There were two "standard" versions of the
720K 3.5 format, differing in the
cluster and FAT size. One was the definition put out by IBM sometime
around MS-DOS 2.1 and the other, by Microsoft in MS-DOS 4.00 (which was an
abomination).
First official support for 3.5" in PC-DOS was V3.20.
First official support for 3.5" in MS-DOS (OEM'd) was V2.11.
A few machines added support for 3.5" on their own (HP, Gavilan, etc.)
Several versions of Windoze FORMAT (COMMAND LINE!) support /T:80/N:8
which gives a 640K format!
/F:x support seems to have been dropped completely.
