  According to DOS ver 3.00 Tech reference, Function 0E , Int 21 claims that
 the minimum number of drives (for ver 3.00 and later) is five.  This is consistant with the "lastdrive"=E by default.  This function will return total drives, that is fixed disk and floppy, or 5, whichever is greater.

   A way to determine actual number of floppy's is to use BIOS int11.
   Look in BIOS listing for output (stored in AX register after function call).
