I was thinking of support WITHOUT an additional device driver.

I still have the OEM customization guides for MS-DOS
1.25 and 2.00. The
preface to 2.00 states that eventually it would support the entire set of
Xenix functions. Uh-huh.
any hope of a copy?
One could in PC-DOS 3.?0 use DRIVPARM in CONFIG.SYS
but you had to suffix
the DRIVPARM with a string of control-A's.
3.20
I think MS would love to kill off floppy support
