Later in 1986, PC-DOS 3.30 supported 1.4M.
The 720K 3.5" drive was introduced by IBM in 1986 as an option for the
standard PC-PC/AT product line. What I recall about the PS/2 was the
support for DSHD and DSED 3.5 diskettes. In fact, drivers had been
available earlier than PC-DOS 3.2 from third parties for 720K 3.5" drives.
