Yes, a KFQSA controller creates up to three MSCP controllers;
one for each device connected (in my VAX 4705A, which only HAS
three drives.. it may support the full 7 drives..)
So, if you have a KDA50 as well, that could create up to 4
of em. Make sure the one you want to *boot* from is the one
at the MSCP default (17772150 comes to mind?) address.

The KDA probably sits at the default address, with the KFQSA
also using that address, indeed. Most KFQSA's are configured
to allocate as many controllers as needed, with the first one
sitting at the MSCP-default address, soo..
