Diversified Technology CAT904 80286 single board PC

[Tom Uban]

I have a Diversified Technology CAT904 80286 single board PC in a system with a 5.25" floppy drive
running DOS.
I would like to switch the system to use a 3.5" drive and am wondering if anyone has a manual for
the dip switch settings for this board or if I can simply add a 3.5" drive as a 2nd device on the
floppy cable (guessing not without switch changes)?
