THAT would be version 3.20 of bothe MS-DOS and

They also had DRIVPARM as a CONFIG.SYS "command", that would reconfigure
without adding another drive nor driver in [precious] RAM. But, that was
not documented in the PC-DOS manuals, and for reasons as yet unexplained,
would not work with the real IBM BIOS ROMs, although it did work [with
either PC-DOS OR MS-DOS] with Award, Phoenix, and several generic BIOS
ROMs.
At least one of the PC-DOS versions (3.3?) supported DRIVPARM, but "hid"
it requiring that the "DRIVPARM=" be followed by (IIRC) 3 hex 01
characters. Bizarre. DRIVER.SYS worked okay, though.
