This message is handled by the RAM resident part of the disk driver
(alias "RAM BIOS" or "IBMBIO.COM" on your system disk).  On a single
floppy system, it pretends that there are actually two floppy drives,
keeps track of which logical "floppy drive" was accessed last, and
then instructs the user to insert the other floppy if necessary.

This was a kludge to allow poorly written software (i.e. software that
"required" two floppy drives) to run on the single floppy PC's.

Hope this helps.
