at some store! If you forget a disk left in a floppy drive and boot... "what? I forgot to take the floppy out...:"
and quickly press the reset button while popping the disk out.
Would you believe I still have a floppy drive installed here? Not that I will see much use out of it I threw it in just in case I needed to rawrite or some other Linux or dos tool. The floppy search is kept disabled.
