 I tried typing in DB, and the others that it said were "Present", but
 just got a Syntax Error. 
It will want the unit number as well (most of those controlers will
handle 2 or 4 disks), so it wants you to type "DB0" or possibly
"DB0:".

    DB should be
the main disk.  What does DB stand for? Is it the type of controller, a

D is for disk, B is the disk (or sometimes, controller) type.  176700
is the address for an RP04 controller.
