     Well. Can I guess?

______________O\_/_________________________________\_/O______________
/I
    Specifies an electronically compatible 3.5-inch floppy disk drive.
    (Electronically compatible drives are installed on your computer and use
    your existing floppy-disk-drive controller.) Use the /I switch if your
    computer's ROM BIOS does not support 3.5-inch floppy disk drives.

              O/~\                                 /~\O

     If I right understand, this forces MS-DOS to load BIOS extension, which
replaces or expands outdated BIOS (XT?) interrupt handler, which not support
corresponding floppy devices.

P.S. I think, regardless of correctness of my speculations, /I switch are
long time ago outdated.
