  In a REAL IBM PC? You bet! The original IBM PC Floppy drive controller
had a 37 pin connector on the back panel. You could connect two drives to
the internal connector and two to the external connector. Many of the thrid
party FD controller cards also had the external drive port. Yes DOS will
recognize the 3rd and 4th drives as C: and D: if no hard drive is
installed. I don't remember what drive letters it assigns if a HD is
present but I THINK they will still be C: and D:.


 If so, how? If I stick
