 I don't believe so--Dell sells the Optiplex floppy with a formed cable
 as a single unit.  Here's a photo:

 While the second floppy select probably exists on some pin in the
 support chipset, I don't think that Dell ever intended that more than
 one floppy would be used and so probably never wired the header for
 it.
  
I can say semi-definitively that something serious is missing in the
logic.  I haven't probed into the signals, but a second drive installed
on a connector crimped on before the twist at the end is found by the
BIOS and appears as a device in 'Windows Explorer' but does NOT work.
